SwiftGen CHANGELOG

6.1.0

Changes in core dependencies of SwiftGen

New Features

Bug Fixes

  • Colors: Fix an issue where the public access modifier was not being added correctly in the literals-swift3 and literals-swift4 templates when the publicAccess parameter was specified. Also remove some uneccessary public access modifiers from the swift3 and swift4 templates.
    Isaac Halvorson #549

Internal Changes

  • Resolve path if the binary is a symbolic link in order to find bundled templates.
    Liquidsoul #559
  • Update to SwiftLint 0.30.1 and enable some extra SwiftLint rules.
    David Jennes #574 #583

6.0.2

Changes in core dependencies of SwiftGen

Bug Fixes

  • Strings: rolled back the changes in #503, to ensure %% is correctly unescaped.
    David Jennes #542
  • Strings: generate the correct types for %c and %p.
    David Jennes #543
  • SPM/Mint: SwiftGen now provides correct version information, instead of "0.0".
    David Jennes #544

6.0.1

Changes in core dependencies of SwiftGen

Bug Fixes

Internal Changes

6.0.0

⚠️ This major version is a big milestone in which a lot of refactoring and cleaning has been done. Many features added over previous releases have been reworked and unified, while also preparing SwiftGen for future additions. This means that you'll need to adapt your configuration files (or command line invocations) and custom templates to work with this new major version.

Read the SwiftGen 6.0 Migration Guide for a list of changes you'll need to apply.

Changes in core dependencies of SwiftGen

Breaking Changes

  • Don't normalize string keys while parsing, let all transformation be done on template side. This makes the developer responsible to keep the language file organized, duplications won't be removed.
    Diego Chohfi #257
  • Remove Swift 2 support.
    David Jennes #420
  • Renamed the storyboards command to ib, to better reflect it's purpose. An alias for storyboards still exists, but it will be removed at some point.
    David Jennes #423
  • XCAssets: the generated templates won't namespace groups by default anymore, use the forceProvidesNamespaces flag to enable this behaviour again.
    jechris #453
  • XCAssets: the templates won't generate any all-values accessors anymore by default. Use the allValues flag to enable this behaviour again. Note: this replaces the old noAllValues flag (with an inverse behaviour).
    David Jennes #480
  • XCAssets: Dropped the deprecated allValues constant, use the type specific constants such as allColors, allDataItems and allImages. The default value of imageAlias has also been changed from Image to AssetImageTypeAlias, to be consistent with the other types.
    David Jennes #482
  • Interface Builder: split up the storyboards template into 2 parts, one for scenes and one for segues.
    David Jennes #419

New Features

  • Add ability to list all custom fonts and register them using FontFamily.registerAllCustomFonts.
    Olivier Halligon #394
  • Add support for Swift Package Manager and Mint.
    Yonas Kolb #411
  • The swiftgen.yml config file now accepts multiple outputs for each command, allowing you to generate multiple outputs from the same files and content. This also means that the output parameter is now deprecated, in favour of the outputs parameter, and it may be removed in a future version of SwiftGen. Similarly, the paths parameter has been renamed to inputs for consistency. You can always use swiftgen config lint to validate your configuration file.
    David Jennes #424 #510
  • Use swiftlint:disable all in generated files to avoid interference with SwiftLint rules custom to the host project.
    Frederick Pietschmann David Jennes #409 #506
  • XCAssets: Added support for NSDataAssets.
    Oliver Jones #444
  • Organised the generated code in sections for better readability, with all generated constants at the top of the file.
    David Jennes Olivier Halligon #456 #481
  • Added support for JSON, Plist and YAML files using the swiftgen json, swiftgen plist and swiftgen yaml commands. The parsed contexts and the generated files for each command have been kept quite similar, for easier switching between file formats.
    John T McIntosh Toshihiro Suzuki Peter Livesey David Jennes #379 #359 #288 #188 #493 #504
  • Updated the playgrounds with the new json, plist and yaml commands, and updated the other pages to reflect the template changes.
    David Jennes #495
  • We're deprecating the old --template CLI option in favor of --templateName, to better match the naming of the other options and the configuration file. The old --template option will remain until the next major version.
    David Jennes #509

Bug Fixes

  • Fix memory leak in generated code for Fonts.
    Olivier Halligon #394
  • Interface Builder: ensure the templates handle GLKViewController, AVPlayerViewController and NSPageController correctly.
    David Jennes #404 #414
  • Interface Builder: ensure the parser can handle files with and without "trait variations".
    David Jennes #367 #429
  • Restrict SceneType and InitialSceneType to UIViewController when not targeting AppKit. When targeting AppKit, remove superfluous Any.
    Darron Schall #463 #464
  • Fonts: disable a warning in generated font files for projects with conditional_returns_on_newlines SwiftLint rule enabled.
    Ryan Davies #436 #465
  • Interface Builder: the parser and templates now handle the "Inherit module from target" setting.
    David Jennes #435 #485
  • Strings: the parser now correctly handles formats such as % d and %#x.
    David Jennes #502
  • Strings: ensure strings without arguments are not processed using String(format:).
    David Jennes #503

