I have a swift project with a Watch companion. Since the update of Xcode in 16.3 version after updating MAcOs , Watch OS, iOS to the latest version . It is quasi impossible for me to make Xcode work with my series 10 Watch. I have a lot of alert box, messages in the "device & Simulator" tool like this Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. And many message telling me that Xcode is preparing the Watch , then that it has lost the connexion. I have to wait some minutes after EACH run of the App to test it again. This is very annoying . Some of the alerts I have : And the best to know , is that I can run the APP outside of Xcode , it works, Connects to the iPhone, fetch data and so. the iPhone sees the Watch without and problem. Reboots can solve for a few minutes the problem. But that is not a solution.

I am experiencing an issue where XCode reverts .xccurrentversion file in my iOS app to the first version whenever xcodebuild is run or whenever XCode is started. This means I can build the app and run tests in XCode if I discard the reversion .xccurrentversion on XCode start. However, testing on CI is impossible because the version the tests rely on are reverted whenever xcodebuild is run. The commands I run to reproduce the issue ❯ git status Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") ❯ git checkout "Path/.xccurrentversion" Updated 1 path from the index ❯ git status nothing to commit, working tree clean ❯ xcodebuild \ -scheme Scheme \ -configuration Configuration \ -sdk iphonesimulator \ -destination 'platform=iOS Simulator,name=iPhone 16 Pro,OS=latest' \ -skipPackagePluginValidation \ -skipMacroValidation \ test > /dev/null # test fails because model version is reverted ❯ git status HEAD detached at pull/249/merge Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") I have experienced such issue in 16.3 (16E140) and 16.2 (16C5032a). Similar issues/solutions I have found online are the following. But they are either not relevant or do not work in my case. https://stackoverflow.com/questions/17631587/xcode-modifies-current-coredata-model-version-at-every-launch https://github.com/CocoaPods/Xcodeproj/issues/81 Is anyone aware of any solution? Is there a recommended way I can run diagnostics on XCode and file a feedback?

Is anyone else receiving this warning from Xcode when running on the Simulator? "Failed retrieving MusicKit tokens: fetching the developer token is not supported in the simulator when running on this version of macOS; please upgrade your Mac to macOS Ventura." My Mac is already updated to macOS Sequoia, and I'm also running the latest version of Xcode. Feedback: FB17150538

macOS 15.4 I've just updated Xcode to version 16.3 via the the App Store. The project was previously working fine. After installing all components and Apple Intelligence, I loaded my SwiftUI-based iOS app project. Xcode Preview fails to load, with an error: "Failed to create simulator" == PREVIEW UPDATE ERROR: FailedToCreateDeviceError<SimRuntime>: Failed to create simulator Xcode Previews needs to create simulator devices for running previews Device Type: com.apple.CoreSimulator.SimDeviceType.iPhone-16-Pro Runtime: com.apple.CoreSimulator.SimRuntime.iOS-18-2 ================================== | NSError.com.apple.CoreSimulator.SimError.401: The iOS 18.2 simulator runtime is not available. | | Try reinstalling Xcode or the simulator runtime. | | com.apple.CoreSimulator.SimError (401): | ==NSLocalizedFailureReason: liblaunch_sim.dylib could not be opened I cleaned the build folder, tried again.

[SOLVED - restarted Mac again. Errors disappeared. Leaving this here for anyone else who has this issue.]

with the latest Xcode version, i am getting all kinds of errors: few main ones: /Users/akashbhatia/MyApp/ios/Pods/Target Support Files/ReactCodegen/ReactCodegen-prefix.pch:2:9 Could not build module 'UIKit' /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator18.4.sdk/System/Library/Frameworks/CFNetwork.framework/Headers/CFNetwork.h:18:10 Could not build module 'CoreFoundation' /Users/akashbhatia/MyApp/ios/Pods/Headers/Public/RCT-Folly/folly/portability/Config.h:20:10 'folly/folly-config.h' file not found I have reinstalled Xcode, removed derived data, installed pod over and over again, but I have realized from the first error here, that it has more to do with Xcode and React Native now. Any help will be appreciated.

I'm trying to load a Safari Extension onto my physical iPhone 15 running iOS 18.4 but am seeing the following message: "iOS 18.4 is not installed." When I click the Get button I see that the download has failed with the following error message. I tried updating my laptop to Sequoia and I also deleted and re-installed Xcode but that didn't fix it. Any thoughts? Download failed.

