I can read the scrollPosition correctly, but scrollTo() doesn't work. iOS 17, Xcode 15.2. Code like this below(can directly copy and paste): import SwiftUI struct PositionTest: View { @State private var weathers = Weather.samples @State private var scrollPosition: Weather.ID? @State private var isTaped: Bool = false var body: some View { VStack { Text("Scroll Position: " + (scrollPosition ?? "Cupertino")) if !isTaped { CollapsedView( weathers: $weathers, scrollPosition: $scrollPosition, isTaped: $isTaped ) } else { ExpandedView( weathers: $weathers, scrollPosition: $scrollPosition, isTaped: $isTaped ) } } .font(.title) .fontWeight(.semibold) .animation(.default, value: isTaped) } } #Preview { PositionTest() } struct CollapsedView: View { @Binding var weathers: [Weather] @Binding var scrollPosition: Weather.ID? @Binding var isTaped: Bool var body: some View { ScrollViewReader { proxy in ScrollView { VStack(spacing: 20) { ForEach(weathers) { weather in Text(weather.name) .frame(width: 350, height: 227) .foregroundStyle(.white) .background(.blue.gradient) .cornerRadius(40) .id(weather.id as Weather.ID?) .onTapGesture { isTaped.toggle() } } } .frame(maxWidth: .infinity) .scrollTargetLayout() } .scrollIndicators(.hidden) .scrollTargetBehavior(.viewAligned) .scrollPosition(id: $scrollPosition, anchor: .center) .onAppear { proxy.scrollTo(scrollPosition, anchor: .center) } } } } struct ExpandedView: View { @Binding var weathers: [Weather] @Binding var scrollPosition: Weather.ID? @Binding var isTaped: Bool var body: some View { ScrollViewReader { proxy in ScrollView { VStack(spacing: 20) { ForEach(weathers) { weather in Text(weather.name) .frame(width: 250, height: 227) .foregroundStyle(.white) .background(.indigo.gradient) .clipShape(.circle) .id(weather.id as Weather.ID?) .onTapGesture { isTaped.toggle() } } } .frame(maxWidth: .infinity) .scrollTargetLayout() } .scrollIndicators(.hidden) .scrollTargetBehavior(.viewAligned) .scrollPosition(id: $scrollPosition, anchor: .center) .onAppear { proxy.scrollTo(scrollPosition, anchor: .center) } } } } struct Weather: Identifiable { var id: String { name } let name: String let temp: Int static let samples = [ Weather(name: "Cupertino", temp: 12), Weather(name: "New York", temp: 13), Weather(name: "ShangHai", temp: 14), Weather(name: "London", temp: 15), Weather(name: "Las Vegas", temp: 16), ] } I found if I simply change the VStack to LazyVStack in both CollapsedView() and ExpandedView(), the scrollTo() method works fine. But in my project, for some reason I don't want to use LazyVStack, just want to use VStack, is there any way to make scorllTo() works in VStack?

While debugging my app on simulator for an extended time, Xcode tries to close the project after about 18 hours. This interrupts whatever process is happening in the app. Why does this occur and is it possible to keep the app running on the simulator?

I built an app using react native which runs fine on simulators and dev environments; however, it crashes at runtime when I run it with release configurations. It crashes both on simulators and physical devices. Any help understanding the crash log would be greatly appreciated.

I have an iOS app using Flutter that runs fine on iOS 17 but crashes on iOS 16 with the following error. I did not have this issue with older version of Xcode. I have attached the crashlog. This is what I see in the Xcode debug window. dyld[557]: Symbol not found: _$s7Network11NWInterfaceV13InterfaceTypeO13wiredEthernetyA2EmFWC Referenced from: <0E8CEF1B-6257-3DBF-9E33-E80DDE7EAA93> /private/var/containers/Bundle/Application/71D50E27-D60B-474F-B4D1-CB8ACFFD556C/Runner.app/Runner Expected in: <F9D5A7E3-1EFB-3879-B33F-FD16AB5E4AD5> /System/Library/Frameworks/Network.framework/Network My Xcode version is Version Version 15.2 (15C500b)

