Today when I went to add a package via SPM in Xcode 16.0, the "Recently Used Loading..." spinner ran and never stopped. I could not add any packages. The packages I am loading are remote and not from my own repo. I did a "Refresh Account" via the right-click which then shows items in my own hosted repo (for both Bitbucket Cloud and Github), but "Recently Used" just loads forever and there is no way to add a package.
I tried all of the usual cache deleting to no positive outcome. I saw that others had to reinstall Xcode which I am loath to do. I wound up executing defaults delete com.apple.dt.Xcode which of course made me lose all of my settings, but that did correct the problem. At least I thought it did. However, after getting everything reset, it stopped working again with the above issue.
In short, I found the issue is with Bitbucket Cloud. If I remove this account from Xcode, SPM works as normal. Add it back (all credentials are 100% fine) and I can no longer use SPM.
Does anyone know why Bitbucket Cloud is now breaking SPM and more importantly what can be done to have this account but also have a functioning SPM?

I'm running in a very very very weird error. I have a large asset catalog, consisting of about 2700 assets for 1.19GB of size.
I can successfully build and run my project with both release and debug scheme, when a real device or simulator is selected. However, whenever I select Any iOS device (arm64), about 80ish seconds in the build process, the building fails with the following output:
CoreUI: Error: unable to add asset to store
*** Terminating app due to uncaught exception 'IBPlatformToolFailureException', reason: 'The tool closed the connection (AssetCatalogSimulatorAgent)
What I tried and failed:
Cleaning DerivedData and restarting PC
Building the same project on three different devices, each with a different version of XCode. All failed.
running sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
Scanning for duplicate image files, found none.
Scanning for duplicate .imageset folders in different folders, found none.
Scanning for images that declared a different format than theirs, eg .webp renamed as .png, and found none.
Creating an empty Hello World project, and just adding my asset catalog. Build fails for Any iOS device, succeeds for simulator or physical device.
Uninstalling and reinstalling XCode command line tools.
Manually compiling via actools.
Changed "Embed Assets Pack in Product Bundle" from No to Yes.
I don't have any .svg file in my assets.
What I tried and failed but gives more insight:
Now the only thing that I was able to come up with was deleting folders to narrow down where the problem was. So I found that there is a 700MB folder called T, containing T1, T2, ..., T6. Eventually managed to narrow down even more to T3, T4, T6.
I created a distinct .xcassets catalog for each subfolder and tried to compile individually with actools, along with assets.xcassets (the main one). Here's the thing:
T3.xcassets + assets.xcassets compiles
T4.xcassets + assets.xcassets compiles
T6.xcassets + assets.xcassets compiles
T3.xcassets + T4.xcassets + assets.xcassets compiles.
T3.xcassets + T6.xcassets + assets.xcassets compiles.
T4.xcassets + T6.xcassets + assets.xcassets compiles.
T3.xcassets + T4.xcassets + T6.xcassets + assets.xcassets crashes with CoreUI: Error: unable to add asset to store.
I've been stuck for days now and can't deploy my finished app I worked on for the last three years because of this.
Will RC be allowed to upload to App Store Connect?
I have tried a couple of times with 17A321 and I keep getting unsupported SDK or Xcode version.

Everytime when iOS simulator is launched I het a lot of repeated "*** quit unexpectedly" alerts.
Where "***" is a mix of "managedappdistributiond","healthappd", and "findmylocated"
Even after the simulator is launched I still het random "*** quit unexpectedly" alerts.
Very annoying because the alerts deactivates the active window
This is on an MacBook Pro M3 Max,, Xcode 15.2, Sonoma 14.2.1, it also happens with Xcode 15.1
A co developer (MacBook Pro M1 Max,Xcode 15.2, Sonoma 14.2.1) does not have the issue
Any idea how I can prevent this from happening?
Update
Every mentioned service crash happens in libswiftCore.dylib at

