Xcode 11 Swift Packages incompatible with "flutter build" #44811
Description
We are trying to use a Swift package using the newly integrated Swift Package Manager in Xcode 11 in our iOS specific platform code. While it works as long as we build the app via Xcode, we cannot build or run the app using the flutter tool.
Steps to Reproduce
- Create a new Flutter app
- Open the Xcode project
- Select "File" -> "Swift Packages" -> "Add Package Dependency"
- Add any package, e.g. "https://github.com/doneservices/ApsEnvironment"
- Try and build the app: "flutter build ios"
- Observe below documented error
Target Platform: iOS
Target OS version/browser: iOS 13
Devices: iPhone 8, iPhone 11 Pro
command
flutter build ios
exception
ProcessException: ProcessException: Process "/usr/bin/xcodebuild" exited abnormally:
xcodebuild: error: Could not resolve package dependencies:
Packages are not supported when using legacy build locations, but the current project has them enabled.
Command: /usr/bin/xcodebuild -list