My Swift app iterates over two Array&lt;String&gt; and compares their elements. Something very strange is going on. I have the impression the compiler is doing some optimizations that I cannot understand: commenting out the print statement in MyInterface.run() improves the runtime from about 10 seconds to below 0.5 seconds, and that print statement is executed only once at the end of the program. Even commenting out the if above it has the same effect. I'm running the app in Xcode Instruments. When debugging it in Xcode, there is no difference when commenting out any of those two lines. Instruments shows that most of the time is spent in protocol witness for Collection.subscript.read in conformance [A], Array.subscript.read and similar, which in turn call different malloc, initialize, free and release methods. What's the problem with this code? import Cocoa @main class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ aNotification: Notification) { let x = Array(repeating: "adsf", count: 100000) let y = Array(repeating: "adsf", count: 100000) let diff = MyInterface(x: x, y: y) diff.run() } } class MyInterface&lt;List: RandomAccessCollection &amp; MutableCollection&gt; where List.Element: Comparable, List.Index == Int { private let algorithm: Algorithm&lt;List&gt; init(x: List, y: List) { algorithm = AlgorithmSubclass(x: x, y: y) } func run() { algorithm.run() if (0..&lt;1).randomElement() == 0 { print(algorithm.x.count) // commenting out this line, or the if above, makes the program 20x faster } } } class Algorithm&lt;List: RandomAccessCollection&gt; where List.Element: Equatable, List.Index == Int { var x: List var y: List init(x: List, y: List) { self.x = x self.y = y } func run() { } } class AlgorithmSubclass&lt;List: RandomAccessCollection&gt;: Algorithm&lt;List&gt; where List.Element: Equatable, List.Index == Int { override func run() { var count = 0 for _ in 0..&lt;1000 { for i in 0..&lt;min(x.endIndex, y.endIndex) { if x[i] == y[i] { count += 1 } } } let alert = NSAlert() alert.messageText = "\(count)" alert.runModal() } }

Topic : Attaching debugger via lldb to remote process on tv device Current status I launch an app on a remote tv device that is paired to a macbook using the command xcrun devicectl device process launch --start-stopped -d XXXX-XXXXXX, com.metasample.SampleApp -j launch.json App is launched in stopped state and waiting for debugger to be attached to continue execution Using the XCode->Debug->Attach to Process, I am able to select the process and connect to the process and execute the app through the debugger. Expectation I would want to replace step 3 and use a command line instead to attach the debugger to the remote process instead of doing it via XCode.(the reason is to automate the execution without any manual intervention) I know the process id of the app on the remote tv device when i inspect the launch.json file that is created when the launch the app. eg pid 312 I also know the ip address of the device eg ip 192.168.178.29 However I do not know how to establish the debug session using lldb from command line. I launch lldb in the command line and execute these commands platform select remote-tvos target create /Users/works/apps/SampleApp-Payload/SampleApp.app/SampleApp gdb-remote 192.168.178.29: "what is the port?" - I do not know what port to connect to? Many Thanks for your suggestions and inputs on how to connect to the remote app via command line lldb.

Hi all, Since iOs 17.2 all the with the attribute role="text" and attr.aria-label="anytext" are not read by voiceover anymore. Example code: Could you please help me understand how to solve this issue?

When a user updates their device to iOS 17 (any version) on a device with MDM, our app crashes but only on some device, not all. The same app runs fine on iOS 16. We cannot recreate the issue in-house and even our customers cannot reliably recreate the crash as it only happens on some devices and not others. The crash we get is: SIGABRT: UICollectionView internal inconsistency: missing final attributes for cell Once the device gets this crash, the only way to fix it is to delete and reinstall the app and then everything works fine. Anyone having a similar issue with iOS 17 and MDM?