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:
The Files app in the iOS 18 beta simulator appears to be read-only. I am unable to:
create folders
copy files into it by dragging them from macOS
safe files from safari
I have been unsuccessful at finding a way to popular any file or folder in the Files app which is preventing me from testing some scenarios in my app where I import files using the files sheet.
The earliest I tried was beta 3 and it still persists in beta 7. The iOS 17 simulator works fine in comparison.
My mac is a 2019 macbook pro running Sonoma 14.5.
To reproduce:
New folder
Launch Files app in iOS simulator
Tap into "On my phone"
From the top menu tap "New Folder"
(nothing happens)
Download a file
Launch safari
Find a file like a PDF to download
Tap on the down arrow in the toolbar
Files opens up with the filename in the textfield at the bottom
The "Save" button is grayed out.
Copy from macOS
Open the Files app in iOS and browse to a local folder
drag a file from the macbook onto the simulator
the sheet appears with the filename in the text field
The "Save" button is grayed out
Ok, I'm going crazy here. I have a static library for iOS that I want to build for the simulator. I use xcodebuild -destination="iOS Simulator" and then check the library using otool which tells me the platform is 6, which is Mac Catalyst.
When I look at the output of xcodebuild, it says
--- xcodebuild: WARNING: Using the first of multiple matching destinations:
{ platform:macOS, arch:arm64, variant:Mac Catalyst, id:00006041-0008492E3AA1801C, name:My Mac } ...
It has the simulator listed too, way down the list:
{ platform:iOS Simulator, arch:x86_64, id:AB7A99B3-8D24-4F73-A42D-9BB45321928D, OS:18.6, name:iPad (A16) }
When I put all of that into xcodebuild for the platform, it still says there are multiple matching destinations and chooses Mac Catalyst. Why? How? What? Does platform="iOS Simulator" mean nothing? How in the world does "Mac Catalyst" match "iOS Simulator"?????
I don't want Mac Catalyst, I don't need Mac Catalyst, and I can't get rid of Mac Catalyst. Nothing I specify in xcodebuild results in anything I can build that will compile for the simulator.
What the heck am I doing wrong?
I have an iOS app with a QuickLook extension. I also added Apple Vision Pro in the target's General > Supported Destinations section. About one year ago, I was able to run the app on iPhone, iPad and Apple Vision Pro Simulators.
Today I tried running it again on Apple Vision Pro with Xcode 26.0.1, but Xcode shows this error:
Try again later. Appex bundle at ~/Library/Developer/CoreSimulator/Devices/F6B3CCA8-82FA-485F-A306-CF85FF589096/data/Library/Caches/com.apple.mobile.installd.staging/temp.PWLT59/extracted/problem.app/PlugIns/problemQuickLook.appex with id org.example.problem.problemQuickLook specifies a value (com.apple.quicklook.preview) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point.
I tried again later a couple times, even after running Clean Build Folder Immediately, without any change. I can reproduce this with a fresh Xcode project to which I add a Quick Look Preview Extension and Apple Vision Pro as a supported destination. The error doesn't happen when running on Apple Vision Pro (Designed for iPad) or iPad Pro 13-inch (M4) destinations. What is the problem?
I created FB20448815.
Is anyone else having trouble with the Documentation in the latest Xcode beta? I can't get any UIKit documentation to appear. UIKit is completely missing from the table of contents too. I've tried deleting the documentation caches but it isn't helping.

