Problem Our app use UIPasteControl for people taps to place pasteboard contents in UITextView. It worked fine at first, but recently received a lot of user feedback and the button suddenly disappeared This problem usually occurs when an App switches between the front and back More Information When the button disappears, we find that the child view of the UIPasteControl control which name _UISlotView has a size of zero. we use UIKit and AutoLayout，limit button size (100, 36) let config = UIPasteControl.Configuration() config.displayMode = .labelOnly config.cornerStyle = .fixed config.baseForegroundColor = .white config.baseBackgroundColor = .black config.cornerRadius = 18 let btn = UIPasteControl(configuration: config) pasteBtn = btn addSubview(pasteBtn) pasteBtn.snp.makeConstraints { make in make.trailing.equalTo(-20) make.bottom.equalTo(-10) make.size.equalTo(CGSize(width: 100, height: 36)) } UI view information <UIPasteControl: 0x107dda810; frame = (0 0; 100 36); layer = <CALayer: 0x3010ff000>> (lldb) po [0x107dda810 subviews] <__NSSingleObjectArrayI 0x30152ff00>( <_UISlotView: 0x107dea630; frame = (0 0; 100 36); userInteractionEnabled = NO; layer = <CALayer: 0x3010eb460>> ) anyone meet before? is there a workaround?

iPhone 15pro iOS 18.2 Downloaded files cannot be located anywhere in Files, only by accessing Downloads in Safari. I have tried setting download folder to various locations, iCloud, Phone, Google Disk, but nothing is stored. Has an invisible cache or temp folder been introduced? If so, it is a total fail: When press-holding any file in Safari download, the normal file action options (Quick Look, share, store to Files, etc) are not available. When clicking any file it opens any of several apps that has this file type associated with it, and there is no way to change the default app or disable the forced opening of an app. I tried deleting the app opening .csv (in this case OneDrive), and another irrelevant app opened. There seems to be a hierarchy of apps-file types, and it has no logic to it. Tips?

Does iOS Automatically Reconnect to Disconnected BLE Devices, or Is It App-Driven? I have a few questions regarding BLE device reconnections in iOS: When a BLE device gets disconnected, does iOS automatically attempt to reconnect to it, or is it the app’s responsibility to handle the reconnection logic? If the app doesn’t initiate a BLE scan, will the OS still attempt to reconnect to previously paired devices, or is manual intervention by the app necessary? What is the recommended approach to re-establish a BLE connection when: The app has been deleted. The BLE device remains connected in the iPhone's Bluetooth settings. The app is reinstalled later. Any insights or best practices would be greatly appreciated!

I think I know the answer after speaking with ChatGPT but I figured I'd ask here in case someone found some hack. What I'm trying to do is play music through two bluetooth speakers using any streaming platform? I have tried connecting to two speakers through the OS and then tried setting up an AVAudioSession and messing with the options and Categories to achieve this but have been unsuccessful, and have even tried seeing if it could at least be done with playing music from the app I've created myself with a .mp3 file which also has been unsuccessful. I've read there possibly could be something with hardware/firmware that could be done to achieve this for iOS but I'm trying to see what could be done app side first. Samsung phones have the ability to dual-stream, so is there really no way to achieve the same on iOS?

I love to use my iPhone as a camera. it is what makes this phone the best, ever, period But, ever since iOS 18 update, slow-mo capture & playback is a painful experience. Ok, I get it, it is not an action camera but I was able to have an instant-slow-mo-playback on prior iOS versions. But ever since iOS 18, I have to wait at least 5-10 minutes to "play" slow-mo video and I noticed something else, even though I didn't modify any settings on the video, iOS 18 creates slow-mo video file in phone's storage and takes up a LOT of space and often making me clean all of my files to find what was wrong the device. I think, in my all honesty, apple must pull iOS 18 update and work on it a little bit more. Till then, I'll be using my DJI Action Camera for 240fps, at least it works, instantly.