Hi, I don't know if it's okay to mention the app name? We developed an app in the Philippines and we can search and download our app here. However, when we requested our friends to download and test our app in the US, they are unable to search for the app. Our friends currently live in New York, Los Angeles, and New Mexico. The app's availability status is 'Available' for 174 countries (which includes United States). Any ideas on what causes this issue?

When I embedded a PhotosPickerView() in popover, it won't works: struct PhotoPickerTest: View { @State private var selectedPhotoItem: PhotosPickerItem? @State var isTaped: Bool = false var body: some View { Button("", systemImage: "plus") { isTaped = true } .popover(isPresented: $isTaped) { PhotoPickerView() } } func PhotoPickerView() -&gt; some View { PhotosPicker(selection: $selectedPhotoItem) { Image(systemName: "photo") } } } but if I just replace "popover" to "sheet", it works fine: struct PhotoPickerTest: View { @State private var selectedPhotoItem: PhotosPickerItem? @State var isTaped: Bool = false var body: some View { Button("", systemImage: "plus") { isTaped = true } .sheet(isPresented: $isTaped) { PhotoPickerView() } } func PhotoPickerView() -&gt; some View { PhotosPicker(selection: $selectedPhotoItem) { Image(systemName: "photo") } } } I think it's a bug, and bothered me a lot, hope apple engineers can fix it.

I developed an application using React Native and the help of expo. The app is fully functioning using Expo Go, however, when I upload a build and test it through TestFlight the app instantly crashes when opened and I am struggling to be able to read through the crash report. Below is the crash report, any help or direction would be greatly appreciated. Crash Report

sample.ips.txt Xcode, MacSymbolicator and QuickLook all fail to consider the symbols from the lastExceptionBacktrace of a modern .ips crash report. I have attached a full report as an example (I had to change its extension to txt or I wouldn't be able to upload it - change it back to ips and then use Quicklook to see its contents, which will be missing the backtrace). Here's the excerpt that matters: "lastExceptionBacktrace": [ { "imageOffset": 992564, "symbol": "__exceptionPreprocess", "symbolLocation": 164, "imageIndex": 13 }, { "imageOffset": 106164, "symbol": "objc_exception_throw", "symbolLocation": 60, "imageIndex": 25 }, { "imageOffset": 274836, "symbol": "-[__NSDictionaryM setObject:forKeyedSubscript:]", "symbolLocation": 1176, "imageIndex": 13 }, This trace is missing from a symbolicated report - I only get to see the main threads. Here's the start of that report: ------------------------------------- Translated Report (Full Report Below) ------------------------------------- Process: Find Any File [2616] Path: /Applications/Find Any File.app/Contents/MacOS/Find Any File Identifier: org.tempel.findanyfile Version: 2.4.1 (355) Code Type: ARM-64 (Native) Parent Process: launchd [1] User ID: 0 Date/Time: 2024-01-09 11:31:33.8066 -0600 OS Version: macOS 14.3 (23D5043d) Report Version: 12 Anonymous UUID: E3DD5ECE-F28C-31BA-A2EA-DE39D4284163 Time Awake Since Boot: 990 seconds System Integrity Protection: enabled Crashed Thread: 11 Dispatch queue: Folder size calc (Macintosh HD) (QOS: UNSPECIFIED) Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 6 Abort trap: 6 Terminating Process: Find Any File [2616] Application Specific Information: abort() called Thread 0:: Dispatch queue: com.apple.main-thread 0 CoreAutoLayout 0x18cecbdd8 -[NSISEngine hasValue:forEngineVar:] + 284 1 AppKit 0x187f51894 NSViewActuallyUpdateFrameFromLayoutEngine + 128 2 AppKit 0x187f11790 -[NSView layout] + 636 Contrary to this, when I get a similar crash report from an older macOS version where it still uses the older .crash instead of .ips files, I get to see the backtrace and can symbolicate it as expected. This seems to be a major bug in the symbolicator for ips files, and it's been around for years. I'm surprised that this is still not taken care of. Am I the only one who's noticing this?

