The app provides a simple drawing functionality on a canvas without using a storyboard. After creating drawings in portrait mode, rotating the simulator or the iPad-Device to landscape mode does not update or rescale the existing drawings to fit the newly expanded canvas area. The app can also be launched directly in landscape mode, allowing drawings to be created before rotating the device back to portrait mode. However, the issue persists, with the drawings not adjusting to the new canvas dimensions.
The goal is to achieve the same behavior as in the Apple Notes app: when the iPad is rotated, the drawings should adjust to the newly expanded or reduced canvas area. I would appreciate any suggestions or solutions.

I've developed an app in swift and UIKit. Its multi linguistic app supports English and Arabic. When I change the language from English to Arabic or Arabic to English. After changing language, when I navigate through different screens crash is happening randomly on different screens most of the time when I tap to navigate to a screen. And cash log is:
This time crashed with this error Exception NSException * "Not possible to remove variable:\t945: <unknown var (bug!) with engine as delegate:0x2824edf00>{id: 34210} colIndex:261 from engine <NSISEngine: 0x15c5dd5f0>{ delegate:0x15c594b50\nEngineVars:\n\t 0: objective{id: 31542} rowIndex:0\n\t 1: UIButton:0x15c6255b0.Width{id: 31545} rowIndex:1\n\t 2: 0x281c41450.marker{id: 31548} colIndex:1\n\t 3: UIButton:0x15c6255b0.Height{id: 31547} rowIndex:1073741824\n\t 4: 0x281c412c0.marker{id: 31546} colIndex:1073741825\n\t 5: UIButton:0x15c625a50.Width{id: 31549} rowIndex:11\n\t 6: 0x281c41270.marker{id: 31544} colIndex:2\n\t 7: UIButton:0x15c625a50.Height{id: 31551} rowIndex:1073741825\n\t 8: 0x281c414a0.marker{id: 31550} colIndex:1073741826\n\t 9: UILabel:0x15c625d10.Height{id: 31553} rowIndex:1073741826\n\t 10: 0x281c41590.marker{id: 31552} colIndex:1073741827\n\t 11: UIImageView:0x15c625870.Width{id: 31555} rowIndex:3\n\t 12: 0x281c41360.marker{id: 31554} colIndex:3\n\t 13: UIImageView:0x15c625870.Height{id: 31557} rowIndex:1073741827\n\t 14: 0x281c413b0.marker{id: 31556} colIndex:1073741828"... 0x0000000282fb11a0
For switching language I'm using this code snippet:
private func restartApp() {
guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
let delegate = windowScene.delegate as? SceneDelegate,
let window = delegate.window else {
return
}
// Create a new root view controller
let vc : AppLoadingVC = AppRouter.instantiateViewController(storyboard: .Splash)
let nc = UINavigationController(rootViewController: vc)
ApplicationManager.sharedInstance.isUserLoggedIn = false
DispatchQueue.main.async {
if UserDefaults.isRTL {
UIView.appearance().semanticContentAttribute = .forceRightToLeft
SideMenuController.preferences.basic.forceRightToLeft = true
Localize.setCurrentLanguage("ar")
} else {
UIView.appearance().semanticContentAttribute = .forceLeftToRight
SideMenuController.preferences.basic.forceRightToLeft = false
Localize.setCurrentLanguage("en")
}
window.rootViewController = nc
window.makeKeyAndVisible()
}
}
Please anybody help me I've been stuck here since lot of days. I tried multiple things but all in vain.
Description:
1. When initiating the print flow via UIPrintInteractionController, and no printer is initially connected, iOS displays all possible paper sizes in the paper selection UI. However, if a printer connects in the background after this view is shown, the list of paper sizes does not automatically refresh to reflect only the options supported by the connected printer.
2. If the user selects an incompatible paper size (one not supported by the printer that has just connected), the app crashes due to an invalid configuration.
Steps to Reproduce:
Launch the app and navigate to the print functionality.
Tap the Print button to invoke UIPrintInteractionController.
At this point, no printer is yet connected. iOS displays all available paper sizes.
While the paper selection UI is visible, the AirPrint-compatible printer connects in the background.
Without dismissing the controller, the user selects a paper size (e.g., one that is not supported by the printer).
The app crashes.
Expected Result: App should not crash
Once the printer becomes available (connected in the background), the paper size options should refresh automatically.
The list should be filtered to only include sizes that are compatible with the connected printer.
This prevents the user from selecting an invalid option, avoiding crashes.
Actual Result: App crashes
The paper size list remains unfiltered.
The user can still select unsupported paper sizes.
Selecting an incompatible option causes the app to crash, due to a mismatch between UI selection and printer capability.

