For some reason, I have to build my iOS app project on target My Mac(Designed for iPhone) instead of using Mac Catalyst.
Now I want to access these window buttons, is there any possible way to do that? or print current view/components whatever it is while clicking button?

Hello,
in my Mac Catalyst app, I have detail view with sections modeled as DisclosureGroups. The label view has a button, that shall trigger a file import view when pushed. The label view is defined as follows:
swift
HStack {
Text(LocalizedStringKey("Documents")).font(.title)
Spacer()
Button {
showFileImporter = false
// fix broken picker sheet
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
showFileImporter = true
}
} label: {
Image(systemName: "doc.badge.plus")
.padding(.horizontal, 10)
}
.disabled(!expanded)
.fileImporter(
isPresented: $showFileImporter,
allowedContentTypes: [.data],
allowsMultipleSelection: false) { result in
// add fileUrl.startAccessingSecurityScopedResource() before accessing file
NSLog("\(result)")
}
}
Unfortunately the file import view is not showing, when the button is pushed, although the state changes to true.
Does anybody have any hints?
BTW the repo is available at https://github.com/thbonk/repti/tree/ui-refactoring
The view in question is https://github.com/thbonk/repti/blob/ui-refactoring/Repti/Source/UI/Views/IndividualDetails/DocumentsSubview.swift
Thanks & Best regards

I have an iOS app that uses os_signpost API for instrumentation.
When I profile it from Xcode on real iOS device, it works as expected.
When I profile its macCatalyst variant (using the identical code) on the same Mac where Xcode is running, the os_signpost Instrument does not show anything, not even the Apple provided signposts that are otherwise visible on the iOS.
How do I make it work?

In Xcode 15 beta 6, building any Mac Catalyst project will encounter the following Linker warning.
ld: warning: building for 'macCatalyst', but linking in dylib (/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa.tbd) built for 'macOS'

Hello,
We've an iOS application that can be launched on macOS (with the "designed for iPhone" available with Catalyst).
This application request authorization on MPMediaLibrary and play MPMediaItem with an audio player. After accepted, the authorization status is well flagged as .authorized
I can browse all MPMediaItem without issue and display them in my app.
But, when it comes the time to convert the MPMediaItem file's URL in AVAudioFile with:
AVAudioFile(forReading: fileURL)
We got 2 warnings in the console:
ExtAudioFile.cpp:211 about to throw -54: open audio file
AVAEInternal.h:109 [AVAudioFile.mm:135:AVAudioFileImpl: (ExtAudioFileOpenURL((CFURLRef)fileURL, &_extAudioFile)): error -54
We finally get an exception with this error:
Error Domain=com.apple.coreaudio.avfaudio Code=-54 "(null)" UserInfo={failed call=ExtAudioFileOpenURL((CFURLRef)fileURL, &_extAudioFile)}
This working perfectly on iOS and iPadOS, but with Catalyst we always got this error whatever the audio (from iTunes library) we try to play.
Why do we have this permission issue only on macOS ? There is something different to do to get permission on macOS ?
thanks !

I recently updated to macOS Sonoma 14.4 and now UIDevice.current.batteryLevel is always 0.
Code to reproduce:
import SwiftUI
struct ContentView: View {
@State
private var monitoringEnabled = UIDevice.current.isBatteryMonitoringEnabled;
@State
private var batteryLevel = UIDevice.current.batteryLevel;
var body: some View {
VStack {
Text("Battery Monitoring Enabled: " + String(monitoringEnabled))
Text("Battery Level: " + String(batteryLevel))
Button("Toggle Monitoring") {
monitoringEnabled = !monitoringEnabled;
UIDevice.current.isBatteryMonitoringEnabled = monitoringEnabled;
batteryLevel = UIDevice.current.batteryLevel;
}
}
.padding()
}
}
Run the above on a macOS 14.4 target, click "Toggle Monitoring", and you'll see battery level is reported as 0:
I also see the following error in my app logs when running on macOS 14.4:
Error retrieving battery status: result=-536870207 percent=0 hasExternalConnected=1 isCharging=0 isFullyCharged=0
This code displays the expected battery level when running on an actual iOS device:

I am adding Group Activities integration with a MacCatalyst app. I have added the Group Activities entitlement in Xcode. I also checked the entitlements with :
codesign --display --entitlements :-
I can see the entitlement :
<key>com.apple.developer.group-session</key><true/><key>
The feature work fine on iPadOS but when I run it on MacOS, the GroupActivitySharingController is not loading properly. I get the following error messages:
Cannot run query EXQuery: extension point com.apple.groupactivities platforms: 6 with error: (null)
Failed to lookup extension with query EXQuery: extension point com.apple.groupactivities platforms: 6 on <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980>

