Hi, my name is Danilo and I work in a IT Company in Brazil.

We have a client that uses an app based o OBJECTIVE-C, and after the iOS 15.0 update, the app started to crash just by clicking anywhere... we need help.

I'm going to leave here some log that got generated.

Any help would me great. Thanks a lot !

Using the iPad mini (6th generation) is a complication here, as it uses a different (smaller) screen size than any previous iPad.
Could it be that your code does not take account of this?

Do you get the same crash on a "normal" (or larger) iPad?

There are a lot of references to "simulator" in that log. For example r/CoreSimulator/Profiles/Runtimes/iOS.simruntime and Build/Products/Debug-iphonesimulator.

Did he somehow get a build for the simulator instead of an actual device?

Does then new iOS 15.0 interfere on a Objective-C based app?

Just to be clear, iOS 15 fully supports apps built with Objective-C. It’s likely that your app has a general compatibility issue that’s unrelated to its Objective-C-ness.

but it crashes in the physicial device

That should generate a crash report. Please post it here.

See Posting a Crash Report for advice on how to do that.

Thread 57: "Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread."

-[UINavigationController initWithRootViewController:] must be used from main thread only

This has been the error
