Hi, I'm testing one of my app on iOS 14 with Xcode 12 beta 3 (12A8169g) and I have a problem with my storyboards. Xcode give me this error for all the storyboards that contain a split view controller: An internal error occurred. Editing functionality may be limited. The log generated by the Xcode "Report a bug" button say: Exception name: NSInvalidArgumentException Exception reason: UITabBarController is unsupported as viewController for -[UISplitViewController setViewController:forColumn:] in Primary column It worked correctly on Xcode 12 beta 2. Has anyone encountered the same problem and found a way to fix it? Thank you

I have a ZStack with two nested views. They are both the same type, RowView, and each RowView has another ZStack and a Text. Both of these RowViews have the same height for some reason. And when I replace the RowView ZStack with just a Text, it works correctly. import SwiftUI struct ContentView: View {     var body: some View {         ScrollView { 		 // remove this ZStack and things work with the other nested ZStacks             ZStack {                 Rectangle()                     .foregroundColor(.blue)                     .shadow(radius: 5, x: 5, y: 5)                                  VStack {                     // Two independent RowViews:                                          RowView(title: "Some really long text for some stuff lollola really long text for some stuff lollola")                                          RowView(title: "and more")                 }             }             .padding()         }     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView()     } } struct RowView: View {     @State var title: String          let boxSize: CGFloat = 40          var body: some View {         HStack(alignment: .top, spacing: nil) {             Rectangle()                 .foregroundColor(.orange)                 .frame(minWidth: boxSize,                        maxWidth: boxSize,                        minHeight: boxSize,                        maxHeight: boxSize)                 .padding(5)                          // this has each RowView set its own height correctly //            Text(title) //                .multilineTextAlignment(.leading) //                .padding(5)             // this forces both RowViews to have the same height, even though they are separate from each other             ZStack {                 Rectangle()                     .foregroundColor(.gray)                                  Text(title)                     .multilineTextAlignment(.leading)                     .padding(5)             }             .padding(5)             // this also forces both RowViews to have the same height //            Rectangle() //                .foregroundColor(.gray) //                .overlay(Text(title).padding()) //                .padding(5)         }     } } It seems strange that both independent RowViews will end up having the same height. Read the release notes and didn't see mention of this being a possible bug. Copy pasta and see the results if you'd like. Notice the Gray ZStack containers are all almost the same height? Make the test of the first row even longer. Notice how the second one increases it's height? Is this a bug,? Are ZStacks never supposed to be nested?

Hi! I've installed iOS beta 4 on my iPhone 11 Pro and since then, I lost the signal and I don't have data. I have another iPhone X with iOS 14, and I don't have issue with it. It only occurs on iPhone 11. I tried many things like: Reset network setting Turn off/on airplane mode Turn off/on cellular data Hard reboot Soft reboot Reset content and data Turn off/on roaming ... Same issues It seems that the cell is looking for the signal constantly. Do you have any idea how to fix it ?

I'm interested in exploring the idea of connecting an iPhone to a Mac/PC. The initial idea is to allow a computer to access/use the iPhones camera and microphone, but I guess I would also be interested in knowing more about how the communication between an iPhone and Mac/PC could work in a general sense too. There are many posts talking about an iPhone integrating with external hardware devices and MFI is mentioned as well as Redpark cables - but I'm not sure if these same things apply when working with a Mac/PC. So, some questions: What protocols, technologies or frameworks would I use send audio and video from an iPhone and a Mac using a USB cable (if the type of cable matters or makes a difference (ie USB-C vs USB-A), please call it out - but I think it's very likely the type of cable wouldn't make any difference) What protocols, technologies or frameworks would I use to send commands from a Mac to the iPhone using USB so that it can be handled by the iOS app It appears that developers are not able to send raw USB protocol/messages/packets unless the developer is a part of MFI, is that correct? Is there another way to achieve this communication? E.g. with some type of "middle-man" (ie a Redpark cable? some other device?) I've seen iOS applications that turn your phone into a webcam (they usually offer connectivity over USB and over the network (NDI)) - these applications require additional downloads on the Mac/PC. My assumption is that the iOS application is sending messages/packets to the Mac/PC application, and the Mac/PC application is then handling all the work to expose that video/auidio stream as a "camera" device to the system. Would this be the only way to achieve this functionality? Could you expose an iOS application as a camera to a Mac (ignoring PC for now) in a native way, so that it would work the same way it does when you plug in a webcam? Is this possible with MFI alone, or is this possible with a third party device (cable/hardware) in between the iPhone and Mac?

