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'm pulling my hair out here with this new Xcode 16, it complains that my app's dSYM is empty though it's clearly not, it's about 25MB. I'm working on a project using an internal static library, everything is built inhouse using swift, we own all the source code. It worked just fine until the other week, when I updated the Xcode, and now I can't debug anything. I keep getting "type for self cannot be reconstructed" when I run "po self.some_property". Why is that? The Debug information Format is set to DWARF with dSYM File for both the executable and lib projects. I've been a Unix guy since before I knew myself and I enjoy fixing things myself, down to bare metal, but man, this bug is driving me crazy. Is it even a bug?? It's the first time in more than 15 years since I started coding on Mac and iPhone when a bug has defeated me. I was always able to fix things using just the documentation and google, but the Apple toolchain is getting worse and worse nowadays. I remember the time when Apple made the complicated things simple, now they make the simple things complicated :( I just split the static lib from the main project one year ago, because of the ridiculously long build time. Should I merge back all the code in a single project? Something seems wrong to me. So I created this account to ask the masters. How can I get back my debug info (and sanity)? Using Xcode 15 is not an option because it doesn't run on Sequoia.

How do I resolve these errors reported in Xcode about using Core Data Composite Attributes feature? Composite Attributes feature requires tvOS deployment target 17.0 or later Composite Attributes feature requires watchOS deployment target 10.0 or later My app is a Cocoa app and targets macOS 14.0+. I do not have an iOS, iPadOS, tvOS nor watchOS targets. So, I don't understand why I am getting these errors. My Xcode project format is set to Xcode 16.0. I am on macOS Sequoia 15.2 (24C101) and using Xcode Version 16.2 (16C5032a). If you create a new Xcode project and choose macOS > App and Storage > Core Data and then Add Composite Type and set an attribute name and type, you will get the errors.

I'm getting hundreds of the message below in Xcode. I've narrowed it down to when I instantiate the following AVAudioUnitComponentManager.shared() Message send exceeds rate-limit threshold and will be dropped. { reporterID=231700600717315, rateLimit=32hz }

I am experiencing an issue with Xcode 16.2 (15E204a) where global workspace search does not return results from .xib files.

Whenever I run anything in xcode it opens an extra terminal that runs the program then exits immediately, but the app still runs through the normal xcode launch. It's not a huge issue but It's getting really annoying to realize I have like 7 windows of terminal open that are just doing nothing. Has anyone had this issue before?

I have a sample SwiftUI iOS app. As shown in the screenshot below, my project has three configurations: Debug, MyDebug, Release. If I select the Debug or MyDebug scheme, I get a preview. But if I select the Release scheme, I get an error that says the following. ”***.app” needs -Onone Swift optimization level to use previews (current setting is -O) , where *** is the app name. It probably has nothing to do with the Preview error, but the Info.plist has a dictionary such that the key name is devMode, and the value is $(DEVMODE). And I have a user-defined setting as shown below. My ContentView has the following. import SwiftUI struct ContentView: View { @State private var state: String = "" var body: some View { VStack { Text("Hello, world!: \(state)") } .onAppear { if let devMode = Bundle.main.object(forInfoDictionaryKey: "devMode") as? String { print("Development mode: \(devMode)") state = devMode } if let path = Bundle.main.path(forResource: "Info", ofType: "plist") { if let dict = NSDictionary(contentsOfFile: path) { print("**** \(dict)") } } #if DEBUG print("Debug") #elseif MYDEBUG print("MyDebug") #else print("Que?") #endif } } } #Preview { ContentView() } So my question is how I get the preview for all three build schemes? Muchos thankos.

