swift - How to run an iOS app that causes runtime error for frameworks "code signature invalid"

Question

Every time I try to run this application it builds OK and installs, but as soon as it runs, the application breaks and prints this error message:

dyld: Library not loaded: @rpath/StandardCyborgFusion.framework/StandardCyborgFusion
  Referenced from: /private/var/containers/Bundle/Application/2292CCF2-800F-4E28-AF10-A1B98081DD0A/StandardCyborgExample.app/StandardCyborgExample
  Reason: no suitable image found.  Did find:
    /private/var/containers/Bundle/Application/2292CCF2-800F-4E28-AF10-A1B98081DD0A/StandardCyborgExample.app/Frameworks/StandardCyborgFusion.framework/StandardCyborgFusion: code signature invalid for '/private/var/containers/Bundle/Application/2292CCF2-800F-4E28-AF10-A1B98081DD0A/StandardCyborgExample.app/Frameworks/StandardCyborgFusion.framework/StandardCyborgFusion'

I saw many similar posts here and on the App Developer forums about this problem but no one has an explanation or a valid fix.

I tried:

• Cleaning and building
• Restarting XCode
• Restarting the Mac
• Completely resetting Keychain
• Verifying all Keychain certs Trust settings are on "Use System Defaults"
• Factory resetting my Mac

It appears to be an issue with my iOS device. The application can start on a simulator, but the simulator is not good for my development purposes so I need to make this work on my device. I recently updated my iPhone XR to iOS 13.3.1.

"Running new app on actual iOS (13.3.1) device crashes on startup: code signature invalid for "path/to/Flutter.framework/Flutter" #49504" seems to be the same issue.

I'm using XCode 11 and iOS 13.

Answer 1

I'm using CocoaPods, and for me this fixes the error (Wasa22's Answer on github issue):

1. Open the podfile
2. Comment out use_frameworks!
3. Add use_modular_headers!
4. In Terminal, do a pod update -> pod install
5. In Xcode, Clean (Command-Shift-K) -> Build and Run.
