| Not surprisingly, Xcode is able to autocomplete the parameters to the separate function.
Here’s my whole routine:
override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib.
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config)
let request = NSURLRequest(URL: url!)
var task = session.dataTaskWithRequest(request) { data, response, error in
let httpResponse = response as! NSHTTPURLResponse
if httpResponse.statusCode == 200 {
let teams: AnyObject? = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments, error: nil)
println(teams) }
} task.resume()
}
Paste this into a new project, and click after the “in” and see if Xcode recognizes “data”, “response”, or “error” when you start typing. Oddly, after you enter the keyword, you can option-click to have Xcode show you the correct type, and typing a “.” will give you the autocomplete popup.
Thanks.
Hello...
There doesn’t seem to be anything wrong with your line of code, but there could be a problem somewhere else (or with how/where you’re writing the code for the completion handler block).
I’ve run into problems a few times where the compiler didn’t report errors properly or gave cryptic error messages, but I was usually able to figure out my mistake by breaking out the offending line into individual statements so that I got a better error message from the compiler (except for one time, where a mistake in declaring a function compiled cleanly and then later on segfaulted the compiler when it was called; 19437380).
To isolate the problem, I’d try declaring the completion handler function separately and then pass in the function.
func testHandler(myData: NSData!, myResponse: NSURLResponse!, myError: NSError!) -> Void // try your handler code here let task = session.dataTaskWithRequest(request, completionHandler: testHandler)
If Xcode accepts your handler code that way and accepts the function as a parameter, you might have a mistake in how you’re adding your handler code to the inline closure in the line you posted. If you post the code showing how you are adding the handler code to the original line you posted, we could rule that out.
