I need help debugging an issue where the app I am developing crashes on start-up about once every five or six times I start it. The line of code that crashes is this: page[pageToSet].parameter[parameterToSet].source = source both the [parameterToSet].source and local "source" variable are defined as Strings and the value of "source" is "i ". This should be fine, yet, it crashes. I followed xCode's recommendation to, "set a breakpoint in malloc_error_break to debug" and the next time my app crashed it reported: libsystem_malloc.dylib`malloc_error_break: ->  0x19d215cd8 <+0>:  pacibsp      0x19d215cdc <+4>:  stp    x29, x30, [sp, #-0x10]!     0x19d215ce0 <+8>:  mov    x29, sp     0x19d215ce4 <+12>: nop         0x19d215ce8 <+16>: ldp    x29, x30, [sp], #0x10     0x19d215cec <+20>: retab Which is gibberish to me... Help?

Installed iOS 15.5 on my iPhone and Xcode 13.4.1 today...rebooted computer. No worky on iPhone. Works with iPad running 15.4.1. Ideas? PS - since posting this, I rebooted my iPhone also and now it works. Hopefully this post helps someone else!