I'm on version 16 of simulator and Xcode. Last Friday, starting the simulator would take 10 seconds at the most. Now, it takes at least 10 minutes. My app target is the same and nothing in my app itself has changed. There's no new software installed and it has plenty of RAM and disk. When I target my phone, it is instant. So I'm testing / debugging everything on my phone now. When I use the simulator, the initial load is about 10 minutes, then it's fine (using the app itself). But something is causing it to hang when loading. And like I said - last week it was fine. If it was slow when running on my phone, I'd think it was something with me/the app. But it's not. This is the only messages I get in the system log. Feb 24 12:54:46 MacBookAir bootlog[0]: BOOT_TIME 1740423286 329039 Feb 24 13:06:42 MacBookAir syslogd[2095]: Configuration Notice: ASL Module "com.apple.contacts.ContactsAutocomplete" claims selected messages.

When renaming a variable in the active scheme, it's not renamed for the non active ones. As a result when you have code that operates in both schemes (with #if os() conditions) a compile time error is introduced. Is this an Xcode bug or expected behaviour?

I can‘t use breakpoints on the simulator after updating Xcode and the simulator. I can use breakpoints on a physical iPhone. I tired to download other iOS simulator version, but still not working. Both SwiftUI and UIKit not working.

I have had content blockers in the Mac App Store for years. Ever since moving to Sonoma, doing a clean build or archive in XCode deletes the extension from Safari settings since it never gets into the built app. The only way for me to get it back is to remove the DerivedData and target, reboot, and create a target with a different name. That works and stays around in Safari settings as long as I only build and don't clean. However, a clean or an archive removes it again. Restoring a version of the project from Time Machine that was posted to the App Store weeks or months ago doesn't work. However I can download the version of the app in the App Store, and it works, but I can't build it now from the source code that was used to build that version without going through the above process. Moving from Sonoma 14.7.1 to 14.7.2 didn't work. I would move to Sequoia if I had reason to believe that would work, but I don't. Safari 18.2, Sonoma 14.7.2, 32GB, 2.2 GHz 6-Core Intel Core i7

Beginning April 24 releasing on the App Store requires using Xcode 16, iOS 18 SDK. https://developer.apple.com/news/upcoming-requirements/?id=02212025a Xcode only offers simulators for iOS 15. I had not been able to install and use previous versions. Does it imply iOS 15 is the minimum target allowed?

Hello, I'm trying to use Xcode's ARKit Session replay functionality. I have a capture I made using Reality Composer and when trying to use it with Xcode's replay functionality the installation and debugging process seems stalled forever. I've gotten it to work once so I know the capture file is functional but I have never gotten it to work a second time, even though I didn't change any settings. No amount of restarting Xcode, the Mac, or the iPhone seem to work. I have also tried cleaning build folders, reinstalling the app, and clearing DerivedData. I can confirm from the Xcode logs that the app installs correctly but the app never launches. If I unselect the checkbox for "ARKit Replay Data", the app launches and debugs nearly instantly. I have tried letting it "attach" for up to 10 minutes to no avail.

We are using XC Test case framework for the unit test cases after running test cases the code coverage is not visible. In previous version of Xcode it was working properly (like Xcode 15 and earlier).

Hi there, I uploaded an update bundle for the posted app, but I got a rejection message. ITMS-90048: This bundle is invalid - Your archive contains paths that are not allowed: [._Symbols] The XCode version I'm using is 16.2, and I've been trying to find a route using Run Script and Finder, but I don't know what the hell it is about. Does anybody know what could cause this issue? Any help would be appreciated. Thanks.

I can't get my app's logo to show in the "About" box nor in the app switcher. I have: created "Assets.xcassets" created "AppIcon" added 10 image files of the logo to the AppIcon image well [? right terminology ?] saved and built the project – there are no errors or warnings When I run the project, I still get the default image showing in the About box and in the app switcher. Because first attempt failed, I changed "applet" to "AppIcon" in "App Icons and Launch Screen" in "General" settings. That did not change the result. I also toggled "Include all app icon assets" which also did not change the result. Weirdly, my app's logo DOES show beside the app name in every item of "Build Settings". Do I need to do something else to change the default image in the "About" box ? Thanks. [Xcode 16.2 on macOS 15.3.2.]
