I've looked at a bunch of answers here and none have fixed my issue.

I have an Xcode workspace with a custom framework and an iOS app project. The project has been working fine until this morning, now it builds but immediately crashes:

dyld: Library not loaded: @rpath/ONCKit.framework/ONCKit
  Referenced from: /private/var/mobile/Containers/Bundle/Application/4DF67A3F-6255-4276-8812-8C742A363995/atero_t.app/atero_t
  Reason: no suitable image found.  Did find:

I've been experimenting with build settings all day and I'm just totally lost.

I came across this issue today and resolved it the same way. Revoke and regenerate code signing solves this issue. But to shed some light on the "why" part of it.

Apple went ahead and changed the certificate contents. To be more precise, it added a new "OU" (organizational unit) field under Subject. By revoking and regenerating the code signing, it added the missing field and the problems went away.
