I tried to create a UILabel in playground but failed. Does playground only support OS X development for now? YES, it does! File: New > File... > iOS > Source > Playground import UIKit let lbl = UILabel(frame: CGRectMake(0, 0, 300, 100)) lbl.text = "Hello StackOverflow!" Then, save the file.

I had been referring to earlier Xcode Playgrounds as an interpreter, but would one still consider
