I develop an App which has a quicklook preview for files located on a web server To realize this preview, I download the file and access it with a QLPreviewController When I use simulator, I can see the downloaded files somewhere in library/developper/coresimulator..... and so on of my mac, and I can manually delete them. But if I search these files on the IPhone simulator, I can't find them. What when I run the application on my real device? How will I be able to delete these files? because I think it take place in the IPhone

For some programming reason, I need to know the real size (width and height) of an UIView wich has constraints. Depending on the device I use, and depending on the orientation of the device, the width or height of my view change, but frame and layer frame don't give me the correct result. Is there a mean to have the size?

I'm complety lost with async await operation I have a subclass of UITextField which provide a verif method in the resignFirstResponder method, I call the verif Method and return true or false, depending of the result of the verif the verif method is asynchrone, because it can make call to a web server. My code is: import UIKit public enum VerifResult<S: NSString> { case success case failure(S) } @IBDesignable class TextField: UITextField { @IBInspectable var obligatoire: Bool = false override func resignFirstResponder() -> Bool { var bRes = false do { let res = try await withCheckedThrowingContinuation { continuation in let result = try await verif() continuation.resume(returning: result) } switch res { case .success: bRes = true case .failure(let msg): bRes = false } } catch { return false } return bRes } public func verif() async throws -> VerifResult<NSString> { if obligatoire && text == "" { return .failure("Zone obligatoire") } else { // make call to a webserver and return .sucess or .failure return .success } } } in the resignFirstResponder on the line try await, the compiler detects the error: Invalid conversion from throwing function of type '(CheckedContinuation<_, Error>) async throws -> Void' to non-throwing function type '(CheckedContinuation<T, Error>) -> Void' I'm lost, I don't understand why where is my mistake?
