Pointers for migration between major versions.
- In the Build Phase, some changes are needed, see an example screenshot:
- Uncheck "Based on dependency analysis" so that R.swift is run on each build
- Remove
$TEMP_DIR/rswift-lastrun
from the "Input Files" of the Build Phase - Keep
$SRCROOT/[YOUR_PATH]/R.generated.swift
in the "Output Files" of the Build Phase unchanged
- Make sure you use Xcode 10 since we've adjusted to the SDK changes
- At the moment we are compatible with both Swift 4 and 4.2, this is more an accident then a feature, beware that we might drop Swift 4 support anytime.
If you are using the "New Build System":
- In the Build Phase you must perform some changes:
- Change the script to give the explicit output file, for example:
"$PODS_ROOT/R.swift/rswift" generate "$SRCROOT/[YOUR_PATH]/R.generated.swift"
- Add
$TEMP_DIR/rswift-lastrun
to the "Input Files" of the Build Phase - Add
$SRCROOT/[YOUR_PATH]/R.generated.swift
to the "Output Files" of the Build Phase
- Change the script to give the explicit output file, for example:
If you are using the "Legacy Build System":
- Add the flag
--disable-input-output-files-validation
and do not add input/output files to the Build Phase.
- Make sure you use Swift 4 / Xcode 9 since we've adjusted to the syntax and SDK changes.
- Running R.swift now requires the
generate
command, check the error R.swift outputs for upgrade instructions - Capitalization of methods and properties might have changed, in these cases the compiler should generate a fix-it for you.
- Support for CLR-files is deprecated, use the new named Color assets instead where possible.
- CLR based colors are moved from
R.color.*
toR.clr.*
- Support for CLR files will be removed in a later version
- At the moment we are compatible with both Swift 3.2 and Swift 4, this is more an accident then a feature, beware that we might drop Swift 3.2 support anytime.
- If you upgrade from Swift 2 we advise you to first migrate to Swift 3 / R.swift 3.0 and when that is done apply the migration to Swift 4 / R.swift 4.0
- Make sure you use Swift 3 / Xcode 8 since we've adjusted to the syntax changes.
- If you want to use Swift 2.3 / Xcode 8 use the latest R.swift 2 release.
- Some methods are renamed to match the new Swift 3 naming conventions, there are annotations available so the compiler can help you migrate.
- Make sure you use Swift 2.2 / Xcode 7.3 since we've adjusted to the syntax changes.
- iOS 7 support is dropped, use R.swift 0.13 if you still have to support it.
- Generated code now depends on the R.swift.Library, CocoaPods users don't need to do anything. Manual installation users need to include this library themselves, see the readme for instructions.
- In general; properties that created new stuff are now functions to represent better that they actually create a new instance.
R.image.settingsIcon
changed toR.image.settingsIcon()
R.file.someJson
changed toR.file.someJson()
R.storyboard.main.initialViewController
changed toR.storyboard.main.initialViewController()
R.storyboard.main.someViewController
changed toR.storyboard.main.someViewController()
- In general; Where you needed to use
.initialize()
to get the instance, a shorter function is available now:
R.storyboard.main.initialize()
changed toR.storyboard.main()
R.nib.someView.initiate()
changed toR.nib.someView()
- Nib root view loading changed from
R.nib.someView.firstView(nil, options: nil)
toR.nib.someView.firstView(owner: nil)
- Typed segue syntax changed from
segue.typedInfoWithIdentifier(R.segue.someViewController.someSegue)
toR.segue.someViewController.someSegue(segue: segue)
- Runtime validation changed:
R.validate()
now throws errors it encountersR.assertValid()
asserts on errors and only performs action in a debug/non-optimized build- For regular use cases using
R.assertValid()
is recommended
