I am trying to troubleshoot an issue that surfaced recently that I am having difficulty fixing as it is only happening on the exported (Archived) releases of my app. Error in crash log is Namespace SIGNAL, code 4, Illegal Instruction 4 My project uses a cocoapod to work with hardware devices and this error happens only for specific device and only on client machines. For testing, my Xcode dev machine and my test machine are both Macbook Pros running 12.6. Before testing, I delete the old app completely, remove any privacy entries, and preferences files, caches etc. When I first install the app (No installer, just coping .app file), the app launches and it doesn't throw the error and works. If I close the app and reopen, as soon as I try to use the device, app crashes. I use a different hardware device and there are no issues.

For some reason, the following function in the delegate: func session(_ session: SHSession, didNotFindMatchFor signature: SHSignature, error: Error?) { DispatchQueue.main.async { print(match error: (String(describing: error))) } } always prints: match error: Optional(Error Domain=com.apple.ShazamKit Code=202 Please check that you have enabled the ShazamKit App Service for this app identifier UserInfo={NSDebugDescription=Please check that you have enabled the ShazamKit App Service for this app identifier}) What can I do to fix that? The complete code for the app is available on my GitHub. Edit: just wanted to add that I'm using Xcode 13.0 Beta 1, on macOS Big Sur 11.4