Hi all! My new iOS app (first one in Swift and SpriteKit, was using ObjectiveC and Cocos2D before, a few years back) - got rejected with the dreaded "We were unable to review your app as it crashed on launch.", That's especially bad news when it never ever crashed on any on our devices when testing (variety of phones, iPads and all sort of iOS) either in debug or release, before submission. So no luck repro-ing! The crashlog text file apple review team sent back, renamed as .crash, seems to open in Xcode (right click on it) when linked to the right project and seems to point in the leaderboard code fetching the local authenticated user's score. This is some code that I shamelessly copy/pasted from a StackOverflow page a few months ago, and seemed to work right away so moved-on back then, but something must be unsafe in there (sorry, bit of a rookie with Swift optionals etc). Any help would be much appreciated as this code seems to work fine in debug, without warnings or anything, and also works fine in release using TestFlight - so we simply cannot repro the apple QA issue, and we need to fix it blind! This is the function below that is crashing, right on the line that has the "{ player, _, _ in ": func sync_hiscore() { if (GKLocalPlayer.local.isAuthenticated) { if #available(iOS 14.0, *) { GKLeaderboard.loadLeaderboards( IDs: ["HatStacker_LD01"] ) { leaderboards, _ in leaderboards?[0].loadEntries( for: [GKLocalPlayer.local], timeScope: .allTime ) { player, _, _ in // &lt;&lt;&lt;&lt; !!! CRASHES HERE!! if ( player!.score &gt; player_hiscore) { player_hiscore = player!.score } } } } } } I've also attached the full crashlog if that's of any help! Many thanks all, sorry for such a Swift rookie question, but to add to the confusion this is also the first time one of our apps gets rejected for such an obvious bad crash at launch, that no one has seen during our weeks of testing! Any idea why it's only in release and only in the apple HQ/review env that we get that error? Could they have an invalid Game Center account that is confusing the "player" score fetching? Cheers, JBB HatStacker_build4.crash

XCode 15 can't run on iOS 17 devices. Simulator 17.2 is installed. Working perfectly in simulator iOS 16 devices and below works. Devices: Sonoma 14.2 (M1 Pro 16") XCode 15.1 iOS 17.1( iPhone 15 Pro) I've tried many things and nothing works: Restarting XCode Restarting Mac Restarting devices Turning on Developer Mode Re-trust Mac devices multiple times Turning off VPN. I don't even use VPN (https://developer.apple.com/forums/thread/737875) Tried XCode 15.2 beta too. Same issue. Using multiple USB-C cable. Including thunderbolt cable. Force every device to connect to 5GHz network and 2.4GHz network. Turning off WiFi, Bluetooth, Mobile Data on Mac + iOS device. Re-trust the device. this one is a real head scratcher because network is not related to the issue... The issue I experienced: Always the same error: Previous preparation error: An error occurred while communicating with a remote process.. The connection was invalidated. Capacity in Device and Simulator window in XCode is unknown (should've been 64GB, 128GB, etc) Surely I'm not the only one experiencing this? Super annoying and I have lost 9++ hours debugging this without any avail. Error when connected via cable.

Hello. I'm seeing an inconsistent behavior where breakpoints I set in my (Swift) iOS app behave normally when I'm debugging on a device or on a simulator running iOS 17.x, but when I try using simulators of iOS 16 or 15 the breakpoints get ignored completely. I also observe that the breakpoints remain solid blue and do NOT adopt the dotted blue outline, as experienced by other users. I've seen a few posts on here and on SO about the general issue of ignored breakpoints (with no conclusive answer AFAIK), but I haven't seen any where the behavior varies with the SDK being used. The behavior is repeatable and predictable (within the same app at least). I am not adding the breakpoints after building/running, and I'm sure the logic reaches the lines with the breakpoints (and again, whenever I switch to an iOS 17 simulator, execution does pause as expected with the exact same breakpoints). Things I've tried and looked into: Clean up project build folder Delete and re-install simulators (iOS 16.4 and 15.5) Deleted the entire derived data directory, as well as the CoreSimulator one. Confirm the build configuration is Debug, and the "Debug executable" option is checked. inspect various build flags mentioned in other posts: {Swift compiler - Code generation - Optimization level - Debug: -0none; Debug information format: DWARF (I also tried DWARF with dSYM with no impact)}. Most of my settings are on the plain vanilla/out of the box side, with only a couple of SPM dependencies, and I've been maintaining the same app for about 5 years and don't think I've come across this behavior before. Currently using Xcode 15.1. Deployment target is 14.0. Thank you.

