My situation and environment is as below:

XCode 16.2,macOS Sequoia 15.2, flutter 3.7.12 Swift 5, mini os iOS 12.0

I used the commands of “flutter clean” and “flutter pub get” and cd to ios folder and run “pod install”.

I opened Xcode to archive ipa file appear a problem as below:

Disabling previews because SWIFT_VERSION is set and SWIFT_OPTIMIZATION_LEVEL=-O, expected -Onone

Solution: In the file of Runner/Flutter/Release.xcconfig in Xcode, add the code as below:

ENABLE_PREVIEWS = NO

And then Clean Build Folder and archive again. The problem will be solved.