Hi I think I found an issue with SwiftUI List on iOS 18.0 and 18.1 Using the ContentView from the code block below: if you try to drag and drop the globe image onto the blue rows, things work fine on both iOS 17 and 18 with either List or VStack. However if you first drag and drop the image onto the Files app and then drag the newly created PNG file back into our app, it won't work on iOS 18 with the blue row inside the List. Also there's no visual feedback when hovering that blue row (unlike the one inside the VStack). I've tried various view modifiers but no luck so far. Any help is appreciated. Thank you. FB15618535 struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .resizable() .scaledToFit() .frame(height: 100) .draggable(Image(systemName: "globe")) List { Color.gray .frame(height: 100) Color.blue .frame(height: 100) .dropDestination(for: Image.self) { _, _ in print("List dropped") return true } } VStack { Color.gray Color.blue .dropDestination(for: Image.self) { _, _ in print("VStack dropped") return true } } } .padding() } }

Hi Team, We are integrating SwiftUI's Charts BarMark, UI looks good but when we try setting up custom ADA it doesn't reflect/override the accessibility label/value we set manually. Is it iOS defect or is there any workaround? Thanks in advance. Sample: Chart(data) { BarMark( x: .value("Category", $0.department), y: .value("Profit", $0.profit) ) .foregroundStyle(by: .value("Product Category", $0.productCategory)) .accessibilityIdentifier("BarMark") .accessibilityLabel("Dep: \($0.department)") .accessibilityValue("Profile: \($0.profit) Category: \($0.productCategory)") }

I have an iOS App which looks great on iPhone, portrait only, which makes a lot of use of UITableViews. On iPad those tables look stretched out in Landscape. On MacOS with Apple Silicon the app can be resized to any size and the table views look very stretched. There are views in the App which users want to resize so limiting app size not an option. I've been modifying the app's table views to limit their width and centre them using constraints. This isn't easy, it's a lot of work as UITableViewController doesn't allow for constraining the table width. Or does it? So I've changed them to UIViewControllers with UITableView imbedded in the root UIView with constraints. Looks really nice. Now I've just run into the limitation that static tables, which I have a number of, aren't allowed to be embedded. So how can I limit the width of them? I really don't want to add a lot of dynamic code. Please tell me there's an simpler, more elegant method to what really makes a much more aesthetically pleasing UI on iOS App running on iPad and MacOS? TIA!

I can't seem to access preview for any of my views in any of my swift projects at all (using Mac to code and using iPhone 16 pro as preview and simulation, simulation can work), even after restarting Mac and Xcode itself. The preview section has a popup saying "Cannot preview in this file, unexpected error occured" (for every file), please tell me what is wrong and help me solve it to see the preview, thank you! details

We are experiencing thousands of crashes in our application when attempting to present the camera through a Web View. The app crashes during this process, and the crash logs point to WebCore::AVVideoCaptureSource::create WebCore::RealtimeMediaSourceCenter::getUserMediaDevices. This issue has only been observed in iOS 18.2 beta versions (beta 1 - 22C5109p, beta 2 - 22C5125e, beta 3 - 22C5131e). In iOS versions below 18.2, the functionality works and we haven't identified any correlation with specific device models. The problem seems to stem from a WebCore framework introduced in these beta releases 18.2. We kindly request a review and fix for this issue in upcoming beta releases to restore functionality. Let us know if there are any workarounds or adjustments we can implement in the interim. Thank you for your attention to this matter.

I made an account on this site for the sole reason to post this. I can not stand the IOS 18 photo app, to put it bluntly its sucks, it's made the app unusable. I was nice, I'd thought I'd give it a month or two but no, it still sucks. I wish I could uninstall IOS 18 solely cause of it. I hate the UI, its utterly unintuitive.

