Question Subject

Setting "Apple Generic Versioning" through Fastlane

Question Description

I am building a Unity Xcode project. The Xcode project is generated from scratch every time Unity runs a build.

In order to use Fastlane's increment_build_number action, the Xcode project must be configured to use "Apple Generic Versioning". Yes, I have read the document how to enable this through Xcode. However, I am building a CI system, so I cannot manually setup the Xcode project everytime.

Is there no way to set Xcode to use "Apple Generic Versioning" through some Fastlane action?

It seems like you have not included the output of fastlane env

To make it easier for us help you resolve this issue, please update the issue to include the output of fastlane env 👍

Right now, my only option is to run sed or perl outside of fastlane. However fastlane already provides actions for things like enabling/disabling automatic signing, so why not this?

p.s. what's the best action to run perl from within a fastlane file?

You can change the build settings using the Xcodeproj module. We do this in our app to manually change the signing settings: https://github.com/iotaledger/trinity-wallet/blob/develop/src/mobile/ios/fastlane/Fastfile#L12. In this case, you could try:

item.build_settings['VERSIONING_SYSTEM'] = "Apple Generic"

To get the name that the Xcodeproj module will use, go to the Build Settings tab and then go to Editor > Show Setting Names. That will change the titles to their actual names, e.g. Versioning System -> VERSIONING_SYSTEM

You can change the build settings using the Xcodeproj module.

That is very helpful!

How can I make sure Xcodeproj module (from what I understand, it's a Ruby library, rather than Fastlane) remains uptodate when Xcode version changes?
