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.
2023-07-05 18:27:23.692408-0700 XYZ[4634:279295] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set.
....
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'm using Xcode 15.2 (15C500b), targeting iOS 17.2.
I've elected to have the App Store choose the minimum version for Catalyst. I've also tried selecting a version.
ITMS-90899: Apple silicon Mac support issue - The app is not compatible with the provided minimum macOS version of 14.2. It can run on macOS 14.4 or later. Please specify an LSMinimumSystemVersion value of 14.4 or later in a new build, or select a compatible version in App Store Connect. For details, visit: ...
Is there something I could be doing wrong to prompt this behaviour?

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(_:).

Running a Process executableURL path for a Catalyst target using a macOS type bundle returns the following error as output:
(/Applications/Xcode-15.1.0.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Debugger/libViewDebuggerSupport_macCatalyst.dylib), but incompatible platform (have \'MacCatalyst\', need \'macOS\'))
Is it possible to set which dylib platform is used by the macOS bundle executable file instead of using the MacCatalyst one?

Hello,
I am working on an AUv3 extension project using SwiftUI in Xcode and have encountered a peculiar issue when implementing a simple alert on Mac Catalyst. The code is straightforward; it's merely an alert triggered by a button within a SwiftUI view. Here's the relevant portion of the code:
import SwiftUI
struct SwiftAUv3ExtensionMainView: View {
var parameterTree: ObservableAUParameterGroup
@State var showingAlert = false
var body: some View {
VStack {
ParameterSlider(param: parameterTree.global.gain)
Button(action: {showingAlert = true}, label: {
Text("Button")
})
}
.alert("Alert", isPresented: $showingAlert, actions: {}, message: { Text("Message") })
}
}
The problem arises when this alert is displayed and subsequently closed. Upon closing the alert, the cursor turns into a spinning rainbow and the app freezes for several seconds. Additionally, Xcode's console displays the warning: -[NSWindow makeKeyWindow] called on _NSAlertPanel which returned NO from -[NSWindow canBecomeKeyWindow].
I am looking for insights or solutions to address this issue. Has anyone else experienced similar problems with SwiftUI alerts in AUv3 extension projects, especially when using Mac Catalyst? Any advice or suggestions would be greatly appreciated.
Thank you.

I am trying to add a keyboard shortcut to an existing standard Menu Bar Button such as "Tile Window to Left of Screen".
I've tried the different .command modifiers but could not find a way to get access to the existing ones in order to add a keyboard shortcut.
Thanks for your help in advance

Crash seems to be in a private Apple framework. There's some other reports of this floating around but no solutions so far. Any ideas?

Hello all, I'm porting my existing app to catalyst with optimized for mac option. However, I noticed the app will sometimes restore previous open windows if I previously kill it in Xcode. However, these restored windows are also just showing the app entry content instead of restoring the previous scene content. Question, is there anyway to disable this restore scene behavior? Thanks!

Okay so I'm getting this log every time I present a UIAlertController:
Mac Catalyst: Presenting view controller <UIAlertController: 0x10f027000> from detached view controller <MyViewController: 0x10d104080> is not supported, and may result in incorrect safe area insets and a corrupt root presentation. Make sure <MyViewController: 0x10d104080> is in the view controller hierarchy before presenting from it. Will become a hard exception in a future release.
A few points:
MyViewController is not detached and the presentation shows just fine.
I specifically check for this before presenting the alert controller like so:
BOOL okayToPresentError = (self.isViewLoaded
&& self.view.window != nil);
if (okayToPresentError)
{
[self presentErrorInAlertController:error];
}
else
{
//Wait until view did appear.
self.errorToPresentInViewDidAppear = error;
}
It spews out every time an error is fed back to my app and I present the alert controller (I can turn off the network connection and I show an alert controller with a "retry" button in it which will loop the error back so I can replay the error alert presentation over and over again) .
Every time the alert controller is presented, I get this spewing in the console. Please don't start throwing hard exceptions because the check is faulty.

I have a button in my iOS app that opens the Settings app to my app's Notification permissions section. I use UIApplicationOpenSettingsURLString for this (or UIApplicationOpenNotificationSettingsURLString on iOS 15.4 and later). On Catalyst, both of these simply open the settings screen that is auto-generated from the Settings bundle.
How do I get it to open to the appropriate place in System Settings?

List items do not appear to be moveable when they are contained within a popover on Mac Catalyst running on macOS Sonoma. Dragging and dropping a list item simply returns it to its original location, and onMove(preform:) is not called. The same happens using the drag handles with an EditButton() or .environment(\.editMode, .constant(.active)).
Below is a reproducible sample which, to my knowledge, worked as expected on Ventura. It also currently works as expected on iPad. Changing the popover to a sheet makes it work on Mac Catalyst, but then, the view takes up a lot of unnecessary space.
Does anyone have any good workarounds for this issue?
struct ContentView: View {
@State private var isShowingPopover = false
@State private var items = ["one", "two", "three"]
var body: some View {
Button("Show Popover") {
isShowingPopover = true
}
.popover(isPresented: $isShowingPopover) {
List {
ForEach(items, id: \.self) { item in
Text(item)
}
.onMove { fromOffsets, toOffset in
items.move(fromOffsets: fromOffsets, toOffset: toOffset)
}
}
.frame(minWidth: 300, minHeight: 270)
}
}
}