Failed to build remote hostViewController for <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250>
Failed to fetch extensionViewController
Calling -viewDidAppear: directly on a view controller is not supported, and may result in out-of-order callbacks and other inconsistent behavior. Use the -beginAppearanceTransition:animated: and -endAppearanceTransition APIs on UIViewController to manually drive appearance callbacks instead. Make a symbolic breakpoint at UIViewControllerAlertForAppearanceCallbackMisuse to catch this in the debugger. View controller: <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250>
I got a similar error on iPadOS when the entitlement was not added. Now that I have the entitlement, the error appears only on MacOS.
Does MacOS/MacCatalyst use a different entitlements file? What could be cuasing this?

Preparing an iPad App for native MacOS experience using Mac Catalyst (and AppKit when needed) and using SwiftUI.
We observe that Horizontal Scroll is tricky using a Mouse! Most users have the habit of click+drag to scroll horizontally. This does not seem to be default behavior on ScrollView.
Strange: Same App when compiled on "Mac (Designed for iPad)" [aka Silicon only] scrolls horizontally with click drag. But not if compiled with Mac Catalyst.
Question: How can we enable general click-drag for horizontal scrolling using SwiftUI on Mac Catalyst? I wouldn't mind using specific AppKit framework if needed.
Thanks in advance.

Hi,
I have an imagePickerController where .allowsEditing is set to true after picking an image. I can move/scale it in iPhone/iPad simulators, but running on my Mac the scaling part of it doesn't work and I don't know how I could go about making the scaling work. Any suggestions much appreciated.
Update: I am using a Magic Mouse. No Trackpad or Touchscreeen Mac.

I have a text based action for iPhone and Mac Catalyst I am developing in Xcode 14.3.1 on macOS 13.4.1.
I have the container app, an action and an AppGroup defined.
I have confirmed that I can read the necessary shared defaults when the action launches.
At this point the UI for the action is a simple textview in which I hope to display a modified version of the text passed to the action in the NSExtensionItems.
I am not using a simulator. I am running the action directly using Xcode.
What is happening is that the ActionViewController viewDidLoad runs but no visible window opens.
In the console I see this as the action launches:
2023-07-05 18:27:23.692277-0700 XYZ[4634:279295] [ViewBridge] ViewBridge attempted to look up a hosted window with identifier 8E816BD5-67D3-402D-ADEB-AC59EDFA1F3B, but it was never registered.

....
The last line above is repeated 12 times....
Any helpful ideas would be deeply appreciated!

I wanted to post this here in the hope that this will draw attention to what I think is a serious change in behavior that could negatively affect Catalyst apps in macOS 14.4.
Prior to macOS 14.4, when the completion handler was invoked from calling dismiss() to dismiss a presented view controller in a Catalyst app, the dismissed controller no longer appeared in the chain. That is to say that if the root view controller presents View Controller A, when View Controller A is dismissed, the root view controller's presentedViewController property is nil when the completion handler for dismiss() is called.
With macOS 14.4, this is no longer the case. If the root view controller presents View Controller A and then View Controller A is dismissed, the presentedViewController property of the root view controller still refers to Controller A when dismiss()'s completion handler is called.
The side effect of this change in behavior means that if you try to present another view controller from the completion handler of the one being dismissed, it will fail to show because the top most view controller in the chain is the controller being dismissed and presenting from it will result in nothing showing up because it is removed from the chain immediately after the completion handler is invoked. Before macOS 14.4, it the top of the chain would have been the controller that presented the controller that was dismissed, which is what you actually want.
This problem does not exist in the betas for iOS 17.4 or iPadOS 17.4. It appears to affect only Catalyst apps running under macOS 1.4.4.
I think this change in behavior has the potential to affect a number existing Catalyst apps and it may not be obvious to the user something is going wrong. It really should be fixed before macOS 14.4 is released to the public.
I've created a feedback with a sample Xcode project that demonstrates the problem (feedback number FB13622757).

I experience an issue with SceneKit that is driving me crazy ;(
I have severe hangs when I disable Metal API Validation (which is default when you don't run from Xcode). So is there any way to force enable Metal API Validation for AppStore binary? (run MTL_DEBUG_LAYER=1 for Testflight or App Store)
Hangs happen on Catalyst but also on iOS if I use lightingEnvironment...

