Maybe you had an installation problem. Either manage to reinstall iOS or go to an AppStore if there's one close to you (which is not often the case) Or contact Apple support.

Sheer curiosity That's a pretty good reason. Hope you'll get some answer. have a good day.

You mean language of iPhone ? If so, open System Preferences on the Mac, Language and Region if cheese not listed, type on the + on the lower left corner and select Chinese From there select preferred language, either for General or for selected App.

The way I do it is to design the report as a view in code. Schematically, it will be: I create a PrintView and house all the drawing in the draw function class PrintView: NSView { override func draw(_ dirtyRect: NSRect) { super.draw(dirtyRect) // Drawing code here. } } Then, to print, I call (from the handler of Print menu command for instance or from a print button in a view) let aSize = NSSize(width: printInfo.paperSize.width - 20, height: totalHeight) let printView = PrintView(frame: NSRect(origin: NSPoint(x: 1, y: 10), size: aSize)) // a full page, depending on orientation and call the printPanel         let printOp = NSPrintOperation(view: printView, printInfo: printInfo)

How can I check which configuration is being used In Xcode, at the top, at left, you'll see the name of your app, with the name of a simulator or your iPhone oat its right. Click on the name of app to get a popup and select Edit scheme. Check what is the build configuration.

To learn Swift, start with 'Intro to App Development with Swift' from Apple (in the library). Very clear and didactic.

So that could well be a compatibility issue between the pod and Xcode 12.5. You'd better ask Alamofire editor. after tag 4.8.2, they removed WWAN connectivity apis Where did you read this ? Unfortunately, that means that you will have to adapt your app anytime soon.

As OOPer stated, URL components is the safest. Otherwise, you could add manually: declare dataUrl as var and dataUrl = dataUrl.replacingOccurrences(of: " ", with: "%20") But components is safer way to go.

Did you try to unregister the device on Xcode and register again ?

In fact, X and Xs were already gone in Xcode 12.4. But don't forget that preview is just a helper. Your app should work and look good on any device.

A suggestion. Instead of the func, you could define String extension, with a property or a func extension String { var localized: String { NSLocalizedString(self, comment: "") } mutating func localize(comment: String = "") - String { NSLocalizedString(self, comment: comment) } } then you can call myString.localized or myString.localize() or myString.localize(comment:"Some comment") print("hello".localized) var myString = "hello you" myString = myString.localize(comment: "Some comment") // or myString = myString.localize() without comment print(myString)

Are they your own apps (ones you developed) or apps you downloaded. For the latter, what problem do you get ? For the former, did you try to update the app ? If you search on Google 'downgrade from iOS 14.5 to 14', you will find a lot of material. In any case, do a complete backup of your iPhone before, there is always a real risk to loose all your data.

writing "bla-bla-bla".localized looks ugly for my taste.  You're right, that's a question of taste. But there are already a lot like this in StringProtocol: "bla-bla-bla".localizedUppercase or "bla-bla-bla".localizedCapitalized If you need to keep your func, why not change it as: func localized(_ string: String, comment: String = "") - String { NSLocalizedString(string, comment: comment) } Doing so you can still call: cell.label.text = localized("Hello world")

Video is inaccessible. When running your code, just get a screen with show second view at top Tab 1 Un in the middle a field on the left at the middle, but quasi hidden a tab bar at bottom when I click button Which button, please be more precise I clicked on secondView only change state button which returns to the first view, just changed with Tab 1 Der in the middle Impossible to test anything.

OK, I could reproduce the crash (after deselecting I/O Keyboard Connect Hardware Keyboard). The crash seems due to the 2         switch tradingMode { } section If I comment out any of them, no more crash. If I reconnect Hardware Keyboard; no crash either. So problem is effectively caused by showing keyboard. Some conflict with the tabs ? I also get a crash if I tap on tab 2, without any keyboard. So there is a problem with tabs. I'll look further to it. I run Xcode 12.4 on MacOS 10.15.7
