As far as the black screen goes...

Usually when there's a blank screen at launch that means that Kodi is either crashing at launch or that there is an issue with code signing (which would cause Kodi to crash)

My suggestion would be to try and re-sign Kodi with iOS App Signer and then re-install right over the top of the existing app (don't remove from Xcode)

If that doesn't work, delete Kodi from your device and re-install...

Yes, you'll lose the Kodi settings and add-ons...

Unfortunately when this happens there isn't too much that can be done...

If that still doesn't work, there's one last thing you can try...

• Delete the Apple ID from the Xcode preferences
  
• Go into keychain and delete the iPhone Developer certificates
  
• Go to ~/Library/MobileDevice/Provisioning Profiles (Use Command+Shift+G in finder) and delete the files inside that folder
  
• Add the Apple ID back into Xcode and repeat the signing process from step 1
  

This is more of a last resort but it will most likely fix any signing issues...

Of course this isn't very practical if you're a developer with apps signed using the certificates...

But, if you're having issues with iOS App Signer and the certificate you shouldn't be able to launch any app made with Xcode either...
