Swift 3 let original = “http://www.geonames.org/search.html?q=Aïn+Béïda+Algeria&country=” if let encoded = original.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed), let url = URL(string: encoded) { print(url) }

Swift: How do I return a value within an asynchronous urlsession function?

by

You should add your own completionHandler closure parameter and call it when the task completes: func googleDuration(origin: String, destination: String, completionHandler: (Int?, NSError?) -> Void ) -> NSURLSessionTask { // do calculations origin and destiantion with google distance matrix api let originFix = origin.stringByReplacingOccurrencesOfString(” “, withString: “+”, options: NSStringCompareOptions.LiteralSearch, range: nil); let destinationFix = destination.stringByReplacingOccurrencesOfString(” … Read more

How To Download Multiple Files Sequentially using NSURLSession downloadTask in Swift

by

Your code won’t work because URLSessionDownloadTask runs asynchronously. Thus the BlockOperation completes before the download is done and therefore while the operations fire off sequentially, the download tasks will continue asynchronously and in parallel. While there are work-arounds one can contemplate (e.g., recursive patterns initiating one request after the prior one finishes, non-zero semaphore pattern … Read more

We were having issues connecting to Amazon S3 URLs that appeared to be perfectly valid, TLSv12 HTTPS URLs. Turns out we had to disable NSExceptionRequiresForwardSecrecy to enable another handful … Read more

How do I make an HTTP request in Swift?

You can use URL, URLRequest and URLSession or NSURLConnection as you’d normally do in Objective-C. Note that for iOS 7.0 and later, URLSession is preferred. Using URLSession Initialize a URL object and a URLSessionDataTask from URLSession. Then run the task with resume(). let url = URL(string: “http://www.stackoverflow.com”)! let task = URLSession.shared.dataTask(with: url) {(data, response, error) … Read more

How can I get the Data from NSURLSession.sharedSession().dataTaskWithRequest

by

You can’t return data directly from an asynchronous task. The solution with Swift 2 is to make a completion handler like this: class PostFOrData { // the completion closure signature is (NSString) -> () func forData(completion: (NSString) -> ()) { if let url = NSURL(string: “http://210.61.209.194:8088/SmarttvWebServiceTopmsoApi/GetReadlist”) { let request = NSMutableURLRequest( URL: url) request.HTTPMethod = … Read more
