I have to get football game schedule via JSON and extract date of each game of one of the specific universities. I tried: let url = NSURL(string: "SCHOOL URL") let request = NSURLRequest(URL: url!) let session = NSURLSession.sharedSession() let task = session.dataTaskWithRequest(request){ (data, response, error) -> Void in do{ let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) if let schedule = jsonData["schedule"] as?

Here's how to add that file to your playground to make it accessible: Find your ".playground" file in the Finder Right click and choose "Show Package Contents" You should see "timeline.xctimeline", "contents.xcplayground", and "section-1.swift" Make a new folder called

Why do I get the error "join is unavailable: call the joinWithSeparator() " at line 16 (the last line below) when I try to run it on playground? And, how can I fix it? class Person { var firstName: String? var lastName: String? let gender = "female" func fullName() -> String { var parts: [String] = [] if let firstName = self.firstName { parts += [firstName] } if let lastName = self.lastName { parts += [lastName] } return " ".join(parts) } } The error message tells you what the problem is, and it tells you how to fix it. Read the error message! Do what the error message says! return parts

I'm new to iOS development and using Xcode and I'm having trouble getting Alamofire to work within a Playground. There's some functionality I'd like to test out for proof of concept but the library is not linked to the Playground and I've tried getting it to play nicely. I have Alamofire set up to work within an iOS (not in a Playground) project before the installation instructions in the Github Alamofire repo were recently updated. Any suggestions on how to get Alamofire to import properly in the Playground? Canucklesandwich Apple provides excellent step-by-step instruction to do so here:
