        Hi Apple Developer,


        have some strange behavior with load simple JPG images from my Server...


        It works but:

        Start my App,load all pictutes it works...

        delete random file on my Server reload all urls this and the renamed or deleted image

        is already load done...


        my http response is 200 too but file is deleted or renamed

        my browser call the same URL and response is not found thats OK.


        have restart my App : same procedure

        clean my App: same Procedure


        reinstall :load all pictures and rename or delete it works (but is my picture renamed or delete) old picture is load,

        nut only 1times


        rename my picture on my Server reload my App the last picture is loaded again successful.


        Have no idea.


        macOS: last Update

        Xcode : 8.0 Final and 8.1b2 too



        here my code from my class


        swift and Xcode make me crazy....



        extension myObjClass {


            func downloadedImage() {


                let strurl = localDev.picPath! + self.ArtID


                let url = URL(string: strurl)


                UIApplication.shared.isNetworkActivityIndicatorVisible = true


                URLSession.shared.dataTask(with: url!, completionHandler: { (data, response, error) -> Void in


                    let resp = response as? HTTPURLResponse


                  // the url to my picture is 100% delete but response is 200 and picture is the last one after successful load

                    if(resp?.statusCode == 200) {


                        let image = UIImage(data: data!)

                            print("set Image Data")

                            self.picture = image

                            self.isPictureSet = true

                            let name = Notification.Name("reloadIsDone")

                            NotificationCenter.default.post(name: name, object: nil)




                        print("picture not found")

                        self.picture = UIImage(named: "noPic.JPG")

                        self.isPictureSet = false

                        let name = Notification.Name("reloadIsDone")








                UIApplication.shared.isNetworkActivityIndicatorVisible = false

          found this with request instead url and it works



            let request = URLRequest(url: url!, cachePolicy: .reloadIgnoringCacheData, timeoutInterval: 10)




                  UIApplication.shared.isNetworkActivityIndicatorVisible = true


                  URLSession.shared.dataTask(with: request, completionHandler: { (data, response, error) -> Void in

              I think you spotted the problem yourself: it is a cache issue.


              In the new request you force to reload cahce data, hence the file that have been deleted are no more accessible.


              Otherwise you load them from your cache.