I'm working on a macOS app that I want to give "Full Disk Access". When I run from Xcode, I get "permission denied" errors when reading a file in my home directory.
What can I do so that I can run and debug from Xcode?
I dragged the binary from the derived data folder to the System Preferences list for Full Disk Access, but that seems to do nothing.
I have a multi target project where every target relies on a built "web bundle" which is basically a collection of html, optimized images, and optimized javascript.
Right now that web bundle is built in a pre build step by running a script. The script takes awhile to run and outputs to a folder that is referenced into the project via a PBXFileReference which is then referenced in the Copy Bundle Resources step.
96516AC22BF928DD00576562 /* build */ = {isa = PBXFileReference; lastKnownFileType = folder; name = build; path = "../web-ui/build"; sourceTree = "<group>"; }
....
96516AC32BF928DD00576562 /* build in Resources */ = {isa = PBXBuildFile; fileRef = 96516AC22BF928DD00576562 /* build */; };
As a step, I wrote an aggregate target that can also run this script. I specified its input and output files and turned off sandboxing. It does exactly what I need it to. Critically it is ran based on dependency analysis. If I modify any file in web-ui it rebuilds, if I dont I can repeatedly build the aggregate target and it will not re-run the script. This is perfect.
A97590172E419CBA00741928 /* Build Web Bundle */ = {
isa = PBXShellScriptBuildPhase;
buildActionMask = 12;
files = (
);
inputFileListPaths = (
);
inputPaths = (
"$(SRCROOT)/xcodescripts/build-web-bundle.bash",
"$(SRCROOT)/web-ui/index.html",
"$(SRCROOT)/web-ui/vite-env.d.ts",
"$(SRCROOT)/web-ui/vite.config.ts",
"$(SRCROOT)/web-ui/tsconfig.json",
"$(SRCROOT)/web-ui/stats.html",
"$(SRCROOT)/web-ui/postcss.config.js",
"$(SRCROOT)/web-ui/package.json",
"$(SRCROOT)/web-ui/justfile",
"$(SRCROOT)/web-ui/src/",
);
name = "Build Web Bundle";
outputFileListPaths = (
);
outputPaths = (
"$(SRCROOT)/web-ui/build/",
);
runOnlyForDeploymentPostprocessing = 0;
shellPath = /bin/sh;
shellScript = "exec \"${SCRIPT_INPUT_FILE_0}\"\n";
};
You may notice I reference a src file. This is made possible via a flag USE_RECURSIVE_SCRIPT_INPUTS_IN_SCRIPT_PHASES which allows Xcode to check folder dependencies recursively.
The problem is that my other targets do not automatically recognize that they need to run the "WebBundle" aggregate target in order to update a resource they copy in their "Copy bundle resources" phase.
So I tried adding it as a Target Dependency.
A9DE685B2E41C9A8005EF4E0 /* PBXTargetDependency */ = {
isa = PBXTargetDependency;
target = A97590132E419C1200741928 /* WebBundle */;
targetProxy = A9DE685A2E41C9A8005EF4E0 /* PBXContainerItemProxy */;
};
Unfortunately this breaks whatever magic was allowing the script to be run only when there are web bundle changes. Every build it runs the "Build Web Bundle" script.
I think what I am missing is a way to specify in these other targets that a resource they are used to copying from the Xcode PBXFileReference is produced by the aggregate target. This way they can start to reason about the dependencies.
Other possibilities are that I should be building the web bundle to a separate location. Or that these references are somehow broken in another way. To be clear the folder format is as thus
project/
iOS/
client.xcodeproj
web-ui/
build/ (web bundle build is output here and referenced relatively)
src/
index.html (and other things)
I'm trying to update the icon of my app for watchOS 26, and I'm having troubles providing both a layered Liquid Glass icon for watchOS 26 users and a pre-rendered bitmap icon (in various sizes) for watchOS 11 and older users. Whatever I do; I either get a blurry, scaled-down watchOS 26 icon on watchOS 11; or watchOS 11's bitmap icons on watchOS 26.
While I could get the wanted result on macOS 26 and iOS 26, I simply can't get an equivalent result with watchOS 26.
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! 😀✌️
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?
Hi everyone,
I’ve run into a strange issue while building my app with Xcode 26 beta 6 (targeting iOS 26). When I include an app icon created using Icon Composer, the build time jumps to over 5 minutes. During this time, I noticed that a utility called AssetCatalogSimulatorAgent is consuming a significant amount of CPU.
If I remove the Icon Composer-generated icon from my target, the build completes in about 40 seconds. This behavior is consistent across multiple builds.
Has anyone else experienced this? Is there a known workaround or optimization for icons created with Icon Composer? I’d love to keep using the new icon format, but the build time is becoming a real bottleneck.
Thanks in advance!
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() {
					super.viewDidLoad()
	var container = SamplePackageDataStack.shared.persistentContainer
print(container)
		}
}
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.
dSYM size became thrice for builds generated via xcode 26 compared to xcode 16. These are all release builds.
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.

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
