Xcode 16 unindents lines if I choose a code-completion and I cannot find a way to stop this - does anybody know how to stop it? Here's a link to a gif demonstrating this problem - it's incredibly frustrating. https://i.imgur.com/jaDpzpb.gif Thanks in advance

I have a very annoying problem when I try to distribute my app to the App Store. Organizer does not recognise the project as an app I think. Xcode version is 16.2 but I have tries in 15.4.

Hi folks, was there an unannounced breaking change in Xcode 16.3 regarding the device types, e.g. "iPhone 16 Pro.simdevicetype"? We consume Xcode simulators viaa CLI that uses it and the absence of it broke the complete setup. We are filing a bug report in parallel, but maybe someone is experiencing something related and may see a workaround. Thanks to everyone!

I updated to Xcode Version 16.3 (16E140) on macOS Sequoia 15.3.2 (24D81). I noticed the contextual menu is missing the Copy submenu. This submenu is accessible from the Main Menu under Edit menu. You can see that the contextual menu is missing the Copy submenu, it was there prior to Xcode Version 16.3 (16E140). Why was it removed? Could this Copy submenu be restored in future updates, please?

After installing the latest version of Xcode (16.3, 16E140), I get many instances of this error when building my app: Error: Multiple parameters detected in phrase. A single phrase can only use a single parameter. Here is an example of an App Shortcut that is causing this error: AppShortcut( intent: SelectModelIntent(), phrases: [ "Select \(\.$model) in \(.applicationName)", ], shortTitle: LocalizedStringResource("Select Model", comment: "Title for Shortcut"), systemImageName: "rectangle.3.group" ) If I replace the application name parameter with a hard-coded string, I get an error that says I need to have the application name parameter in each phrase. So is it not possible to have any other parameters in a phrase besides the application name? That seems unlikely to me.

Hello, I am trying to take a computing class. I have a macbook air running big sur (I cannot update it past that). I was told for the class that Big Sur would be sufficient. It appears that I don't have xcode however and I need it on my computer. I cannot find any version to download from Apple besides the newest- which isn't compatible with Big Sur. I have found some older versions online but I don't know what to trust. I was told I could download it here but am not finding it. I think I need one of the versions in the 11s Please help!

This code was compiling fine on Xcode 16.2 public var hasSecureHardware: Bool { let isSimulator = TARGET_OS_SIMULATOR == 1 return !isSimulator && isAvailable } However, now the build breaks with the message: Cannot find 'TARGET_OS_SIMULATOR' in scope

Hey iOS Dev's, I’m currently working on a Swift Package Manager (SPM) for WireGuard, originally developed by a previous team member. It was working fine in Xcode 15.2, but after upgrading to Xcode 16 and Swift 6, I need to update the SPM to ensure compatibility with my base projects and other projects relying on it. With Apple making Xcode 16 mandatory for app submissions starting April 24, this has become an urgent issue. I’ve searched extensively but haven’t found a working solution yet. Has anyone faced similar challenges with Swift 6 migration and SPM updates? Any insights, best practices, or debugging tips would be greatly appreciated! Let’s connect and collaborate—I’d love to discuss possible solutions! 😊 #iOSDevelopment #Swift6 #Xcode16 #SPM #WireGuard #iOS #Swift #SoftwareEngineering #AppStore

Use a project hosted by a filesystem/local Git repository. Make changes to any file in the project. Switch to the "Source Control" Navigator, and the "Changes" sub-navigator within that. Select "Uncommitted Changes", or any file below that. Verify that your changes appear in the source change browser/editor on the right. Click the "Stage All" button. Absolutely nothing happens, 90% of the time. Go back to the Changes navigator, right-click on an item there and select the "Stage Changes in..." popup menu item. It works, every time. I haven't found any pattern to the 10% of the time the "Stage All" button actually works, wrt what changes are selected in the navigator, whether I've already typed a commit message, etc.. I happen to be using Xcode 16.0 on two Macs: a Mac Studio running MacOS 14.6.1, and a 2019 MacBook Pro running MacOS 14.7.1. Both exhibit the same symptoms.

crashlog.crash How do I understand this bug report ? It is ARM Assembly code with a crash of an iOS Library : libobjc.A.dylib. I do not know ARM Assembly code. This happens just after SceneDidDisconnect . If i put 'exit(0)' in SceneDidDisconnect , there is no crash. In the crash log we set that IOS trys to terminate my App but it can not.

Hi, upgraded to Xcode Version 16.3 (16E140) today and now Playground can't execute JSON decoding. The code below is taken from Apple's own JSONDecoder example: struct GroceryProduct: Codable { var name: String var points: Int var description: String? } let json = """ { "name": "Durian", "points": 600, "description": "A fruit with a distinctive scent." } """.data(using: .utf8)! let decoder = JSONDecoder() let product = try decoder.decode(GroceryProduct.self, from: json) print(product.name) // Prints "Durian" This use to work in the previous Xcode version. Now I get this error: The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. This file doesn't exist in the location. I've restarted Xcode and the Mac, same error. Any thoughts?

I have a project which contains local packages. One of the packages has an explicit dependency on package A, but the main project also has the same dependency. Both of them are pinned to the exact version at all times. Should I manage "shared" dependencies at the project level for local packages? This seems counter intuitive at first, but this question is originating from me fighting with a "Build service could not create build operation: unable to load transferred PIF: The workspace contains multiple references with the same GUID" error in Xcode 16 (all versions). It happens when I switch branches. Closing and reopening Xcode does resolve the issue, but it's a real flow killer. The guide below doesn't mention dependency graph best practice. https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages Thank in advance.

