Error: Expected member name or constructor call after you type name.

I get this error: "Expected member name or constructor call after you type name." when I put the code in from the teacher's notes: NSString(contentsOfURL: NSURL, encoding: UInt, error: NSErrorPointer). I did what Xcode recommended me to do but it doesn't return what it's supposed to.

Any help would be appreciated! Thanks!

Rolando,

Are you trying to print the JSON contents to the console?

NSString(contentsOfURL: NSURL, encoding: UInt, error: NSErrorPointer) is the formatting guideline. It's not functioning code. For NSURL, you need something that is an actual URL. For the encoding, you need to specify the type of encoding to expect. Same goes for the error.

So, if you're going to print the JSON data to the console like Pasan does in the video, you would put something like this:

// See the JSON data in the console
var urlContents = NSString(contentsOfURL: location, encoding: NSUTF8StringEncoding, error: nil)
println(urlContents)

location is a variable storing the contents of the JSON weather URL.

I'm sure someone can more eloquently explain this.