New Features

  • Added Swift 4 templates. Use -t swift4 or whatever variant you want to use (see swiftgen templates list for the available names).
    David Jennes SwiftGen/templates/#67
  • XCAssets: Added support for named colors. When using swiftgen xcassets the bundled templates will now also include colors found in the Asset Catalog in addition to the images.
    David Jennes SwiftGen/templates/#68
  • Fonts: the path to fonts will now default to just the font filename, but you can disable this behaviour by enabling the preservePath parameter.
    David Jennes SwiftGen/templates/#71
  • Colors: new template that uses #colorLiterals.
    Use swiftgen colors -t literals-swift3 / swiftgen colors -t literals-swift4 to use them.
    David Jennes SwiftGen/templates/#72

Breaking Changes

  • Removed deprecated CLI options. Please consult the migration guide should you still use them.
    David Jennes #301
  • Disable default value for named template option and ensure that there is a template option.
    Liquidsoul #283
  • Templates are now grouped by subcommand on the filesystem. This is only important if you had custom templates in the Application Support directory. To migrate your templates, place them in a subfolder with the name of the subcommand, and remove the prefix of the template filename.
    David Jennes #304
  • The images command has been renamed to xcassets to better reflect its functionality.
    Olivier Halligon #317

Notable internal changes from other SwiftGen repositories

  • Switch back from actool to an internal parser to fix numerous issues with the former. This fixes issues a few people encountered when using asset catalogs that contained some of the less common set types.
    David Jennes #228 SwiftGen/SwiftGenKit#43

4.2.1

Changes in core dependencies of SwiftGen

Bug Fixes

  • Fix a bug in which the version of SwiftGen was reported as v0.0 by swiftgen --version.
    Olivier Halligon

Internal Changes

4.2.0

Changes in core dependencies of SwiftGen

New Features

  • You can now pass custom parameters to your templates using the --param X=Y syntax.
    @djbe #265
    • This command-line option can be repeated at will and used to pass structured custom parameters (e.g. --param tabs=2 --param foo.bar=1 --param foo.baz=2).
    • You can then use them in your templates using e.g. {{param.tabs}}, {{param.foo.bar}} & {{param.foo.baz}}.
  • Templates can now access environment variables via the env key of the Stencil context (e.g. {{env.USER}}, {{env.LANG}}).
    @djbe #265
    • This is especially useful when integrating SwiftGen as a Script Build Phase in your Xcode project as you can then access Xcode Build Settings exposed as environment variables by Xcode, e.g. {{env.PRODUCT_MODULE_NAME}}.

Notable new features from other SwiftGen repositories

Deprecations

In preparation for an upcoming cleanup of SwiftGen to remove some legacy code as well as Stencil old variables, tags and filters, and change the default templates to Swift 3, some things are being deprecated and will be removed in the next major version 5.0.

As a result, if you wrote custom templates, you should already prepare for the upcoming 5.0 by migrating your templates to use the new variables (already avaiable in SwiftGen 4.2 / SwiftGenKit 1.0).

See #244 and the Migration Guide for a list of deprecations and their replacements.

Bug Fixes

Notable bug fixes from other SwiftGen repositories

Internal changes

  • SwiftGen has migrated to its own GitHub organization 🎉.
  • SwiftGen has been split in multiple repositories and separate modules.
    @AliSoftware @djbe #240 #265
    • The present SwiftGen is the CLI parsing. It is in charge of calling the frameworks, feeding them appropriate parameters according to the command line arguments.
    • SwiftGenKit is the framework responsible for parsing your assets/resources and turning them into a structured representation compatible with Stencil templates.
    • StencilSwiftKit is a framework adding some extensions to the template engine Stencil used by SwiftGen. It adds some tags and filters as well as convenience methods shared both by SwiftGen itself and by Sourcery.
    • The SwiftGen templates has been moved into a dedicated templates repo so they can evolve and be unit-tested separately of SwiftGen.

Note: The next minor version will focus on bringing more documentation for all this new structure and improve ease of future contributions.

