In Xcode playground, control the string representation in the right side column?

Question

I thought the Printable protocol would do it, but it doesn't. Is there another protocol? I want it to show the 3 numbers, not "C._GLKVector3"

There's a `DebugPrintable` protocol. Perhaps try that? – nhgrif Apr 27 '15 at 00:11 — nhgrif, Apr 27 '15 at 00:11
Your right. I just tried it as well. – nhgrif Apr 27 '15 at 00:19 — nhgrif, Apr 27 '15 at 00:19

As of Swift 2 this can be done by making the type conform to CustomStringConvertible (previously Printable). In the case of GLKVector3 you would do:

extension GLKVector3: CustomStringConvertible {
    public var description: String {
        return "<\(x), \(y), \(z)>"
    }
}

Try import XCPlayground there is something for that. Here is everything from that modul: https://developer.apple.com/library/mac/documentation/Swift/Reference/Playground_Ref/Chapters/XCPlayground.html
