Also tested with all versions from 14.0.0 and they all crash when trying to present the Messenger.

It crashes even when launched from the Intercom launcher.

Note: the view controllers are loaded from individual XIB files and not from a storyboard.

 

The SDK was installed through Swift SPM.

 

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '9<IntercomSDKPrivate.HomeHeaderViewController 0x11df35780> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key chatButton.'

 

The weird thing is that we don't have a HomeHeaderViewController but our button is named 'chatButton' from where we launch intercom. If I rename chatButton to 'helpButton' the message will change to:

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '&<IntercomSDKPrivate.HomeHeaderViewController 0x109bd9d80> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key helpButton.'

Is there something that I need to do differently? If I use: Intercom.present(.messages) it does not crash..

 

The same happens also on iOS 15.5:
