NSURLSession completion block not called

Question

var session = NSURLSession.sharedSession()
session.dataTaskWithRequest(urlRequest, 
                            completionHandler: {(data: NSData!, 
                             


        

Answer 1

I face the same problem and I solved it by

NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * data, NSURLResponse * response, NSError * error) {

    if (!error)
    {
        NSLog(@"Data is %@",data);
        NSLog(@"Response is %@",response);
        NSLog(@"Error is %@",error);
    }
 }];

[dataTask resume];

And check that you are added the App Transport Security Settings in your info.plist.
