        Does anybody see what's wrong? I have this type of crash (Crashed: com.apple.main-thread SIGABRT ABORT 0x000000018f2c82ec) and I don't see why it crashes in init method of UIActivityIndicatorView.
        I don't understand how it's possible to crash in the init method in general.

        The problem is that I am not able to reproduce it, but it happens to random users.

        Thank you in advance for any help

          This is definitely a memory management problem.  Looking at your backtrace, frames 3 through 0 indicate that the memory allocator killed your process because it detected memory corruption.  My recommendation is that you apply the Standard Memory Debugging Tools to see if you can trigger it in your office.
