Swift Package license generation

[fgeistert]

Currently, we use LicensePlist to automatically generate licenses. However, we only consider dependencies inside the Xcode project and dependencies from each Swift Package are ignored. This is a problem, especially with the the SPM-based modularization of the project.

To fix this, the following snippet can be used:

export PATH="$PATH:/opt/homebrew/bin"

if which /usr/libexec/PlistBuddy >/dev/null; then
 version="$MARKETING_VERSION"
 build="$CURRENT_PROJECT_VERSION"
 /usr/libexec/PlistBuddy "$SRCROOT/$PRODUCT_NAME/SupportingFiles/Settings.bundle/Root.plist" -c "set PreferenceSpecifiers:2:DefaultValue $version ($build)"
else
echo "warning: PlistBuddy not found"
fi

if which license-plist >/dev/null; then
 base_command="license-plist --output-path $PRODUCT_NAME/SupportingFiles/Settings.bundle --config-path $PRODUCT_NAME/SupportingFiles/license_plist.yml --package-path $PROJECT_FILE_PATH/project.xcworkspace/xcshareddata/swiftpm/Package.swift --suppress-opening-directory --package-paths"

 # Find all Package.swift files in Modules/ directory and append them to the command
 for package in $PROJECT_DIR/Modules/*/Package.swift; do
   base_command+=" $package"
 done

 eval $base_command
 
else
 echo "warning: license-plist not installed, download from https://github.com/mono0926/LicensePlist"
fi

Note: only the execution of the license-plist was changed, the top part stays the same.