Hi,
I am trying to create a hard link on MacOS(Mac Catalyst App) between files using
[self linkItemAtURL:fromURL toURL:toURL error:&error];
Source Path for MacOS -
/var/folders/lf/dt_4nxd945jdry2241phx0_40000gn/T/net.appname.AppName/documents/...
Destination Path for MacOS -
/Users/username/Library/Group Containers/group.net.appname.AppName.shared/Message/Media/...
Although the same code works fine on iOS, but getting following error on MacOS
Error Domain=NSCocoaErrorDomain Code=513 couldn’t be linked because you don’t have permission to access, Operation not permitted
Source Path for iOS -
/Users/user/Library/Developer/CoreSimulator/Devices/B4054540-345F-4D90-A3C5-DA6E6469A3FC/data/Containers/Data/Application/B4AB7D70-491C-49E5-9A3F-27E66EC3423D/tmp/documents/...
Destination Path for iOS -
/Users/user/Library/Developer/CoreSimulator/Devices/B4054540-345F-4D90-A3C5-DA6E6469A3FC/data/Containers/Shared/AppGroup/842B248E-CCA6-4B5C-82BD-2858EADD3A90/Message/Media/...
However, interestingly if I try to copy the file, it works perfectly fine on MacOS as well. I am unable to understand if it is the permission issue, it should not work with copy as well.
Does anyone have any reason/solution to this behaviour?

We have an iOS app with a web View.
To develop and debug, we inspect the web view using Safari Dev Tools (Developer menu).
This Works: We are able to inspect the web view when the application is run on physical devices as well as on simulated devices (iPhone and iPad).
This Does NOT Work: We are not able to inspect the web view of the same app running, unmodified, on same Mac. Safari’s Developer menu says “No Inspectable Applications” against the Mac.
Requesting guidance or leads on ways to inspect and debug the app under these conditions. Many thanks!

In our mac catalyst app we access AppKit api's by using MacOS bundle(plugin).
when using CGDisplayCreateImage(_: CGDirectDisplayID, rect: CGRect) method the plugin crashes.
Implementation:
@objc
func windowMoved(_ notification: NSNotification) {
guard let win = self.window else {
return
}
let displayId = CGMainDisplayID()
let winRect = win.contentView?.convert(qrRect, from: self)
var rect = win.convertToScreen(winRect ?? self.bounds)
if let screenFrame = NSScreen.main?.visibleFrame {
rect.origin.y = screenFrame.height - rect.maxY
rect.origin.y += screenFrame.minY + win.titlebarHeight
}
guard let image = CGDisplayCreateImage(
displayId,
rect: rect) else {
return
}
guard let qrString = image.detectQRCode().first else { return }
// ...
}

It appears the app is sandboxed. I need to be able to access the broader file-system and pick a folder/file. Is this possible?
Is it possible to invoke the app with a command-line argument? If so, how is it accessed (in code)?

Hi,
Inside a Mac Catalyst app, I need to display a popover starting from an NSToolbarItem contained inside the app toolbar (like the Apple Maps Mac app does, see below image).
In order to do that, when I press the button I need to find the toolbar item view and use it as popover anchor.
How can I find the view or frame of an NSToolbarItem on Mac Catalyst?
A property that could help me is the NSToolbarItem "view" property (NSView), but that property has been marked has unavailable in Mac Catalyst.
Any idea?
Thank you

Running in a Mac (Catalyst) target or Apple Silicon (designed for iPad).
Just accessing the playbackStoreID from the MPMediaItem shows this error in the console:
-[ITMediaItem valueForMPMediaEntityProperty:]: Unhandled MPMediaEntityProperty subscriptionStoreItemAdamID.
The value returned is always “”.
This works as expected on iOS and iPadOS, returning a valid playbackStoreID.
import SwiftUI
import MediaPlayer
@main
struct PSIDDemoApp: App {
var body: some Scene {
WindowGroup {
Text("playbackStoreID demo")
.task {
let authResult = await MPMediaLibrary.requestAuthorization()
if authResult == .authorized {
if let item = MPMediaQuery.songs().items?.first {
let persistentID = item.persistentID
let playbackStoreID = item.playbackStoreID // <--- Here
print("Item \(persistentID), \(playbackStoreID)")
}
}
}
}
}

While I'm keen on being on the latest version of macOS, I'm having trouble meeting the requirement that my app can run on a version of macOS that doesn't exist :)

I was loading a URL using SFSafariViewController in my app and also implemented the SFSafariViewControllerDelegate. I noticed that when I am running my app on iOS, I am not getting the callBack in safariViewControllerDidFinish(_:) until or unless "Done" button is pressed. But when I am running it on MacCatalyst following behaviour is noticed:
default browser is launched.
I get a callback in safariViewControllerDidFinish(_:) without any of my action(like pressing "Done" button).
Is this the expected behaviour? I am curious to know why I am getting callback in safariViewControllerDidFinish(_:).
