Relevant log output

[kubaflo]

Your repo works for me - no crash. Maybe try to remove the bin and obj folders and restore the solution?

[mshenoy83]

@kubaflo are u on XCode 16.4? I was on XCode 16.3 till last week and it was all good. But once I updated dotnet and XCode this started happening. I also tried from my work mac which has XCode 16.2 and dotnet 9.0.201 and it works absolutely fine

[mshenoy83]

Theres another guy who is facing the same issue dotnet/maui#30098. Please try by updating to latest XCode and latest dotnet version.

[bhuwancb99]

Hi @jfversluis – I am using the latest version of Xcode and the latest .NET framework, but the app crashes after installation on a device running version 15.8.4.

[19521769]

I'm experiencing the same bug as you. It works fine on iOS 16 and above, but the issue only happens on iOS 15

[bhuwancb99]

Yes , above iOS 16 and above it's working but below iOS 16 is not working and app crashed multiple places like click on tab bar or any button click

[mshenoy83]

The issue is with ios 18.5 and latest dotnet release SDK 9.0.301. I've mentioned that I installed XCode 16.4

This is a regression in our iOS SDK, I'll have a look.
