My app is hanging on launch, I’ve turned on hang logging on the phone and have extracted a hang file (.ips file).
I want to find out what method from the app is referenced here:
595 start + 2240 (dyld + 23940) [0x1c6e14d84]
595 ??? (MyApp + 67912) [0x10204c948]
595 UIApplicationMain + 340 (UIKitCore + 2273848) [0x1a513e238]
So I’m trying to use the atos command to symbolicate it:
atos -arch arm64 -o MyApp.dSYM/Contents/Resources/DWARF/MyApp -l
<what is the load address> 0x10204c948
But I don’t know what to use for the load address. The Apple instructions for atos show how to find the load address from a .crash file, is it possible to find it from the .ips file?
