Crash on iOS 17.4 simulator

[Etheonor]

Hello,

I have an issue with flutter-maplibre. It was working fine on the simulator and today I was asked to update my iOS version to 17.4 I now have a crash each time I try to display the map. It still works fine on Android.

Here is the crash log:

I can't test on my iPhone I need to create my Apple dev account before. But if you have an idea of what's going on here, don't hesitate to tell me if I did something wrong!

I can confirm it only happened with iOS 17.4, I reinstalled a 17.2 simulator and everything's fine...

[Camerash]

+1 on this, experiencing this as well!

Thanks for sharing, has anyone seen this on a real device as well?

On my side it work on real devices. It crashes only on iOS simulator, under iOS 17.4

[m0nac0]

There are reports upstream in the maplibre-native repo (maplibre/maplibre-native#2189) of the iOS 17.4 simulator crashing with the 5.x.x version of the MapLibre iOS SDK, which we are using at the moment. So this is likely an issue with the OpenGL simulation in the iOS 17.4 simulator, but should not impact real devices.

Workaround is using any other (lower) simulator version. A fix would be transiting to use v6.x of the MapLibre iOS SDK (see #389)

[Etheonor]

Thanks you!

Yep as a workaround I'm now using a 17.2 simulator. My biggest problem would have been to see that this was also the case on a real device, but since you confirm that it isn't, it's not necessarily a big deal!
