EXC_BAD_ACCESS for URLForUbiquityContainerIdentifier

The following line always causes a crash under iOS 13:
[[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];

The error EXC_BAD_ACCESS (code=2, address=0x....)


It happens for me only?


I've tested ше on an iOS 12 device - works fine, no crash.