I'm currently using Xcode 16 Beta (16A5171c) and I'm getting a crash whenever I attempt to fetch using my ModelContext in my SwiftUI video using the environment I'm getting a crash specifically on iOS 18 simulators. I've opened up a feedback FB13831520 but it's worth noting that I can run the code I'll explain in detail below on iOS 17+ simulator and devices just fine. I'm getting the following crash: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'The specified URI is not a valid Core Data URI: x-coredata:///MyApp/XXXXX-XXXXX-XXXX-XXXX-XXXXXXXXXXXX' It's almost as if on iOS18 SwiftData is unable to find the file on the simulator to perform CRUD operations. All I'm doing in my project is simply fetching data using the modelContext. func contains(_ model: MyModel, in context: ModelContext) -> Bool { let objId = palette.persistentModelID let fetchDesc = FetchDescriptor<MyModel>(predicate: #Predicate { $0.persistentModelID == objId }) let itemCount = try? context.fetchCount(fetchDesc) return itemCount != 0 }

Prior to iOS 18.1, App-prefs:Wallpaper deeplinked to the wallpaper settings. On iOS 18.1, it now deeplinks to the settings app. Is there a new URL to deeplink to the Wallpaper settings? The following URLs have been tested and do not work on iOS 18.1: App-prefs:Wallpaper App-prefs:wallpaper App-prefs:root=wallpaper App-prefs:root=Wallpaper App-prefs:root=WALLPAPER App-prefs:root=General&path=Wallpaper prefs:root=Wallpaper

Hi Apple Engineers, I am encountering an issue where the memory usage reported by the Xcode memory report and the Xcode Instruments memory profiler are not aligned. Specifically: Xcode Memory Report: After implementing autoreleasepool, URLSession reading a zip file, and moving the task inside DispatchQueue.global().async, the memory usage goes down from 900MB to 450MB, indicating a potential memory leak. Xcode Instruments Memory Profiler: The memory usage goes down from 900MB to 100MB, suggesting that the memory has been properly released and there is no significant memory leak. Could you please help me understand the discrepancy between these two tools and provide guidance on the appropriate way to interpret the memory usage in my application? Which result I should rely on it? I would greatly appreciate your insights and expertise on this matter. Thank you in advance for your assistance.

We've created a test app to highlight the problem: https://www.dropbox.com/scl/fi/3hl63t772qeguc1bxr9xi/Test.zip?rlkey=pofk3ji2s93ucq3r1l8m39z0u&dl=0 As you can see we have enforced exclusive touch in the init method, a solution which worked until iOS 18 which now doesn't work anymore. How can we force exclusive touch on SwiftUI in iOS 18+?

Hello In the past, the documentation and specifically design guidelines were quite clear about the fact that having an exit button was not a good thing, and programmatically exiting the app was prohibited and ground to rejection by the review team. Looking though the documentation and guidelines nowadays, I cannot find any explicit mention of this. We have a client that want us to add such button on the main menu of an app, and we are looking to hard evidence that this is against standards. Has Apple stance on this changed ? Or have I missed it in the doc somewhere ?

My app is using SwiftData, but I deployed it to the app store with no VersionedSchema applied without thinking about migrating the model. Now I need to migrate the data and I need help from someone who has experience moving from non-versioned to versioned. Assuming I currently have a version1, version2 schema, it works fine for the initial install situation, but when I migrate to version1, version2 in an app that is listed on the app store, I run into problems. I don't have any logs to show for it. Thread 1: EXC_BAD_ACCESS (code=2, address=0x16a6578f0) If anyone has had the same experience as above, please respond, thanks! Let me know what kind of logs you need and I'll add them as a comment.

Hey, There's like this darkish line on my iPhone and iPad when I open the Photos app. This scared the ding dong out of me the first time I saw it but then I realized in was a software issue when it disappeared as I swiped up to close the app. It's really weird because it's extremely faint but I can't seem to catch it in screenshots. I know for a fact this is a software issue because it doesn't show up in any other apps. It also changes from horizontal to vertical depending on how I turn my iPhone. Can everyone please just check your own iPhone or iPad to make sure I'm not the only one? I'm on the 18.2 developer beta by the way. Thanks!

