I am having troubles reproducing but currently am on a m1 mac without x86_64 simulators. I tested on an IOS 12 device though and did not receive that crash. I wont have access to an intel machine until tomorrow.

Do you have this issue on iOS 13 or iOS 14 simulators?

[rlepinski]

@kofoednielsen Still cant reproduce using an intel device. Have you tried cleaning and wiping any derived data? Any chance you can share a project with me to help reproduce the issue?

[AlbrechtAndrzejewski]

@kofoednielsen If your project was an already existing project and you tried to migrate to latest Airship version, you may find an older Swift reference laying around in your Xcode project settings.

I faced the same link problem here after migrating to Airship 16+ (intel Mac, xcode version 13.1 - 13A1030d).
Removing this value from the LIBRARY_SEARCH_PATHS in the .pbxproj : "\"$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)\"", solved this link issue on my project.

In Xcode, double click the project icon in the tree, and look for library search paths in the "Build Settings" tab of PROJECT. Then click on the minus icon to remove any reference to swift-5.0 in the value list, be sure to keep "$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)".

Thank you @AlbrechtAndrzejewski for providing the fix. I am going to close this now since I am seeing less linked issues coming through. If it comes up again Ill add it to the README
