Hello there. Are you sure it's related to Wormholy? How to replicate it?

[skeyboy]

I. just. got. it from. firebase report

I'm also facing a crash in iOS 15.

I think you could reproduce it by creating a project that uses Wormholy in the latest Xcode 13 and running it against a simulator (iOS 15).

My versions:

Wormholy version: 1.6.4 (integrate via Cocoapods) Xcode version: 13.0 beta 3 (13A5192j) iOS: 15 beta 3 (19A5297e)

To me it crashes right after the app starts. Here are the relevant parts of the stack trace:

// ... inside the "CustomSelfAwareHelper.harmlessFunction"
for index in 0 ..< typeCount {
    (types[index] as? SelfAware.Type)?.awake() // LLDB says it crashes exactly in the "as?" part of the function, with a "Thread 1: EXC_BAD_ACCESS" exception
}

static CustomSelfAwareHelper.harmlessFunction()

0x111e33951 <+81>:  callq  0x111e33a00               ; function signature specialization <Arg[0] = Dead> of static Wormholy.CustomSelfAwareHelper.harmlessFunction() -> () at SwiftySelfAwareHelper.swift:18

0x129775e0b <+101>: leaq   0x7fdcfa(%rip), %rdi      ; "Application violated contract by causing UIApplicationMain() to return. This incident will be reported."

If I remove Wormhly, the app doesn't crash anymore.

Let me know if more info is needed, thanks.

Oh, and finally: it crashes when building for Release; (Xcode / Edit scheme / Run / Info / Build configuration / Release)

We weren't facing it during development as we were installing the app via Xcode in debug mode; QA was facing it in TestFlight builds (release mode).

You may not be able to reproduce w/o using Release mode.

Very tricky.

We also have got a crash on production build related to WormholyReplaceMethod call on iOS 15 beta.

Possibly got the same crash, app works fine on iOS 14.x, but crashes on iOS 15b3. We only use Wormholy for debug builds. The project is built with Xcode 12.5.1