Within Xcode's settings location section is a drop down menu to switch between setting the derived data location to be default, relative or custom. However its a global setting. I work on more than one project simultaneously, and for one of them I want the location set to relative, but default for all the others. Is there any way of achieving that?

Hi All, I'll start by saying i am complete beginner when it comes to coding/ developing. So please be easy on me, im also using AI tools to help and learn so apologies if what im saying doesnt make sense. The error im getting is /Services/SupabaseManager.swift:47:29 Cannot find 'GlobalOptions' in scope From AI tells me 'GlobalOptions' is defined a types.swift file in the supabase package public struct GlobalOptions: Sendable { /// Optional headers for initializing the client, it will be passed down to all sub-clients. public let headers: [String: String] /// A session to use for making requests, defaults to `URLSession.shared`. public let session: URLSession /// The logger to use across all Supabase sub-packages. public let logger: (any SupabaseLogger)? public init( headers: [String: String] = [:], session: URLSession = .shared, logger: (any SupabaseLogger)? = nil ) { self.headers = headers self.session = session self.logger = logger } } From what i can see i have added the supabase package successfully, following this guide - https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app Here are some screenshots of my xcode to show the added package.

So I believe my machine JUST updated to Xcode 16.3 (16E140). But it definitely just installed the latest iOS simulator 18.4. However, now my preview will sometimes give me the error Failed to launch app ”Picker.app” in reasonable time. If I add a space in my code, or hit refresh on the Preview, then it will run on the second or third attempt. Sometimes in between the refreshes, the preview will crash, and then it will work again. Anyone else experiencing this? Any ideas? Thanks

Hey Apple Team! We recently updated to Xcode 16 and saw a massive memory spike, which caused "Out of memory" Mac warnings in the final stages of our app's build process. We noticed that the process responsible for this is "EmbeddedBinaryValidationUtility" (see screenshot). Is there a workaround to limit its memory usage? This is causing significant anguish for our developers.

Hi, I am able to build my iOS app successfully, developed in objective-C with iOS 17.5 SDK and Xcode 15. Due to requirement of Appstore we are trying to build with iOS 18 SDK and Xcode 16. When building getting error in LAEnvironmentState.h file: a) "Property requires field to be named" b) "Expected member name or ';' after declaration specifiers" Same app when opening with Xcode 15 gets build without any issue. Any help/suggestion would be appreciated.

Hi there, When using devicectl to manage files: It's unclear for which domains the username should be provided It's unclear how to determine the username Listing files USAGE: devicectl device info files [<options>] --device <uuid|ecid|serial_number|udid|name|dns_name> --domain-type <domain-type> FILE OPTIONS: --username <username> The username of the user we should target. Only relevant for certain domains. --domain-type <domain-type> The file service domain. Valid values are: temporary, appDataContainer, appGroupDataContainer, systemCrashLogs. You must specify a valid domain and identifier pair. Certain domains must be accompanied by an identifier that provides additional context. For example, if the domain is an app data container, the identifier is the bundle ID of the app. For temporary directories, the identifier is a unique client-provided string which is used to get your own space, separate from those of other clients. --domain-identifier <domain-identifier> A unique string used to provide additional context to the domain. --username The username of the user we should target. Only relevant for certain domains. In the domains, the username requirements are not mentioned. Copying files USAGE: devicectl device copy to --device <uuid|ecid|serial_number|udid|name|dns_name> --source <source> [--destination <destination>] [--user <user>] --domain-type <domain-type> [--domain-identifier <domain-identifier>] [--remove-existing-content <remove-existing-content>] [--verbose] [--quiet] [--timeout <seconds>] [--json-output <path>] [--log-output <path>] DEVICE OPTIONS: -d, --device <uuid|ecid|serial_number|udid|name|dns_name> The identifier, ECID, serial number, UDID, user-provided name, or DNS name of the device. FILE OPTIONS: --source <source> The item which should be copied. --destination <destination> The location to which the item should be copied. -u, --user <user> The name of the user we should target. Only relevant for certain domains. --domain-type <domain-type> The file service domain. Valid values are: temporary, appDataContainer, appGroupDataContainer, systemCrashLogs. You must specify a valid domain and identifier pair. Certain domains must be accompanied by an identifier that provides additional context. For example, if the domain is an app data container, the identifier is the bundle ID of the app. For temporary directories, the identifier is a unique client-provided string which is used to get your own space, separate from those of other clients. --domain-identifier <domain-identifier> A unique string used to provide additional context to the -u, --user The name of the user we should target. Only relevant for certain domains. The "certain domains" are not specified. user vs username The list files command takes: --username <username> The username of the user we should target. Only relevant for certain domains The copy command takes: -u, --user <user> The name of the user we should target. Only relevant for certain domains. Is there a difference between username and user? How do we figure out the user or username? From https://developer.apple.com/forums/thread/749649 I learned that about the "mobile" value, but why, and how? It would help if these arguments could be explained in more detail.

I don't know Xcode very well, and had been using it sporadically to test a project exported from Unity. I recently added a StoreKit Configuration to the project, and since then it gives me ≈10s after launching before the beach ball appears, and it never leaves. Xcode says it is "Indexing" but I don't know if that's an obvious culprit. I can still build my project via the fastlane tool, on the command line, and the newly-added StoreKit configuration works just fine. But I cannot use Xcode interactively any more, unless I re-export the project from Unity. The only difference between it working and hanging is the Store Kit configuration. How do I understand what's going on, and (ideally) fix it? The Activity Monitor gives a bunch of backtraces that don't have an obvious network or I/O culprit in them.