4.1.0

New Features

  • Added a script reference to simplify and automate localization of existing non localized project.
    HuguesBR
  • Added a storyboards-osx-swift3 template.
    Felix Lisczyk #225
  • Added a strings-no-comments-swift3 template that does not include the default translation of each key.
    Loïs Di Qual #222
  • Images: new dot-syntax template, use dot-syntax-swift3 or dot-syntax (for Swift 2.3).
    David Jennes #206
  • Reworked the "dot-syntax" and "structured" templates to use the new macro and call tags, which greatly simplifies the templates, and also removes the limitation of 5-level deep structures.
    David Jennes #237
  • Storyboards: automatically detect the correct modules that need to be imported. The --import option has therefore been deprecated, as well as the extraImports template variable. Instead use the the new modules variable, which offers the same functionality.
    David Jennes #243
  • Support multiple input paths for some commands.
    David Jennes #213
    • fonts accepts multiple input directories, all found fonts will be added to the families template variable.
    • images now supports multiple asset catalogs as input. Templates can now use the catalogs variable to access each individual catalog.
    • storyboards accepts multiple paths (to folders or storyboard files). All found storyboards will be available in the storyboards template variable.

Bug Fixes

  • Strings: fix issue with dot-syntax-swift3 where function definitions were not Swift 3 guidelines compliant.
    David Jennes #241 #247
  • Snake cased keys with uppercase letters are correctly camel cased again.
    Cihat Gündüz #226 #233

    AndrewSB #190
  • The swiftgen images command now uses the actool utility to parse asset catalogs, ensuring that the parser correctly handles namespaced folders.
     ⚠️ Note that you now have to specify the exact path to your .xcassets assets catalogs  when using swiftgen images (and not just a directory to parse).
    David Jennes #199

New Features

  • Add support for multiline strings in *.strings file.
    Jeong Yonguk #192
  • Add option to add import statements at the top of the generated swift file (for storyboards) using the import flag.

    Afonso #198

3.0.1

3.0.0

  • Add template that calls NSLocalizedString() separately for each string, which is useful when trying to extract strings in the app to a .strings file.
    Ahmet Karalar
  • Add some file_length and similar SwiftLint exceptions in bundled templates, as files generated by SwiftGen might contain lots of constants and can be long by design.
    Olivier Halligon
  • Error messages ("template not found", etc) are now printed on stderr.
    Olivier Halligon
  • Add more swiftgen templates subcommands.
    Olivier Halligon
    • swiftgen templates list lists all the available templates
    • swiftgen templates which <name> prints the path to the template named <name>
    • swiftgen templates cat <name> prints the content to the template named <name>
    • <name> here can be either a subcommand name like colors or a composed name colors-rawValue for a specific template.
  • Fix swift 3 renaming change in strings-swift3.stencil.
    Kilian Koeltzsch #150
  • Fix non-custom class, non-base view controller handling in storyboards-swift3.stencil.
    Syo Ikeda #152
  • Add strongly typed initialViewController() overrides for storyboard templates if available.
    Syo Ikeda #153 #163
  • Add support for font files containing multiple descriptors.
    Chris Ellsworth #156
  • Update deprecated usage of generics for Swift 3 / Xcode 8 beta 6.
    Chris Ellsworth #158
  • Fix case when missing positional parameters, which leads to parameters in the enum with unspecified type (undeterminable from the Localizable.strings format analysis) where reported as Any — which is not a CVarArgType. Now using UnsafePointer<()> arguments instead for such odd edge-cases that should never happen anyway.
    Olivier Halligon
  • Now reports an error when it failed to parse a color in a color input file.
    Olivier Halligon #162
  • New Strings template (available via -t dot-syntax), allowing string keys containing dots (like foo.bar.baz) to be organized as a hierarchy and accessible via dot syntax.
    Cihat Gündüz #159
  • Update Swift 3 templates to use lowercase enums.
    Olivier Halligon #166
  • New Strings template (available via -t dot-syntax-swift3), allowing keys with dots in Swift 3 (see above).
    Cihat Gündüz #168

💡 You can now create your custom templates more easier than ever, by cloning an existing template!

e.g. to clone the default strings-default.stencil template:

  • use swiftgen templates cat strings --output strings-custom.stencil
  • modify the cloned strings-custom.stencil template to your liking
  • use it with swiftgen strings … --templatePath strings-custom.stencil … in your projects!

Important Notes

  • Some keys for various templates have changed to provide more flexibility and enable some new features in the templates. As a result, if you created your own custom templates, they might not all be totally compatible with SwiftGen 3.0.0 (hence the new major version). Please read the Custom Templates documentation to find out the new Stencil context keys and update your custom templates accordingly.

If you're using one of the bundled templates, all of them have been updated appropriately.

  • Also if you use Swift 3, and thus use the -t swift3 flag to use the Swift 3 templates, be advised those has been modified to take the latest Swift 3 modifications into account (including naming convensions) so your code might need to be updated according to match the latest Swift 3 recommendations.

