I am having issues loading my model from a Swift Package with the following structure: | Package.swift | Sources | - | SamplePackage | - | - Core | - | - | - SamplePackageDataStack.swift | - | - | - DataModel.xcdatamodeld | - | - | - | - Model.xcdatamodel ( <- is this new? ) As mentioned, I am not required to list the xcdatamodeld as a resource in my Package manifest. When trying to load the model in the main app, I am getting CoreData: error:  Failed to load model named DataModel Code: In my swift Package: public class SamplePackageDataStack: NSObject {     public static let shared = SamplePackageDataStack()     private override init() {}     public lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: "DataModel") container.loadPersistentStores(completionHandler: { (storeDescription, error) in             if let error = error as NSError? {                 fatalError("Unresolved error \(error), \(error.userInfo)")             }         })         return container     }()     /// The managed object context associated with the main queue. (read-only)     public var context: NSManagedObjectContext {         return self.persistentContainer.viewContext     }     public func saveContext () {         if context.hasChanges {             do {                 try context.save()             } catch {                 let nserror = error as NSError                 fatalError("Unresolved error \(nserror), \(nserror.userInfo)")             }         }     } } Main App: import SamplePackage class ViewController: UIViewController { override func viewDidLoad() { &#9;&#9;&#9;&#9;&#9;super.viewDidLoad() &#9;var container = SamplePackageDataStack.shared.persistentContainer         print(container) &#9;&#9;} }

From time to time while I'm editing code, Xcode 15.0.1 says "The file 'project.xcworkspace' has been modified by another application" asking me "Keep Xcode Version" or "Use Version on Disk". I didn't see this before 15.0.1 (or 14.1.1). Who changed the file? What should my answer be? Thanks.

I have spent nearly an hour trying to get my iPhone 7 with iOS 15.8 to be recognized within xCode 26. I did not have this issue with the previous version of xCode. I have tried rebooting my Mac, rebooting my iPhone 7, removing the iPhone 7 from the list of devices that belong to my account, verified that I have support files for iOS 15.8 installed, signing out of my Apple account and signing back in....nothing works. Every time I go to "Windows > Devices" I see the iPhone 7, but I get a never-ending spinning circle next to the iPhone 7 (which is shown as connected) along with a banner that says "xCode will continue when Joe's iPhone 7 is finished." I can leave the phone connected to my Mac for an hour, and this message and the spinning circle next to the iPhone 7 never changes.

dSYM size became thrice for builds generated via xcode 26 compared to xcode 16. These are all release builds.

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 am trying to run Xcode 15 on macOS 15.4. As we need to build framework with older versions of Xcode. Any work around for it?

I am at a loss as to why, since the latest update, that my preview pane is no longer working. May i have some assistance on the matter? Thank you in advance! 😀✌️

After updating to 16.3, my project now fails to compile with the diagnostic: "Command SwiftCompile failed with a nonzero exit code". This is a SwiftUI document project with two local packages, the second of which is a rather large one with 112 SwiftUI files. It is this second package that is failing. There are no issues when compiling with 16.2. Without diagnostics I'm having a bit of difficulty in determining the cause. My thought is to regress the commits unit 16.3 gives a success, or shows issues. Although I'm not catching a similar issue in the forums, I'm seeing other problems with 16.3. Has anyone else had such build failure isolated to 16.3? Any advice on other ways to approach this problem? Thanks in advance

Hi! I´m new developing in this app, I have a problem. The preview screen is showing me the image bellow, There is no other response, I dont know what could happened. Thanks!

I have a very large terminal project that relies on the ncurses library. As of the update on Dec. 11, 2024, the ncurses (and forms) API's no longer work when the app is launched from Xcode. If I run the app by double-clicking on the executable from Finder, the API's work as expected - but of course, that does not allow for debugging - which is the purpose of running within Xcode. I have tested on a simple project that simply outputs "Hello World" and waits for the input of CR before ending. What should happen, is that "Hello Word" is output on the terminal, but instead no output occurs. I stress that everything worked prior to the update on Dec.11. The code for main is simply this: #include <iostream> #include "stdlib.h" #include "stdio.h" #ifdef __cplusplus #include <iostream> #endif #include <cassert> #include <ncurses.h> #include <form.h> using namespace std; int main(int argc, const char * argv[]) { // cout << "Hello, World!" << endl; // Basic test initscr(); printw("Hello World !!!"); refresh(); int ch = 0; while (ch != 10) { ch = getch(); } endwin(); return 0; } To link to libncurses.tbd, in Build Phases, add the libncurses.tbd from the list of Frameworks. To output on the terminal, select the Product menu item in Xcode, then Edit Schema. Under the Options tab, change the Console selection to Terminal. When the application runs, the terminal will launch, but no output will occur. I have Googled every topic imaginable for 2 days now but have not come up with a solution. Is there something that I need to update? It looks to me like the libraries have been updated on Dec. 11 as well, but is there something else I need to do? For a more detailed image of one of the many screens I have working prior to this issue:

