pod init does not work on Xcode projects created using Xcode 16 beta #153402
Description
Problem
CocoaPods's pod init command is broken on projects created using Xcode 16 beta: CocoaPods/CocoaPods#12456
Work
- If Xcode 16 ships before CocoaPods fixes this issue, add known workarounds to our add-to-add project setup instructions (ex: create your iOS project using Xcode 15)
-
pod installdoes not work after adding a new test/watch/extension/other target with Xcode 16 #156733 - When CocoaPods fixes this issue, update the minimum required CocoaPods version in
flutter doctorand docs. Tracked by Update minimum recommended CocoaPods version to support Xcode 16 synchronized groups #157737
Steps to reproduce
- Create a new SwiftUI project using Xcode 16 beta 5
- Run
pod initin the created directory
You'll get the following error:
Error output...
$ pod init
