What are the implications of disabling swizzling?

Hey Tom,

If you experience a crash containing swift_getSingletonMetadata in the stack trace, it may be caused by a potential bug in Swift.

This happens when one of your classes class references another class in a framework on an iOS version lower than the minimum required version of that framework.

Disabling swizzling will remedy the above crash.

However, we use swizzling to automatically configure Push Notifications. If you disable swizzling, you’ll need to manually configure Push Notifications. oYou can do this by following the steps in our documentation here](https://developers.intercom.com/installing-intercom/ios/push-notifications#manually).

We don’t recommend disabling swizzling unless you’re specifically encountering the swizzling-related crash described above. Hope this helps!
