Command line utility to profile compilation time of Swift project.
This tool is developed in working time for Cookpad.
gem install xcprofiler
-
Add
-Xfrontend -debug-time-function-bodiesbuild flags inOther Swift Flagssection on your Xcode project.
-
Build your project
-
Execute
xcprofiler
$ xcprofiler [PRODUCT_NAME or ACTIVITY_LOG_PATH] [options]
xcprofiler searches the latest build log on your DerivedData directory.
You can also specify the .xcactivitylog.
$ xcprofiler MyApp
$ xcprofiler ~/Library/Developer/Xcode/DerivedData/MyApp-xxxxxxxxxxx/Logs/Build/0761C73D-3B6C-449A-BE89-6D11DAB748FE.xcactivitylog

You can use reporters to output tracking logs.
require 'xcprofiler'
profiler = Xcprofiler::Profiler.by_product_name('MyApp')
profiler.reporters = [
Xcprofiler::StandardOutputReporter.new(limit: 20, order: :time),
Xcprofiler::JSONReporter.new(output_path: 'result.json'),
Xcprofiler::BlockReporter.new do |executions|
do_something(executions)
end,
]
profiler.report!You can also implement your own reporters.
See implementation of built-in reporters for detail.
You can integrate xcprofiler to danger.
