Use this tag for questions related to teaching the Swift programming language from Apple. More generally it may be applied to questions of developing IOS applications in Swift.
Swift is a programming language created by Apple Computer, primarily for building mobile applications for the IOS operating system. Use this tag for questions about teaching Swift, but not for technical questions about the language itself.
Likewise, since Swift is used primarily for IOS application development, use the tag for teaching such development using Swift. It is not appropriate for technical questions about IOS or IOS development. Those questions are appropriate in other fora on Stack Exchange.
