[SwiftPM] FlutterGeneratedPluginSwiftPackage uses Flutter's minimum iOS version, instead of looking at project settings #162072
Description
Steps to reproduce
- Create a new Flutter project with Flutter 3.27 or higher
- Ensure that the project uses SwiftPM
- Add the following dependencies to the project: (see the attached pubspec.lock for exact versions)
firebase_analytics: ^11.4.1
firebase_core: ^3.10.1
firebase_crashlytics: ^4.3.1
firebase_messaging: ^15.2.1
- Specify a higher minimum iOS version, per the Firebase requirement
IPHONEOS_DEPLOYMENT_TARGET = 13.0;inios/Runnerxcodeproj/project.pbxprojMinimumOSVersionto13.0inios/Flutter/AppFrameworkInfo.plistplatform :ios, '13.0'inios/Podfile- override the minimum ios deployment target for pods using the following in the Podfile
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
end
end
end
- Try to build the iOS app in XCode
- The build fails with an error like the following: (see the screenshot)
The package product 'firebase-analytics' requires minimum platform version 13.0 for the iOS platform, but this target supports 12.0
The package product 'firebase-core' requires minimum platform version 13.0 for the iOS platform, but this target supports 12.0
The package product 'firebase-crashlytics' requires minimum platform version 13.0 for the iOS platform, but this target supports 12.0
The package product 'firebase-messaging' requires minimum platform version 13.0 for the iOS platform, but this target supports 12.0
Expected results
The used Firebase versions require iOS 13.0 or higher. Thus the project specifies this in the project settings.
The generated FlutterGeneratedPluginSwiftPackage/Package.swift file should use the project level minimum supported version, as defined in the project.
Perhaps the MinimumOSVersion in ios/Flutter/AppFrameworkInfo.plist is a good candidate for this.
And MacOS probably also needs to be considered.
Actual results
The build fails due to the minimum iOS version in the FlutterGeneratedPluginSwiftPackage/Package.swift being Flutter's minimum iOS version.
See the attached FlutterGeneratedPluginSwiftPackage/Package.swift for an example.
Note: The project where I reproduced this also used other dependencies in the FlutterGeneratedPluginSwiftPackage/Package.swift, but those do not seem to be related to the issue.
The culprit might be the hardcoded versions in
