Unexpected Mach-O header code when archiving an iOS Audiokit project

I have an iOS AudioKit project that builds and runs in the simulator and physical device, but when I archive and then validate throws the error:

"Found an unexpected Mach-O header code: 0x72613c21"

In the critical log it states:

2018-07-11 20:05:58 +0000  Failed to generate distribution items with error: Error Domain=DVTMachOErrorDomain Code=0 "Found an unexpected Mach-O header code: 0x72613c21" UserInfo={NSLocalizedDescription=Found an unexpected Mach-O header code: 0x72613c21, NSLocalizedRecoverySuggestion=}

I've tried deleting derived data folder and reinstalling frameworks.

Running xCode 9.4.1 Audiokit 4.2.2

Solution

I don't think this is AudioKit related per se as we've been archiving AudioKit powered apps nearly daily for a while now. What's most likely happening is that you're treating AudioKit like a dynamic framework even though it is a static one. That might survive local installs but then archive would complain.
