conversions.");

"The version of Apple Xcode installed on the remote Mac OS X host is prior to 7.1. It is, therefore, affected by a
vulnerability in Swift-based programs due to unexpected values being returned for certain type conversions. An
unauthenticated, remote attacker can exploit this, by manipulating return values, to circumvent controls in program
logic.");
