Skipped declarations

5 declarations were excluded from these bindings. Each reason comes from the generator or the iOS SDK compiler.

MFMessageComposeViewController.message

The iOS SDK compiler rejected this binding: reference to member 'message' cannot be resolved without a contextual type

MFMessageComposeViewController.message

The iOS SDK compiler rejected this binding: value of type 'MFMessageComposeViewController' has no member 'message'

NotificationCenter.MessageIdentifier.textMessageAvailabilityDidChange

Static protocol requirements cannot be called through an instance.

MFMailDraft.init()

inherited init: cannot prove legal (class declares 1 custom initializer)

MFComposeAssistantViewController.init()

inherited init: cannot prove legal (class declares 1 custom initializer)
