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@.

Hi, i've been trying to install the latest simulator runtime from Apple and i can't seem to make it work.

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

I have my main app that connect to multiple internal modules. These modules are built with Xcode 15.4 on Jenkins. If I use these modules as xcframework in main app and try to build main app with Xcode 16.2 it will give error. Framework built with older version of Swift. I thought we have ABI stability with new Xcode versions. Any idea what can be issue?

Hi there, When I deploy my app to the iPhone for testing, I get the following error: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the Please ensure that the certificates used to sign your app have not expired. If this issue persists, please attach an IPA of your app when sending a report to Apple. executable is no longer valid.) My account was mistakenly deactivated by Apple last month. After appealing, Apple restored it at the end of last month. Currently, my Apple Developer account seems to be working fine. Today, I recreated the developer certificate and identifier, added the account in XCode, everything seemed fine, and I clicked the XCode button (Start the active scheme). The build was successful, but I got the error: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the executable is no longer valid.) Both my certificate and identifier were created just a few hours ago and show no issues. Before my account was deactivated, everything was working fine. I used a regular non-Apple developer account in XCode and performed the same steps, and it worked fine. I looked at relevant posts on the forum and tried the suggestions, but none of them solved my problem.

I'm experiencing an issue with a custom font not loading properly in Xcode 16.3. The font files are included in the bundle, listed in Info.plist, and verified for correct names using UIFont.familyNames, but they still don't appear at runtime. Has anyone else run into this with Xcode 16.3? Could this be related to recent changes in asset packaging or font catalogs?

with iOS 18.4. I and my colleagues are unable to launch the app. and with the xcode error error.txt
