Document Xcode's interactions with push
We need to document how to resolve debug issues for Xcode with Push, this includes:
- [ ] Creating a support article
- [ ] Writing up information for relevant docs
- [ ] Dashboard interfaces need useful info
Notes:
Check if the app has Push Notifications well configured in the Apple Developer account: 
Go to the target settings > Capabilities > Push Notifications and check if all steps are ok: 
Check if the correct certificate is in place in Ably Dashboard.
In Xcode, you can't use production certificate in debug/development.
From oficial documentation:
Xcode sets the value of the entitlement based on your app's current provisioning profile. For example, if you're using a development provisioning profile, Xcode sets the value to development. https://developer.apple.com/documentation/bundleresources/entitlements/aps-environment?language=objc The easiest way to test production notifications (without releasing the build) is installing the app via TestFlight. Just archive and upload a build and enable internal testing after the build has finished processing in AppStore Connect. Then just install that build in your device.