I have noticed that in iOS 14 the UIPickerView has by default a light grey background on the selected Row like shown here. https://developer.apple.com/design/human-interface-guidelines/ios/controls/pickers/ I noticed also that pickerView.showsSelectionIndicator is deprecated on iOS 14. Is there a way to change the background color to white and add separators to achieve a pre iOS 14 UIPickerView style? Thank you

Sometime, when I open the Widget Gallery, function getSnapshot(for:in:completion:) in TimelineProvider is not called. Is this a feature or a bug? When is this function called? Thank you.

I've a custom UIView to render a large piece of text using CATiledLayers. My draw(rect:) implementation is quite simple: override func draw(_ rect: CGRect) { 	let range = layoutManager.glyphRange(forBoundingRect: rect, in: textContainer) 	layoutManager.drawBackground(forGlyphRange: range, at: .zero) 	layoutManager.drawGlyphs(forGlyphRange: range, at: .zero) } This code works without any issue on iOS 13, but fails with a crash on iOS 14 simulator: Thread 9: EXC_BAD_ACCESS (code=1, address=0x28) #0 0x00007fff2396a3f5 in _NSLayoutTreeMoveToGlyphIndex () I can see that draw(rect:) is being called from different threads in both iOS 13 and 14. However the EXC_BAD_ACCESS has never happened so far in iOS 13. I wonder whether this is a behaviour change in iOS 14 or an issue. If this is a change in NSLayoutManager, then is it still possible to use CATiledLayer to render large amount of text in coordination with NSLayoutManager?

I am using Xcode Version 12.0 (12A7208) with… picker.preferredDatePickerStyle = .wheels I have tried: picker.setValue(UIColor.white, forKeyPath: "textColor") // crash and … picker.tintColor = UIColor.white // no change and … UILabel.appearance(whenContainedInInstancesOf: [UIDatePicker.self]).textColor = UIColor.white // no change

In the following environment: iOS 14 beta, Xcode Version 12.0 beta 6 (12A8189n) try to implement user Apple Login with Firebase. Works until password entering screen and then hangs up on simulator or finished with error on device. Sign In with Apple is enabled in App.

When I set : tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 60, right: 0) The large title not show(small title instead of) when app first run, and it's right when I change contentInset's top to zero. I setup large title by this code: navigationController?.navigationBar.prefersLargeTitles = true I run it on iOS 13 is good, only break on iOS 14.

I have developed an app in Flutter and deployed iOS version in TestFlight. App works fine sometimes but on load, app freezes and user need to close the app many times. It works 1 out of 5 times. When i connect my device directly to my mac and run the app, it works fine. This problem is only on iOS and only on the app I downloaded from Testflight. I don't see any issues in the logs as well. App freezes on launch and no action works on the app. If I close it and reopen again, it works sometimes. My backend is NodeJS service hosted on AWS. The REST endpoint is not https but http. Not sure if this is causing the issue or some internal flutter or iOS process which is causing app to freeze. Same app in Android works perfectly fine.

I understand that every application requires a unique name. I am wondering if the name under the icon (I think that is the display name) can be a duplicate?

I have a camera app. I want to test it in the simulator I can't succeed to do this. I read it was simply not possible. I cannot believe that Apple does not grant access to the camera of the Host Mac from its iOS simulator How this could even be possible? At the price we pay for such material.... does the simulator able to use an externally USB connected camera ?

Hi, i want to do show the "Are you sure you want to leave this page?" in iOS Safari. How can I do that? On desktop browsers, I use this snippet (ReactJS): window.addEventListener('beforeunload', onUnload) And the implementation: useUnload((e) => { 		e.preventDefault() // Required for Firefox 		e.returnValue = '' 		delete e.returnValue 	}) Thanks!

I'm trying to record my screen (canvas) on iPad safari with the new experiential media recorder support. I got the mediaRecorder object and it triggers the start event but the issue is whenever mediaRecored record blob it will not trigger the stop event. It is working fine of MAC Safari but on iPad Safari I'm getting this issue. Is there any ways to get the stop event so mediaRecorder fire ondataavailable method after stop on iPad Safari?

It is noted that configurationDisplayName and description for iOS 14 Home Widget is not changing based on localization values added. How Apple's native apps doing the localization for the same.