Xcode 16.2 runs well, but encountered the problem in Xcode 16.3.

Consider this stripped-down example of a view with a view model: import Observation import SwiftUI struct MainView: View { @State private var viewModel = ViewModel() private let items = [0, 1, 2] var body: some View { List { GroupedItemsView( viewModel : viewModel.groupState, groupedItems : [(0, items)] ) } } } fileprivate struct GroupedItemsView<ViewModel: GroupsExpandable>: View { let viewModel : ViewModel let groupedItems : [(ViewModel.GroupTag, [Int])] var body: some View { ForEach(groupedItems, id: \.0) { groupTag, items in Text("nothing") } } } fileprivate protocol GroupsExpandable: AnyObject { // HERE associatedtype GroupTag: Hashable } fileprivate final class GroupState<GroupTag: Hashable>: GroupsExpandable {} @Observable fileprivate final class ViewModel { var groupState = GroupState<Int>() } #Preview { MainView() } This compiles and runs fine in the Simulator, but it crashes in the Preview. However, when I remove the fileprivate modifier before GroupsExpandable (see HERE), it also runs in the Preview. What is the reason for this? Bug in Preview? Error on my side somewhere? Thanks. System is Xcode Version 16.3 (16E140) on a MacBook Pro 2018 (Intel) running Sequoia 15.3.2 Devices are iPhone 16 Pro Max with iOS 18.3.1, compiler is set to Swift 6.

I have an Watch APP and it's iOS APP .. I want to test it via the Simulator. (with my real Watch I have a lot of Xcode error and an open ticket with Apple) Xcode 16.2 associates an Iphone16 to the Series 10 Watch simulated. BUT the Watch is not associeted to the iPhone. WCSession.isSupported is true, but session.isPaired is false on the iPhone. On the Watch : session.isReachable returns false. But in its settings the Simulator shows the Watch. And It is the same problem with another model of Watch in the Simulator.

Xcode 16.3 build on ios18.4 ,app can't launch. Then lost connection to the debugger . but Xcode16.3 with ios18.3 can launch

I need to elicit the location of the user in the Siri intents and so I call: override init(){ super.init() self.locationManager=CLLocationManager() self.locationManager.delegate = self; self.locationManager.startUpdatingLocation() self.locationManager.requestWhenInUseAuthorization() } Still neither public func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) nor public func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) are ever called, notwithstanding the presence of the correct entry in the info.plist, the inclusion of the library and the indication of the delegation with: class IntentHandler: INExtension, INSendMessageIntentHandling, CLLocationManagerDelegate, UISceneDelegate are ever called. Is there any problem with CLLocation manager on intents? What would be a big problem as there is no way to share information with the main app!

I built an app in Python with Kivy and I'm trying to bring it over to iOS. I made an Xcode project out of it that builds successfully, but it fails to install in the simulator or onto a device.

I am using my real device and the Xcode Preview which works pretty fine. I do not want to show an empty canvas pane all the time. But when hiding the canvas, the preview pauses. I tried the refresh shortkey (OPT + CMD + P), too, while canvas is invisible. Why must the canvas be visible even there is no content besides "Previewing on iPhone from..." Info? I hope there is a workaround to hide the canvas while pushing to real devices.

Ever since updating to Xcode 16.3, auto-completing variable names in lldb does not work. Is this a known bug? Is there a workaround to get it do auto-complete again?

I'm working on a plugin, and that target works just fine. I made another target so I can test some computation functions. It doesn't need much from XcodeKit, just some of the structures. I added XcodeKit and Cocoa, but the import XcodeKit just says "no such module". If I switch to the plugin target, it's just fine. I've compared both schemes, but I don't see difference which would affect finding the framework.

It seems that Xcode gets confused when there is another format specifier before a plural variable. As shown in the screenshot, %#@VARIABLE@ %f works fine, but an error occurs with %f %#@VARIABLE@.

For an initial launch of Xcode, the GatherProvisioningInputs usually takes 60 seconds for a simple project. Subsequent build is fast though. But the build process seems got stuck at VeryModule of the MyFramework target, which usually takes 15 seconds.

We are building an iOS App and want to access or read SMS Text messages and Voicemails in order to back them up in a new service that we are building, Is that possible using Xcode? is there a special permission for that? Thank you in advance for the support
