Xcode 7 or 8 issue with Pods, can't run at all

Getting this error for pods in Xcode when trying to run app:

error: A cryptographic verification failure has occurred.

  • Tried reinstalling Pods/repo
  • Reinstalling Xcode(s)
  • Also doesn't run on simulators:

DTAssetProviderService could not start DTXConnection with Simulator

Also, running Sierra at the moment (yes, I know).

This is a regression in macOS Sierra that multiple developers have reported in the forums and in the lab sessions at WWDC. Xcode 7.3 is not officially supported on Sierra. If you want to use macOS Sierra, please use Xcode 8.0 beta or later.

If you must use Xcode 7.3 on Sierra, you can partially workaround this bug by using Xcode.app to install the app through Build & Run, launch the app suspended from the command line (xcrun simctl launch -w booted <app identifier>) and then attach with the debugger and resume the suspended process.

Note that this issue only impact Xcode 7.3.1 downloaded from the Mac App Store. You will not hit this issue if you use Xcode downloaded from http://developer.apple.com (ie, the "drag & drop installer"). Note that you might hit another issue with the same symptoms when using the drag & drop installer. That is discussed in DTAssetProviderService could not start DTXConnection with Simulator
