So as I found out that that old iPhone I have doesn't upgrade beyond 12.x and teh Apple Sign in requires 13.x or higher , I thought using a simulator might do teh trick .
First I tried the Unity one, but that just seems to use an overlay and doesn't seem to be simulating the OS I need to test.
Unfortunately the xCode simulator produces a black screen upon loading the startscreen and seems to crash or stop loading.
I wanted to upload an image but this forum gives errors and doesn't allow gdrive links so I am just going to paste the console stuff:
libsystem_pthread.dylib`thread_start: 0x7ff834c38f5c <+0>: pushq $0x0 0x7ff834c38f5e <+2>: pushq %rbp 0x7ff834c38f5f <+3>: movq %rsp, %rbp 0x7ff834c38f62 <+6>: subq $0x10, %rsp 0x7ff834c38f66 <+10>: callq 0x7ff834c3d464 ; _pthread_start **-> 0x7ff834c38f6b <+15>: leave produces this error ===> Job.Worker 0 (14): EXC_BAD_ACCESS (code=2, address=0x1439c1000) ** 0x7ff834c38f6c <+16>: retq 0x7ff834c38f6d <+17>: nopl (%rax)
and this is in teh below part of the console thingy:
Funnily enough the game works fine on the iphone 6, but not on the simulator ...probably have to buy another apple device against my will to test, but I hope someone knows how to just get apple sign in to work and test it on a simulated device in an Unity (2012) and Xcode workflow (14)