Every time my app runs in the simulator I see this error: Warning: Error creating LLDB target at path '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app'- using an empty LLDB target which can cause slow memory reads from remote devices: the specified architecture 'arm64--' is not compatible with 'x86_64-apple-ios13.2.0-simulator' in '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app/Babylist' What is this? I'm on an M1, no build issues. It makes me think the simulator is running under rosetta with x68_64. But I didn't choose to do that. Mac OS Ventura. Xcode 14 RC.

I downloaded the Xcode Beta 3 on my MacBook Pro M4 Base today and tested out some iOS26 mechanics of my app. And when I came back to my main Xcode to continue developing in iOS18, I couldn't build my app. I went to Product &gt; Destination &gt; Manage run destinations and then tried to create a simulator with iOS18 but it didn't show up, only choice that's showing up was iOS26. I tried deleting iOS18 platform and downloading it again but it didn't solve, I tried deleting Xcode Beta but it didn't solve the problem either. I deleted Runtimes folder, it didn't solve too. I can not create a simulator of iOS18 or below too, the error says "The iOS 18.5 simulator runtime is not available. Try reinstalling Xcode or the simulator runtime." How can I fix this problem?

When I update the macOS from 15.5 to 15.6, Preview error. 1、I try remove simulator cache， sdk 2、remove Xcode build cache 3、reinstall Xcode 4、try with this method https://byby.dev/uninstall-xcode#:%7E:text=Delete%20old%20simulators%20and%20devices,moving%20them%20to%20the%20Trash but all failed swiftui log.txt

Hi I've downloaded the latest version of Xcode 14.2 but when I run the app in Simulator I can only test it on iOS16.2 Is there a way to run it in 16.3?

Hi all, reposting this from here: https://unix.stackexchange.com/questions/789849/xattr-c-not-removing-com-apple-finderinfo-attribute I came to this problem because my Xcode project was failing to build due to the error "resource fork, Finder information, or similar detritus not allowed" (was trying the solutions on this post). Basically, running xattr -cr . in the terminal on my project directory removes all extended attributes except com.apple.FinderInfo, which stays on all .xcodeproj and .xcworkspace files. I've tried everything under the sun, from sudo to xattr -d to dot_clean to tar to rsync and nothing works. Is this just an immortal attribute that can never be removed? I'm truly at a loss here, this is for my senior thesis project.

Hi everyone, I recently updated to Xcode 26.0 and noticed that the “Extract Subview” refactoring option seems to be missing. Now, in Xcode 26, the only options I see under Editor -> Refactor -> are: Extract to Selection File Extract to Method Extract to Variable Extract All Occurrences But there’s no Extract Subview as there was before. Was Extract Subview intentionally removed in Xcode 26? Or is it hidden behind a new menu location or renamed?

Like so many, i am getting The operation couldn’t be completed. (ModelCatalog.CatalogErrors.AssetErrors error 1.)

I received the attached crash report. The problem is that the crash report does not contain the abort reason - it appears to be thrown in the GCD library with no additional information. Is it a possible deadlock? 2023-02-15_02-40-23.0077_+0100-94015bd052c4005658221a5e6279f28a75b9e92c.crash Any ideas?

I use spm manage swift package, now i want my macos app support arm64e,so i add arm64e in Build Srtting -> Architectures. but i got error Could not find module 'SwiftyJSON' for target 'arm64e-apple-macos'; found: arm64-apple-macos, x86_64-apple-macos Apparently, if no limit in Package.swift, SPM will only compile versions for x86 and ARM64 architectures by default. now, how should I configure SPM to compile the arm64e version? thanks

Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts
