Same for me. Runs fine in the iPhone simulator though.

The app appears to get installed (the icon appears in the launcher), but when I tap it it shows the launch image then crashes back to the launcher, printing the following message in the Flutter debug console:

[FATAL:flutter/shell/platform/darwin/common/availability_version_check.cc(39)] Check failed: AvailabilityVersionCheck.

My development iPod is quite old and running iOS version 12.5.5 (I notice you are running iOS 12.5.7, @JacoFourie ). I suspect the minimum required iOS version has been bumped up and we're just out of luck :-(

@vashworth Is there a version compatibility matrix we can link to?

This link states 11 - 15 is best effort, so it should still work. It was not in the breaking changes list. The iPhone 6 still runs my app fine so it should not be excluded from the OS versions.

Xcode 15 does not support iOS 11 (see fluttercommunity/plus_plugins#2169)

I had the same issue, but fixed it by bumping the deployment target to iOS 12 in the podfile, and cleaning and rebuilding the project. (https://stackoverflow.com/a/64075795/13031778 but use iOS 12)

edit: this does not seem to be a fix for this issue. I thought i fixed it, but it seems like its still failing.

[vashworth]

I'm not very familiar with this availability check, but Xcode 15.0.1 should still support iOS 12 (https://developer.apple.com/support/xcode/). I don't get this error when I run with an iOS 14 simulator or iOS 16.7.2 physical device

Seems like this availability version check was added in flutter/engine#44711. @zanderso Do you have any insight into why this would error for iOS 12?

[zanderso]

I suspect that #138711 (comment) is the answer here.

The availability check implementation added in flutter/engine#44711 was copied from clang's implementation from its iOS runtime library prior to an ABI breaking change to clang, which allowed Flutter to roll clang forward across the ABI break. Which is to say, the failures on iOS 12 in this issue and #135317 would be happening even without flutter/engine#44711 and leaving clang pinned to the old version.

Well this is obviously not the case as my device is iOS 12

3.16 also has the same problem

[nakhunchumpolsathien]

3.16 also has the same problem

[juliansteenbakker]

It seems that my previous answer is incorrect. All of my other projects are failing on iOS 12 with Flutter 3.16 on this error, also on the Beta channel. I think this should have the highest priority right now since this is a stable release which breaks iOS 12.