2.0.0

Note: The Stencil context keys (the name of the variables used in templates) for storyboard has changed a bit. Especially, class has been renamed into customClass (see #131) to better describe the intent (as this isn't defined if there is no custom class set in the Storyboard), and new keys isBaseViewController and baseType has been added.

This means that if you did implement your own custom templates for storyboards (instead of using the bundled ones), you'll have to remplace {{class}} by {{customClass}} in those storyboard templates, otherwise they'll probably stop working as expected. That's the main reason why the version has been bumped to a major version 2.0.0.

1.1.2

  • Fix issue introduced by 1.1.1 in storyboard templates not returning.
    Ben Chatelain #138

    Ilya Puchka #81

0.7.4

Enhancements

0.7.3

Fixes

  • Restructured storyboard templates to work around an LLVM issue with nested types.
    Ryan Booker #57

  • Add a performSegue(_:sender:) extension on UIViewController to accept a StoryboardSegue as parameter.
    You can now for example call vc.performSegue(UIStoryboard.Segue.Wizard.ShowPassword).
    #37

SwiftGen now comes bundled with some alternate templates, especially colors-rawValue, images-allvalues and storyboards-lowercase, in addition to the default templates.

Fixes

  • Now swiftgen storyboards doesn't generate duplicate enum cases for identical segues (those having equal identifiers and shared custom class).
    @filwag #43
  • Fix compilation issue for storyboards without any scene.
    Viacheslav Karamov #47
  • Propose an alternate template using lowercase names, especially for when storyboard identifiers match view controller class names.
    Viacheslav Karamov #48
  • Introduced an image-allvalues template that exposes the list of all images in a static let allValues array.
    Ahmed Mseddi & Guillaume Lagorce #44
  • Fix issue with Storyboards without any StoryboardID (all scenes being anonymous) not extending StoryboardScene.
    #36

0.6.0

New Features: Templates

  • SwiftGen now uses Stencil template engine to produce the generated code.
  • This means that the generate code will be easier to improve.
  • This also means that you can use your own templates to generate code that better suits your needs and preferences, using swiftgen … --template FILE ….

Fixes

    @Igor-Palaguta #34

0.5.1

Fixes

  • Installing via rake install or brew install will now copy the Swift dylibs too, so that swiftgen installation won't depend on the location of your Xcode.app (so it'll work on every machine even if you rename your Xcode).
  • Fixed links in Playground and Licence headers in source code.

0.5.0

New Features

  • Migrating to Commander to parse the CLI arguments.
    23 #30
  • swiftgen is now a single binary, and the subcommand names have changed to be more consistent.
    #30
  • New --output option.
    #30

You must now use the subcommands swiftgen images, swiftgen strings, swiftgen storyboards and swiftgen colors. See swiftgen --help for more usage info.

Fixes

0.4.4

  • Updated Unit tests for latest Swift 2.0 & tested against Xcode 7.1
  • Fix small typos in code
  • Guard against empty enums

0.4.3

0.4.2

  • Added import Foundation on top of swiftgen-l10n generated code.
    @Nick11 #12

0.4.1

  • Updated for Xcode 7 Beta 5
  • swiftgen-storyboard now allows to take a path to a .storyboard file as argument (as an alternative to give a path to a whole directory)
  • The -v and --version flags are now recognized and print the executable version.

0.4.0

  • Reorganized files into an Xcode project with one target per executable.
    #2
  • Added Unit Tests (one per executable + one for common code).
    #2
  • Improved SwiftGen-L10n parsing of format strings and placeholders.
    #4 #5 #6
  • Updated Rakefile so that it now invokes xcodebuild install. You can now easily build & install all swiftgen-xxx executables in /usr/local/bin or anywhere else.
  • Added a version string (date + sha1) to the built executables (displayed when invoked with no argument)

0.3.0

  • Reducted the default code generated by SwiftGenColorEnumBuilder to avoid clobbering the UIColor namespace
  • Changed the "namespacing enum" in UIStoryboard to a struct to avoid confusion with the inner enums
  • The UIStoryboard.Scene enums now use static func instead of static var for the dedicated ViewController constructors ^(†)

^(†) because it feels more explicit that calling a function like UIStoryboard.Scene.Wizard.validatePasswordViewController() will actually instantiate a new ViewController, rather than returning an existing one.

0.2.0

  • Added Segues enums to UIStoryboard to be able to access their identifiers easily.
    @esttorhe #8
  • Added this very CHANGELOG.md

0.1.0

Considered to be the first cleaned-up version, far from finished but really usable with clean code.
