It's relatively complex to determine in advance if a Xcode, SDK, and Deployment Target configuration is capable of running Swift. For example the following combinations do not work: * deployment target < OS X 10.9 * Xcode 6.2 and macosx10.9 SDK * Xcode 7 Beta 6 and macosx10.10 SDK Until we found out how to query Xcode for Swift support in a reliable way, the RunCMake.Swift test cases will be restricted to negative ones.