Hi, I'm trying to create a UICollectionView where the cell high is automatic. Cells contains a UILabel with all anchors to the contentView of the cell. It seems to work but I have a strange behavior with longer text, on reload data and on device rotation: Cells do not display the whole text or they change row, both randomly. To create my collection view I first create the collection view with a custom flow layout setting the automatic size on viewWillAppear: let collectionViewFlowLayout = CustomFlowLayout() collectionViewFlowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize collectionView = UICollectionView(frame: .zero, collectionViewLayout: collectionViewFlowLayout) and I have also overridden: override func willAnimateRotation(to toInterfaceOrientation: UIInterfaceOrientation, duration: TimeInterval) { collectionView.setNeedsLayout() self.collectionView.layoutIfNeeded() self.collectionView.collectionViewLayout.invalidateLayout() //self.collectionView.reloadData() } Then, I created the custom layout as follow: import UIKit final class CustomFlowLayout: UICollectionViewFlowLayout { override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? { let layoutAttributesObjects = super.layoutAttributesForElements(in: rect)?.map{ $0.copy() } as? [UICollectionViewLayoutAttributes] layoutAttributesObjects?.forEach({ layoutAttributes in if layoutAttributes.representedElementCategory == .cell { if let newFrame = layoutAttributesForItem(at: layoutAttributes.indexPath)?.frame { layoutAttributes.frame = newFrame } } }) return layoutAttributesObjects } override func layoutAttributesForItem(at indexPath: IndexPath) -> UICollectionViewLayoutAttributes? { guard let collectionView = collectionView else { fatalError() } guard let layoutAttributes = super.layoutAttributesForItem(at: indexPath)?.copy() as? UICollectionViewLayoutAttributes else { return nil } layoutAttributes.frame.origin.x = sectionInset.left if(indexPath.section == 0){ layoutAttributes.frame.size.width = collectionView.safeAreaLayoutGuide.layoutFrame.width - sectionInset.left - sectionInset.right } else if (indexPath.section == collectionView.numberOfSections - 1){ let width = ScreenUtility.getCollectionCellWidthForElement(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing, multiplier: 3) layoutAttributes.frame.origin.x = ScreenUtility.getCollectionCellOriginForElement(in: collectionView, at: indexPath, forElementHavingWidth: width, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing, multiplier: 3) layoutAttributes.frame.size.width = width } else if (indexPath.section == collectionView.numberOfSections - 3) || (indexPath.section == collectionView.numberOfSections - 4){ let width = ScreenUtility.getCollectionCellWidthForElement(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing) layoutAttributes.frame.origin.x = ScreenUtility.getCollectionCellOriginForElement(in: collectionView, at: indexPath, forElementHavingWidth: width, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing) layoutAttributes.frame.size.width = width } else { let width = ScreenUtility.getCollectionCellSizeForElementFullRow(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right) layoutAttributes.frame.origin.x = ScreenUtility.getCollectionCellOriginForElementFullRow(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right) layoutAttributes.frame.size.width = width } return layoutAttributes } } And finally on collection view cells: override func preferredLayoutAttributesFitting(_ layoutAttributes: UICollectionViewLayoutAttributes) -> UICollectionViewLayoutAttributes { setNeedsLayout() layoutIfNeeded() let targetSize = CGSize(width: layoutAttributes.frame.width, height: 0) layoutAttributes.frame.size = contentView.systemLayoutSizeFitting(targetSize, withHorizontalFittingPriority: .required, verticalFittingPriority: .fittingSizeLevel) return layoutAttributes } override func prepareForReuse() { self.nameLabel.text = "" self.idLabel.text = "" self.contentView.setNeedsLayout() self.contentView.layoutIfNeeded() } Let me show you an example on the iPad that is the worst. First Time I open the collection view I have cells on wrong rows and not sized properly Then I rotate the device portrait and the cells are fine On landscape again it changes behavior: This is just an example, things happens apparently randomly, and also sometimes cells disappear (I think the height is set to 0). I really do not understand why, cells width seems to be computed correctly, and cell label is set via setter: open var step: String = "" { didSet { nameLabel.text = step nameLabel.sizeToFit() self.contentView.setNeedsLayout() self.contentView.layoutIfNeeded() } }