I've been beating my head against the wall over a scrollview issue where the top and bottom are cut off in landscape mode. Portrait mode - everything runs swimmingly. The moment I flip the iPad on its side, though, I lose about a quarter of the view on the top and bottom. I thought this was something to do with framing or such; I ran through a myriad of frame, padding, spacer, geometry...I set it static, I set it to dynamically grow, I even created algorithms to try to figure out how to set things to the individual device.
Eventually, I separated the tablet and phone views as was suggested here and on the Apple dev forums. That's when I started playing around with the background image. Right now I have....
ZStack {
Image("background")
.resizable()
.scaledToFill()
.ignoresSafeArea()
ScrollView {
VStack(spacing: 24) {....
The problem is the "scaledToFill". In essence, whenever THAT is in the code, the vertical scrollview goes wonky in landscape mode. It, in essence, thinks that it has much more room at the top and the bottom because the background image has been extended at top and bottom to fill the wider screen of the iPad in landscape orientation.
Is there any way to get around this issue? The desired behavior is pretty straightforward - the background image fills the entire background, no white bars or such, and the view scrolls against it.

After implementing the method of obtaining video streams discussed at WWDC in the program, I found that the obtained video stream does not include digital models in the digital space or related videos such as the program UI.

We've noticed a pretty common crash that's occurring in our app that appears to only be affecting iOS 18 users. The code in question is below:
func getThing() async throws -> ThingData {
guard shouldRefresh, let data = self.thingData else {
let remoteThingData = try await store.getThingData()
self.thingData = remoteThingData
return remoteThingData // Crash happens here
}
return data
}
The crash happens on a background thread and the actual crash is:
Crashed: com.apple.root.user-initiated-qos.cooperative
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x00000004a67149c0
We haven't been able to reproduce the error ourselves but in the past 90 days all of the crashes (several thousand) have been only on iOS 18.
We also found this thread that appears similar from 2 years ago but unsure if it's related because in our case the guard can only be calculated at runtime so there shouldn't be any optimizations happening.
In app purchase is not executed in ios while i run the code in xcode 16.3
But it's working fine in Xcode 16.0.
There is no proper error message or any alerts showing. It just returns an empty product identifier.
Provide the me the solution or kindly fix the issue in xcode IDE regarding this issue in latest xcode
A functioning Multiplatform app, which includes use of Continuity Camera on an M1MacMini running Sequoia 15.5, works correctly capturing photos with AVCapturePhoto. However, that app (and a test app just for Continuity Camera) crashes at delegate callback when run on a 2017 MacBookPro under MacOS 13.7.5. The app was created with Xcode 16 (various releases) and using Swift 6 (but tried with 5). Compiling and running the test app with Xcode 15.2 on the 13.7.5 machine also crashes at delegate callback.
The iPhone 15 Continuity Camera gets detected and set up correctly, and preview video works correctly. It's when the CapturePhoto code is run that the crash occurs.
The relevant capture code is:
func capturePhoto() {
let captureSettings = AVCapturePhotoSettings()
captureSettings.flashMode = .auto
photoOutput.maxPhotoQualityPrioritization = .quality
photoOutput.capturePhoto(with: captureSettings, delegate: PhotoDelegate.shared)
print("**** CameraManager: capturePhoto")
}
and the delegate callbacks are:
class PhotoDelegate: NSObject, AVCapturePhotoCaptureDelegate {
nonisolated(unsafe) static let shared = PhotoDelegate()
// MARK: - Delegate callbacks
func photoOutput(
_ output: AVCapturePhotoOutput,
didFinishProcessingPhoto photo: AVCapturePhoto,
error: (any Error)?
) {
print("**** CameraManager: didFinishProcessingPhoto")
guard let pData = photo.fileDataRepresentation() else {
print("**** photoOutput is empty")
return
}
print("**** photoOutput data is \(pData.count) bytes")
}
func photoOutput(
_ output: AVCapturePhotoOutput,
willBeginCaptureFor resolvedSettings: AVCaptureResolvedPhotoSettings
) {
print("**** CameraManager: willBeginCaptureFor")
}
func photoOutput(_ output: AVCapturePhotoOutput, willCapturePhotoFor resolvedSettings: AVCaptureResolvedPhotoSettings) {
print("**** CameraManager: willCaptureCapturePhotoFor")
}
}
The crash report significant parts are.....

Of course, the MacBookPro is an old device - but Continuity Camera works with the installed Photo Booth app, so it's possible.
Any thoughts on solving this situation would be appreciated.

I'm trying to switch to UIKit's document lifecycle due to serious bugs with SwiftUI's version.
However I'm noticing the template project from Xcode isn't compatible with Swift 6 (I already migrated my app to Swift 6.). To reproduce:
File -> New -> Project
Select "Document App" under iOS
Set "Interface: UIKit"
In Build Settings, change Swift Language Version to Swift 6
Run app
Tap "Create Document"
Observe: crash in _dispatch_assert_queue_fail
Does anyone know of a work around other than downgrading to Swift 5?
We have successfully obtained the permissions for "Main Camera access" and "Passthrough in screen capture" from Apple. Currently, the video streams we have received are from the physical world and do not include the digital world. How can we obtain video streams from both the physical and digital worlds?
thank you!

