Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts

I have a Safari extension which allows the user to load their own homepage upon opening a new tab. The extension works by retrieving the homepage URL from UserDefaults and then redirecting to it using window.location.replace. In iOS 18, if the homepage is unable to be loaded due to, for example the user having no internet connection, Safari will go into an rapid loading loop, which eventually stops after a while. This is unlike iOS 17, where trying to reproduce the same scenario will end up with a Safari error page, which should be the expected behaviour. In short, instead of Safari going into an infinite loading loop, it should display a Safari error page like iOS 17 does. As this issue is only happening on iOS 18, I am almost certain it's an iOS bug and would appreciate if this can be fixed as soon as possible. I have created a Feedback Assistant report with ID FB15853821, which contains a sysdiagnose file from my iPhone 16 Pro, as well as two videos, one from my iPhone 16 Pro with iOS 18.2 beta 3 and the other video showing a comparison between iOS 18 and 17. Both videos first show the extension functioning correctly with an active internet connection, but when I disable my internet, the iOS 18 Safari goes into an infinite loop. Here are the steps to reproduce the issue: Download the Homepage for Safari app from the App Store: https://apps.apple.com/gb/app/homepage-for-safari/id6481118559 Enter any valid homepage URL, such as https://apple.com and tap Save Go to Settings -> Apps -> Safari -> Extensions -> Homepage and enable the extension Make sure Open New Tabs is set to “Homepage” Turn off both WiFi and cellular data and attempt to open a new tab in Safari Please note that this also happens with iOS 18.2 beta 4.

Hello, I would like to ask if there is any possibility to invoke the Apple Sysdiagnose via an API call. I cannot find any API reference for Sysdiagnose. I am aware only about the manually invocation. https://it-training.apple.com/tutorials/support/sup075/ However, this is pretty annoying since a reproduction of a hunted bug takes several hours, so I am looking for the way how to invoke Sysdiagnose from our code.

Hi Folks, starting with iOS18 and using Xcode16, accessing fetchedProperties results in an error. I identified the issue to occur as soon as the initialization of a fetched property with external binary data storage starts. Console output during debugging: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'This expression has evaluation disabled' *** First throw call stack: [...] libc++abi: terminating due to uncaught exception of type NSException Console output when trying to "print" the item via the contact menu of the debugger: Printing description of variable: error: error: Execution was interrupted, reason: internal ObjC exception breakpoint(-6).. The process has been returned to the state before expression evaluation. Message from debugger: killed The identical code works with iOS before iOS 18 (same for iPadOS 18). Does anyone observed a similar issue and figured out a solution already? Cheers, folox

We are experiencing problems with the USB port on iPad Pro 11 inch (M4) model number MVW13NF/A. Our custom peripheral device (based on Raspberry Pi Pico + tinyUSB stack, is configured as a network adapter class and has communication with our App over UDP protocol. Our device also acts as a DHCP server, providing the IP address for iPad. The problem can be described as a “bus stall” or "bus hold" after sleep mode. To reproduce it we just send the iPad into sleep mode using a power button, the USB bus on M4 goes to the suspended state and won’t resume anymore when we wake the iPad up. The problem has occurred since the upgrade to iOS 18.2.1 and has not been observed before on the previously installed iOS 17 on the same iPad Pro M4. Also, the problem does not happen on the iPad Pro 11 inch (3rd gen with M1) model number MHW73FD/A, with the same iOS 18.2.1 installed. The problem also does not arise, if we connect our device via USB hub to the same iPad Pro M4. We have tested different versions of tinyUSB stack (either included in RPi Pico SDK or native unpatched). The problem is independent of the library version. It occurs always if our device is connected directly to the USB port of iPad Pro (M4) with iOS 18. It also stays after upgrading to the latest iOS 18.3 (beta) In the attached logs is (reduced for clarity) debug output from tinyUSB library about events on the USB bus. These logs were captured via RTT debugging output, using Segger J-Link debugger, so logging process does not affect the timings on the USB bus. There are three logs attached, for cases 1: "iPad Pro M4 + iOS18" (i.e. problematic case), 2: "iPad Pro M1 + iOS18", and 3: "iPad Pro M4 + iOS18 + external USB hub" (they are non-problematic cases). case1_usbd_log.txt case2_usbd_log.txt case3_usbd_log.txt This was already posted as feedback with id FB16366509

Hi, We have recently encountered a problem running our App on iPads with A9, A10 chipset. Since recently we have migrated our Network module to swift 6 our app has stoped working on these devices. Anyone else has noticed that too or if someone know why that is happening only for iPads with specific hardware?

When trying to activate the VPN in the Settings menu of 18.4 beta (22E5200s) an error message pops up: ”The connection failed due to an irrecoverable error” The VPN works as expected with iOS and iPadOS 18.3.1 (22D72) and earlier releases.