So I currently have a Firebase Firestore. That isn't necessarily what I need help with. The Firestore is set up correctly. The issue I am having is, I keep getting an error saying "Thread 1: "Failed to get FirebaseApp instance. Please call FirebaseApp.configure() before using Firestore"". Even though I am calling FirebaseApp.configure() before using Firestore. In fact, it's the first thing my app does when it runs. Anyone have any solutions? Here is the code in my @main file: import UserNotifications import FirebaseCore import FirebaseFirestore import SwiftUI class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool { // Firebase configuration // FirebaseApp.configure() // Notification setup UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert]) { granted, _ in guard granted else { return } DispatchQueue.main.async { application.registerForRemoteNotifications() } } return true } } @main struct MyApp: App { init() { FirebaseApp.configure() } @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate @Environment(\.colorScheme) var colorScheme let myData = MyData() var body: some Scene { WindowGroup { ContentView() .environmentObject(myData) .background(colorScheme == .dark ? Color.black : Color.white) .foregroundColor(colorScheme == .dark ? Color.white : Color.black) //.background(Color(red: 0.956, green: 1, blue: 1)) } } } And here is my code in the ContentView file (this is where I am getting the error): import FirebaseFirestore import FirebaseCore class MyData : ObservableObject { @Published var selectedTab : Int = 1 @Published var selectedView : ContentView.Views = .selectView @Published var selectedLawyer : ContentView.Lawyers = .selectLawyer @Published var selectedAgent : ContentView.Agents = .selectAgent @Published var selectedState : FiltersView.States = .selectState @Published var selectedStatus : ProfileView.Status = .looking @Published var isShowingProfile = false @Published var isShowingFilters = false @Published var isShowingSettings = false @Published var allowLoanOfficers = false @Published var allowFinancialAdvisors = false @Published var allowDivorceLawyers = false @Published var allowCriminalLawyers = false @Published var allowPersonalInjuryLawyers = false @Published var allowCivilLawyers = false @Published var allowCorporateLawyers = false @Published var allowTaxLawyers = false @Published var allowBusinessLawyers = false @Published var allowFinancialLawyers = false @Published var allowInsuranceLawyers = false @Published var allowEstateLawyers = false @Published var allowMedicalMalpracticeLawyers = false @Published var allowContractLawyers = false @Published var allowRealEstateLawyers = false @Published var allowRealEstateAgents = false @Published var allowIndividualSellers = false @Published var allowHealthInsuranceAgents = false @Published var allowAutoInsuranceAgents = false @Published var allowCommercialBrokers = false @Published var allowMortgageLenders = false @Published var allowMechanics = false @Published var name = "Please Add Name" @Published var filterCity = "" @Published var filterZip = 0 var filterZipString: String { // Computed property to get and set as String get { "\(filterZip)" } set { // Ensuring only numbers are accepted and updating the Int value if let number = Int(newValue.filter { "0123456789".contains($0) }) { filterZip = number } } } @Published var myLoanOfficers = 1 @Published var myFinancialAdvisors = 1 @Published var myDivorceLawyers = 1 @Published var myCriminalLawyers = 2 @Published var myPersonalInjuryLawyers = 1 @Published var myCivilLawyers = 1 @Published var myCorporateLawyers = 5 @Published var myTaxLawyers = 1 @Published var myBusinessLawyers = 2 @Published var myFinancialLawyers = 1 @Published var myInsuranceLawyers = 1 @Published var myEstateLawyers = 1 @Published var myMedicalMalpracticeLawyers = 1 @Published var myContractLawyers = 1 @Published var myRealEstateLawyers = 1 @Published var myRealEstateAgents = 2 @Published var myHealthInsuranceAgents = 1 @Published var myAutoInsuranceAgents = 1 @Published var myMechanics = 1 @Published var firstMyAgentTabOpen = true @Published var allowAutoCollapse = false @Published var isShowingLoanOfficers = false @Published var isShowingFinancialAdvisors = false @Published var isShowingDivorceLawyers = false @Published var isShowingCriminalLawyers = false @Published var isShowingPersonalInjuryLawyers = false @Published var isShowingCivilLawyers = false @Published var isShowingCorporateLawyers = false @Published var isShowingTaxLawyers = false @Published var isShowingBusinessLawyers = false @Published var isShowingFinancialLawyers = false @Published var isShowingInsuranceLawyers = false @Published var isShowingEstateLawyers = false @Published var isShowingMedicalMalpracticeLawyers = false @Published var isShowingContractLawyers = false @Published var isShowingRealEstateLawyers = false @Published var isShowingRealEstateAgents = false @Published var isShowingHealthInsuranceAgents = false @Published var isShowingAutoInsuranceAgents = false @Published var isShowingMechanics = false @Published var search = "" @Published var myAgentView = false @Published var messageSearch = "" @Published var selectedColor = Color.purple @Published var isShowingPurchases = false @Published var isShowingMonthlyPrices = true @Published var planType = "Plus" @Published var basicPrice = 29.99 @Published var plusPrice = 39.99 @Published var premiumPrice = 49.99 @Published var boostAmount = 1 @Published var oneBoost = 9.99 @Published var fiveBoosts = 37.49 @Published var tenBoosts = 49.99 private lazy var db = Firestore.firestore() init() { fetchInitialData() } private func fetchInitialData() { } } Anyone know any solutions? I have tried everything I can think of to get it to work.

