Swift App Opens on Simulator But Not on Device

问题

I've been working on my iOS app for a while, and it builds and runs fine on the simulator, but when I try to run it on my device, a few things happen:

• The app launch screen appears

• The app crashes and my Xcode output is as follows:

  dyld: Library not loaded: @rpath/libswiftCore.dylib
  Referenced from:/private/var/mobile/Containers/Bundle/Application/18932CDB-57DA-4A87-B154-45B9F3CD01D0/Up & Down - Minimalistic, Beautiful Counter.app/Up & Down - Minimalistic, Beautiful Counter
  Reason: no suitable image found.  Did find:
  /private/var/mobile/Containers/Bundle/Application/18932CDB-57DA-4A87-B154-45B9F3CD01D0/Up & Down - Minimalistic, Beautiful Counter.app/Frameworks/libswiftCore.dylib: mmap() error 1 at address=0x100110000, size=0x0015C000 segment=__TEXT in Segment::map() mapping /private/var/mobile/Containers/Bundle/Application/18932CDB-57DA-4A87-B154-45B9F3CD01D0/Up & Down - Minimalistic, Beautiful Counter.app/Frameworks/libswiftCore.dylib
  (lldb) 
  

• The following message also appears, with a few other similar errors:

  dyld`dyld_fatal_error:             Thread 1: EXC_BREAKPOINT (code=1,subcode=0x1200f5088)
  ->  0x1200f5088 <+0>: brk    #0x3
  

So I don't waste your time, I would like to warn you that I have tried to clean and build, revoke and renew certificates, delete all breakpoints, and restart both Xcode and my iPhone.

Any ideas on how to make my app run on my device? Thanks!!!

My project has Cocapods and I'm using multiple schemes. Running pod update fixed something wrong that happened during a merge and now it runs fine.
