This is my first proposal to swift-corelibs, so I’m not sure how much
flexibility we have in terms of deviating from the darwin’s original Foundation
definitions. That said, it’s always seemed a little screwy to me that NSTask's
standardInput/standardOutput/standardError properties sacrifice any semblance
of compile-time type safety by accepting id/AnyObject (which, at run time, must
be either NSPipe or NSFileHandle, else it blows up). If allowed, I’d like to
take the opportunity to modernize this in the open source version of Foundation.
public class NSTask : NSObject {
...
public enum IOType {
case FileHandle(NSFileHandle)
case Pipe(NSPipe)
}
public var standardInput: NSTask.IOType?
public var standardOutput: NSTask.IOType?
public var standardError: NSTask.IOType?
...
}