Is there a swift6 manual that will teach me how to code in swift?
So…I am hitting a wall here and could use some guidance towards best practice.
I’ve developed an app in Xcode/SwiftUI that renders just fine on the iPhone - text, images, buttons, frames…everything is nicely centered on the screen or scrolls where and when I want.
The iPad though…not so much. I’m having issues with tops and bottoms being cut off in scrollviews. These are just straight up text screens too - the ones with other elements/controls…they’re rendering fine.
I’ve tried a mix of geometry, vstack, scrollview, padding, spacers…the lot of it. Nothing I seem to do works - the views do not want to fill and fit properly.
And, of course, the issue becomes worse the moment you flip the iPad into landscape view. Or use the 13” models.
I’d imagine others are battling these issues as well and found solutions, so I decided to hit up the brain trust.
I have an iOS app.
When I install pods via CLI to my project for the first time, launch Xcode, and then run the app, everything works fine – no build errors.
But after several instances of running the project on my device, all of a sudden build errors appear like:
/Pods/FirebaseCrashlytics/Crashlytics/Crashlytics/Settings/Models/FIRCLSApplicationIdentifierModel.m:19:9 'Crashlytics/Shared/FIRCLSByteUtility.h' file not found
/Pods/PostHog/vendor/libwebp/ph_sharpyuv_csp.h /Pods/PostHog/vendor/libwebp/ph_sharpyuv_csp.h: No such file or directory
And I have no idea why if it's because of my PodFile or any Build Settings/Phases/Rules, but this keeps happening repeatedly and it's impossible to develop anything with this.
I've tried a string of commands such as "pod deintegrate", "pod cache clean --all", removing PodFile.lock and doing pod install again, removing derived data, and cleaning build folder. I still keep running into the same build error and it's always after a few builds this happens, nothing is missing prior when the project successfully builds.
Here is my PodFile for reference:

I have an iOS app where I'm trying to paste something previously copied to the user's UIPasteboard. I came across the UIPasteControl as an option for a user to tap to silently paste without having the prompt "Allow Paste" pop up.
For some reason, despite having what seemingly is the correct configurations for the UIPasteControl, on testing a tap, nothing is called. I expected override func paste(itemProviders: [NSItemProvider]) to fire, but it does not.
Any help would be appreciated as there doesn't seem to be much info anywhere regarding UIPasteControl.
import UniformTypeIdentifiers
class ViewController: UIViewController {
private let pasteControl = UIPasteControl()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .systemBackground
pasteControl.target = self
pasteConfiguration = UIPasteConfiguration(acceptableTypeIdentifiers: [
UTType.text.identifier,
UTType.url.identifier,
UTType.plainText.identifier
])
view.addSubview(pasteControl)
pasteControl.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
pasteControl.centerXAnchor.constraint(equalTo: view.centerXAnchor),
pasteControl.centerYAnchor.constraint(equalTo: view.centerYAnchor),
])
}
}
extension ViewController {
override func paste(itemProviders: [NSItemProvider]) {
for provider in itemProviders {
if provider.hasItemConformingToTypeIdentifier(UTType.url.identifier) {
provider.loadObject(ofClass: URL.self) { [weak self] reading, _ in
guard let url = reading as? URL else { return }

Is there any possibility to update constraints for elements inside CollectionViewCell with button tap?

Hi Everyone,
I’m currently working on a flow where a web page redirects to our app to perform certain actions, and then returns the user back to the browser. However, on iOS, the only way to go back to the browser is by using the openURL method. The issue is that this method can only open the browser app itself—it can’t control which tab or page is shown, so the user doesn’t return to the original tab they came from. The same limitation also applies to Android.
Furthermore, iOS doesn’t allow an app to programmatically return to the previous app (in this case, the browser). While Android doesn’t have an official way either, in some cases, the OS automatically returns to the previous app when ours is closed.
I’d like to ask:
Is there any known method or workaround that allows returning from my app back to Safari (or the default browser) and restoring the previously active web page or tab?
Or, is there any way to programmatically return to the previous app from within my app?
Thanks in advance for your support!
Hi,
I have a couple of questions in regards to testing in-app purchases. I tested the subscription on a device but I'm not sure how to reset so I can test again. I didn't see the subscription in device settings or in Debug -> StoreKit -> Manage Subscriptions window. Additionally, I was wondering if there was a way to detect the subscription being made. I implemented this, but I'm not sure if that will work:
.onChange(of: Product.SubscriptionInfo.RenewalState.subscribed) {
if Product.SubscriptionInfo.RenewalState.subscribed == .subscribed {
}
}
I need your help, my pass is window 11, Lenovo laptop and I have 6gb and 512gb storage and I have to run export on us through virtual machine because I have pass membership to run display on I can use it in a window 11 laptop....
thank you 🙏🏻
Yours faithfully