This pertains to iPad apps and UITabbarController in UIKit. Our internal app for employees utilizes UITabbarController displayed at the bottom of the screen. Users prefer to maintain consistency with it being at the bottom. It becomes challenging to argue against this when users point out the iPhone version displaying it "correctly" at the bottom. My response is to trust Apple's design team to keep it at the top. One workaround is to develop the app using the previous Xcode version, version 15 (via Xcode Cloud), targeting padOS17. This ensures the tab bar is shown at the bottom of the screen. However, this approach has its drawbacks: Apple may not support it in the future, leading to missed secure updates for the app, among other issues. Exploring the UITabbarController mode appears to be the solution I am seeking. To quote the documentation "on iPad, If the tabs array contains one or more UITabGroup items, the system displays the content as either a tab bar or a sidebar, depending on the context. Otherwise, it only displays the content only as a tab bar.". The part "displays the content only as a tab bar." made think this is BAU: class ViewController: UITabBarController { override func viewDidLoad() { super.viewDidLoad() self.mode = .tabBar } } Unfortunately, this does not resolve the issue. Is there an API method that can force the tabbar to its previous bottom position? The app uses multiple windows. When we split a window to launch another instance, the tab bar appears at the bottom. This behavior seems tied to the form factor—or potentially to how many items are in the tab bar. We could build a custom tab bar to override this, but that goes against my “don’t reinvent the wheel” principle. Any comments we welcome and thank you for reading this (to the end) Theo

We are trying to write an iOS app that supports regular and constrained widths using a TabView with .tabViewStyle(.sidebarAdaptable). On the surface this seems like a great way to write an app that supports all the different widths that your app may run in. Especially since Stage Manager and Apple Vision have made it easy for users to resize your apps window while it is running. We are facing many challenges though. I will give a brief one liner of each below, but to truly experience them you need to run the sample app, or watch the sample videos included. Issues Basic TabView Issues Double Navigation Bar: When tabs are collapsed into a "More" tab, there's an unwanted double navigation bar Selection Sync: Tab selection gets out of sync when switching between narrow/wide layouts through the "More" tab TabView Crash Fatal crash occurs when resizing window to narrow width while Tab 5 is selected Error: SwiftUI/SidebarAdaptableTabViewStyle_iOS.swift:482: Fatal error: Tried to update with invalid selection value Section Handling Issues Section Display Bug: Bottom tabs incorrectly show section names instead of tab names in narrow width Tab Selection Mismatch: Tab identifiers don't match selected tabs in narrow width mode Customization Issues Inconsistent "Edit" button behavior in More tab Unable to properly disable tab customization Sample app and video https://github.com/copia-wealth-studios/swiftui-tabview-sample

Hello, Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices. Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations? TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.

Hello, why is apple won’t adding Just-In-Time compiler to ”Emulators” in the app store. And/or hypervisor for newer devices. i feel like UTM (which is a PC Emulator) or other Apps that emulate need JIT to work properly, and will consume significantly less battery to emulate/virtualize, And will have a noticeably better performance than just not enabling JIT, and by the way jit is already being used on iPadOS/iOS 18.3/18.3.1 and newer/older version of that so being enabled by the choice of the developer of the App is more convenient than doing it with tools. and by the why apple wont let emulators on iPads and newer iPhones do hypervisor, it’s better than JIT but requires a good cpu, like making it available to people with newer/powerful devices, hypervisor is better than JIT by a lot and removing it in iPadOS/iOS 18.4 was an unnecessary choice?, becuase it had a better potential in virtualization instead of emulating, and I feel like enabling it In M1-M2 iPads and A14-18pro and newer devices is just better from having it disabled, to unlock the fullest potential of the iPad it needs to have a app or something to do instead of just running high graphics games/or Apps.

input type="file"でアップロードした画像データからGPS情報が除去されます。 こちらはiPadOS16.5.1で発生しておりました。 iPadOS17.4.1、iPadOS18.3では正常にGPS情報が保持されます。 iOS、iPadOSのアップデートでGPS情報を保持するよう修正されたと見受けられますが、リリースノートを参照しても上記修正についての記事を見つけられませんでした。 お手数ですが、上記修正に該当する記事をご教示頂けませんでしょうか。 どうぞよろしくお願い致します。

I understand two key concepts from desktop platforms: Screen Mirroring – The same content is displayed on both the primary and external screens. Screen Extension – The external display shows different content that complements what's on the main screen. My question pertains to the second point: Is it possible to extend the display on iOS and iPadOS devices? I'm referring to this Apple documentation, which explains how to extend content from an iOS/iPadOS device to an external display. I tested this in a sample iOS Xcode project. In the iOS Simulator, I was able to detect an "external display" and present a separate UIWindow on it. However, when I tried the same on a real device (iPhone 15 connected to a MacBook Pro via cable), the external display connection was not detected. I’d like to confirm whether screen extension is possible on a real iOS device. From my research, it appears that extension is only supported on iPadOS via Stage Manager, but I want to verify if there’s any way to achieve this on an iPhone. If so, are there any known apps that currently utilize extended display functionality on iOS? If extension is not possible on iOS, what does the documentation mentions iOS?

