Unrecognized availability platforms (AvailabilityUnrecognizedName)

Warnings that identify unrecognized platform names in @available attributes and if #available statements.

Overview

The AvailabilityUnrecognizedName group covers warnings emitted when the platform name specified in an availability related construct is unrecognized by the compiler:

@available(NotAValidPlatform, introduced: 1.0) // warning: unrecognized platform name 'NotAValidPlatform'
public func function() {
  if #available(NotAValidPlatform 2.0, *) { // warning: unrecognized platform name 'NotAValidPlatform'
    // ...
  }
}

Availability specifications with unrecognized platform names in @available attributes and #available queries are ignored by the compiler.
