[SOLVED] Publishing Flutter iOS App using Beta OS

Download released xcode version from AppStore

At this point, you will have 2 XCode app, one is beta and one is released, the released version however cant be open

Check xcode-select path with xcode-select -p and Switch to released path if its on beta like so:

xcode-select -s /Applications/Xcode.app/Contents/Developer

Build IPA file with flutter build ipa

Now, open the archive package content and open the Info.plist file at

Products/Applications/Runner -> Show Package Contents -> Info.plist

Now, change BuildMachineOSBuild version to latest released MacOS version check it here: https://en.wikipedia.org/wiki/MacOS_version_history

Saved the file then Distrubte the App by opening the archiver file.

Should be fix.