I am using videojs player to play my hls m3u8 proxies, and there was no issue with ipad os 16, ater i upgraded it to 18, i started getting this warning -> [Warning] VIDEOJS: – "WARN:" "Problem encountered with playlist 0-https://coludFront.m3u8. Trying again since it is the only playlist." After this warning logs, the player just freeze's and even the source is not loaded into player. This issue doesn't exist in mac safari and iphone safari with latest os.

Hello, I've been using the @Environment(\.dismiss) var dismiss in a SwiftUI app for the last 2 years which means it was working as expected in iOS 16, iOS 17 and for the most part iOS 18 up until iOS 18.2.1 in which it is causing an endless loop and eventually a crash. It seems to be something about using a the @Environment(\.dismiss) with a NavigationLink which seems to cause this issue. When I add a log in my swiftUI views with let _ = Self._printChanges(), I see the following printed out in a loop: CurrentProjectView: _dismiss changed. SurveyView: @self changed. Similar issues have been reported: https://forums.developer.apple.com/forums/thread/720803 https://forums.developer.apple.com/forums/thread/739512 Any idea how to resolve this ?

I purchased an iPad Pro M4 in early December, and since day one, I’ve been experiencing a recurring issue. Almost every day, at random times, the device freezes for 1–5 minutes and then restarts itself. The tablet is not under heavy load when this happens — I mainly use it for light tasks such as watching videos in a player or Safari browser, web surfing, and reading books. The issue has even occurred while the iPad was idle and locked; it froze, displayed the Apple logo, and rebooted. I brought the device back to the store where I purchased it, and they sent it for a diagnostic check. However, the experts concluded that the device is fully functional, and no defects were found. After one of these crashes, I noticed that my Apple Pencil started lagging (see video file IMG_5688.MOV). However, after another reboot, the issue with the Apple Pencil resolved itself. I’ve documented the issue with several video recordings showing the freezing and rebooting behavior, as well as error logs generated after such incidents. Device Details: Model: iPad Pro M4 Usage: Light tasks only (video streaming, web browsing, reading) Environment: No overheating, no resource-heavy applications running What could be causing this issue, and how can I resolve it? Any help would be greatly appreciated. Thank you! P.S. I’ve uploaded all the device logs and videos demonstrating the issue to Google Drive. https://drive.google.com/drive/folders/1_R0i_iazADWo5EgStrPdgmf1XjgPP_RC?usp=sharing

With iPadOS 18, the UITabBar now defaults to the floating style. I successfully reverted the tab bar to its traditional style by overriding the UITabBarController's horizontalSizeClass property: self.tabBarController?.traitOverrides.horizontalSizeClass = .unspecified When I launch the app on my Mac using Apple Silicon, TWO tab bars appear: One appears at the bottom of the screen, like a traditional tab bar. The second tab bar is still embedded in the app toolbar in its floating style. Is this a bug? How do you ensure that overriding the horizontalSizeClass will remove/hide the floating tab bar when running an app on Apple Silicon? TIA! (Demonstrated on a test project)

I'm just trying to display an image that is stored in the local filesystem, but the more I dig into this the more confused I get. So previously I used this code (it's simplified): func findImage(name: String) -> UIImage? { do { let url = try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: false) .appendingPathComponent("MyFolder") .appendingPathComponent("\(name).png") guard let image = UIImage(contentsOfFile: url.path) else { return nil } return image } catch { print(error.localizedDescription) } return nil } Notice I create the URL with just .appendingPathComponent() and turning URL to path via url.path. It works! So what's the question? In Improving performance and stability when accessing the file system I've read that you better use the new appendingPathComponent(_:isDirectory:), that's good, will do. Also url.path is deprecated in iOS18. Should I use url.path(percentEncoded:) instead? What should be the value of percentEncoded when accessing the local filesystem? In this adjacent thread I've read: Don't use UIImage(contentsOfFile:) either, because it's a path-based API. There's no URL-based equivalent, which is an Apple clue that should be doing something else. Is this true? Then how should I store and load my images? Just FYI, I create images like this: private func generateThumbnail(name: String) { guard let drawingWidth = canvasGeo?.size.width, let drawingHeight = canvasGeo?.size.height else { return } let thumbnailRect = CGRect(x: 0, y: 0, width: drawingWidth, height: drawingHeight) Task { UITraitCollection(userInterfaceStyle: .light).performAsCurrent { let image = self.canvasView.drawing.image(from: thumbnailRect, scale: UIScreen.main.scale) guard let data = image.pngData() else { return } // -- HERE do { try FileManager.default.createDirectory(at: try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true) .appendingPathComponent("MyFolder"), withIntermediateDirectories: true, attributes: nil) let filename = "\(name).png" let url = try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true) .appendingPathComponent("MyFolder") .appendingPathComponent(filename) try data.write(to: url, options: .atomic) // -- and HERE } catch { print(error.localizedDescription) } } } } My usecase — just save the user's PencilKit Canvas as an image and display it back to him on a different View. I'm on SwiftUI and iOS 16+. Would be happy to learn the correct way, thanks!
