The memory used jumps to 498 megs when image is loaded but not displayed and drops to 242 megs when viewcontroller is dropped with nav controllers back button. UIImage(contentsOfFile: is not supposed to cache, i assume that is where the 240 meg drop is from, but why is half of memory used, 240 megs, being retained? func  save_ImageJPG() -> Bool {         // load tif from app folder image approx 8000 x 6000 pixels         let s  = currentMap_Name.replacingOccurrences(of: " ", with: "%20")         let filePath = getDocumentsDirectory().appendingPathComponent("Folder" ).appendingPathComponent(s)         let image = UIImage(contentsOfFile: filePath.path)         // change file type to jpg         let f = URL(string: s)?.deletingPathExtension().absoluteString         let e = URL(string: f! + ".jpg")?.absoluteString         let path = getDocumentsDirectory().appendingPathComponent("TempFolder"         ).appendingPathComponent(e!)         if !FileManager.default.fileExists(atPath: path.path) {             let jpgData = (image!.jpegData(compressionQuality: 1.0)!)             try? jpgData.write(to: path)             return true         }             return false     } or is the let jpgData = (image!.jpegData(compressionQuality: 1.0)!) retaining memory?

I am downloading image files which are in the zip format to a folder in my app files folder. When the folder is opened the file is shown as .zip and when selected it unzips and creates a new file. In my case it creates a jpg. leaving the zip file also. My question is, how do I unzip the file with swift since iOS appears to have the capability?

This is a simple test file sharing which I cannot find info on. the "(This will become a fault soon.)" from xcode is what is the worrisome, it seems to have developed recently with xcode update? I don't want to release an app which may soon fail. class ShareFile_ViewController: UIViewController {     override func viewDidLoad() {       super.viewDidLoad()             navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Share", style: .plain, target: self, action: #selector(shareFile))         }        @objc func shareFile() {             if let fileURL = Bundle.main.url(forResource: "Skiing", withExtension: "gpx") { let ac = UIActivityViewController(activityItems: [fileURL], applicationActivities: nil) present(ac, animated: true, completion: nil)             }        } } // this error has been beat to death as don't worry about it. 2022-02-19 16:28:47.644274-0800 ShareFile_Learn[36671:12674168] [db] Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=264, _LSFunction=-[_LSDReadClient getServerStoreWithCompletionHandler:]} // this warning is my concern since it says it become a fault soon, should I worry about this? 2022-02-19 16:28:47.644370-0800 ShareFile_Learn[36671:12674168] [default] -imageForImageDescriptor: can do IO please adopt -imageForDescriptor: for IO free drawing or -prepareImageForDescriptor: if IO is allowed.

Why, when I open an Tiff image in an UIImage I get memory leaks? Leaks shows "+0xd0 cbz                 x0, "TIFFReadPlugin::DecodeBlockTiled(IIOImageReadSession*, GlobalTIFFInfo*, ReadPluginData const&, TIFFPluginData const&, IIODecodeFrameParams&)+0x94c" Anyone have an idea?

my iphone app downloads maps from a website which uses the following for the download link. col3 recImageMini lazy" style="background-image: url(/img4/usTopo_icons/Browse/ID/ID_Oden_Bay_20200415_TM_tn.jpg); Apparently fetch won't let my app download without the http(s) prefix. How can the link be captured so I can add a http prefix? The links work okay when using a browser on iPad/phone/imac but not when using WKWebkit. Thanks