When I try to use debug mode in Xcode, the app launches when initially started through the run command in Xcode. However, if I try to relaunch the app, it constantly fails (showing 1 second or so my splash screen before terminating). These are happening on real devices, provisioned via AppConnect. When I try to use the app and run it in release mode, relaunching sometimes works and sometimes it does not. Note that I am using Flutter and in the simulators, it works all great. These are the errors I get: domain: BSServiceConnectionErrorDomain; code: 3 ("OperationFailed"); "XPC error received on message reply handler"&gt;. Jan 2 01:14:09 SpringBoard(FrontBoard)[33] &lt;Error&gt;: [app&lt;com.example.myappnamehere(6DC11EF2-C3B9-459A-9210-004DA66051D2)&gt;:2287] Termination failed with error: Error Domain=RBSRequestErrorDomain Code=3 "No such process found" UserInfo={NSLocalizedFailureReason=No such process found} NSUnderlyingError = &lt;NSError: 0x2801a5e30; domain: BSServiceConnectionErrorDomain; code: 3 ("OperationFailed"); "XPC error received on message reply handler"&gt;; Jan 2 01:14:10 ReportCrash(MetricKitSource)[134] &lt;Error&gt;: Failed to create bundle record for bundleID &lt;private&gt; and error &lt;private&gt; Jan 2 01:15:56 SpringBoard(FrontBoard)[33] &lt;Notice&gt;: [(FBSceneManager):sceneID:com.example.myappnamehere-default][1] Scene invalidated with error: &lt;NSError: 0x2801a2d30; domain: BSServiceConnectionErrorDomain; code: 3 ("OperationFailed"); "XPC error received on message reply handler"&gt;. I noticed that sometimes I get these errors on a successful launch as well, except for this one: ReportCrash(MetricKitSource)[131] : Failed to create bundle record for bundleID and error This error is always shown when I fail to relaunch my app. Note that I do not see any other error logs. As the situation only happens when I first manually close my app (otherwise you can't relaunch, of course), the debugger log of Xcode etc. are not showing me anything anymore. Anyone knows what is happening here and how I can solve it?
