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

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

Anyone knows about any workarounds for this crash "Spatial presentations are not permitted from popovers."

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

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!

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) } } }

Is there a way to link a prebuilt dylib that was built for the 'macOS' platform on Mac Catalyst without being warned by Xcode? Generally it would be better to just recompile for Mac Catalyst but this is a third party library and they have a complicated build system with dozens of dependencies that doesn't support Mac Catalyst as of now (although they have iOS and Mac 'regular'). So I would have to spend quite a bit of time trying to sort through their build system to make a Catalyst version myself. The library uses no platform specific UI code and I'm fairly certain that macOS build would work just fine on Mac Catalyst without any changes since it isn't UI related at all. It seems to work fine (apart from Xcode warning me about linking a .dylib built for macOS on Mac Catalyst). I could shim all this away in a NSBundle that is aware of the AppKit world but then I have to make all method calls to the third party framework on Mac Catalyst through the bundle and it would separate my iOS and Catalyst code relying on the same implementation which isn't great. Is there a way I could just replace the 'macOS' platform in the .dylib with macCatalyst to get rid of the warning?

Hello, is there a recommended way to render Menu items, e.g in a SwiftUI ContextMenu with icon (SFSymbols)? Let's say I have the following setup: Both buttons render fine on native macOS (e.g Sonoma) but Catalyst refuses to render the symbol at all. I tried every possible combination I could think off. The only way I found was to directly copy and paste a symbol from the SF symbols app and inline it with the label string as unicode. Unfortunately I have a couple custom SF symbols so this isn't really an option for me. I feel like this is a perfectly valid usecase, as it makes the menu visually a lot easier scannable. With UIKit and Ventura this at least worked for Menubar items but now also seems broken on Sonoma. I would greatly appreciate any hints. Thanks!

I have a multiple window Mac Catalyst app. I'm using a NSToolbar and the menu bar via UIMenuBuilder. I noticed after changing windows the menu bar isn't always validating properly. For example my app implements "Undo" and "redo". So I can reproduce the issue using these steps: Perform an action that can be undone. Open a new window. This new window has its own undo manager. In the Menu bar select Edit -> Undo Undo validates even though the current window has nothing on its local undo stack. If invoked undo is performed on the inactive window which definitely seems wrong. The same thing sometimes happens in reverse (that is, undo doesn't validate when it should after switching windows). This also happens with other actions after switching windows. Sometimes I can get the actions to validate by hitting the Tab key to move focus then shift tabbing back, which seems to force proper lookup in the responder chain (but sometimes that doesn't work). It seems that Catalyst is losing track of the real active window/window scene for some reason and is validating actions on the wrong window scene. Anyone experience this and know where I could be going wrong and/or know of a possible workaround? I tried subclassing UIApplication and implementing the methods there (and then forwarding them to the active UIWindowScene). However this doesn't work, the wrong window scene has its activationState set to UISceneActivationStateForegroundActive when the problem occurs.

Is anyone else running into an issue with navigation bar titles in Catalyst app being shown higher up than normal when presented as a modal sheet under Sonoma (see screenshot)? I tried adjusting the titlePositionAdjustment for the appearance, but this only affects the title and not any buttons that may be in the navigation bar, making them uneven. Any suggestions would be helpful as I'm at my wits end on this one.

If I do this, I'll only have to submit the iOS version of the app and not have to dork with two app reviews. What do you think? What am I missing?

I have a Mac Catalyst App that I switched over to the SwiftUI lifecycle. I am trying to add MenuBarExtra to the app : if #available(macOS 13.0, *) { MenuBarExtra("....", systemImage: ......) { .......... } } However, I get an error : 'init(_:systemImage:content:)' is unavailable in iOS 'MenuBarExtra' is unavailable in iOS How do I add MenuBarExtra to the app?

I have looked high and low all and cannot find an answer or solution. I have an app that is primarily used by Mac users. I am looking to implement promo codes in the coming weeks. The presentCodeRedemptionSheet call does not work for Mac Catalyst apps saying "This function doesn’t affect Mac apps built with Mac Catalyst" in the documentation. AppStore.presentOfferCodeRedeemSheet also does not work for Mac Catalyst. If it is the case that you can't redeem in-app, that is fine if I can direct users to the Mac App Store to redeem promo codes, but I cannot find a way to do that either. I can only find a route to redeem gift cards. I have also tried clicking on a specific promo code link (something like https://apps.apple.com/redeem?ctx=offercodes&id=00000000&code=PROMOCODE) and that just redirects to the Gift Card redemption screen in the Mac App Store. So is there any way for a Mac only user (a user that does not have an iPhone or iPad) to use app promo codes? Thanks!

I have a Swift Package Build Tool Plugin to generate localizations and design tokens, which looks like this currently. // Copyright © 2023 MEGA Limited. All rights reserved. import PackagePlugin @main struct GenerateTokenBuildTool: BuildToolPlugin { func createBuildCommands(context: PluginContext, target: Target) async throws -> [Command] { guard let target = target as? SourceModuleTarget else { return [] } return try target.sourceFiles(withSuffix: "xcassets").map { assetCatalog in let base = assetCatalog.path.stem let input = assetCatalog.path let output = context.pluginWorkDirectory.appending(["\(base).swift"]) // Use this when archiving for MacCatalyst let tool = try context.tool(named: "AssetTokenGenerator").path let toolName = tool.lastComponent let path = tool.removingLastComponent() let macPath = path.removingLastComponent().appending(subpath: path.lastComponent + "-maccatalyst") let executable = macPath.appending(subpath: toolName) // // Use this when archiving for iOS/iPadOS // let executable = try context.tool(named: "AssetTokenGenerator").path return .buildCommand( displayName: "Generating tokens for \(base).xcassets", executable: executable, arguments: [input.string, output.string], inputFiles: [input], outputFiles: [output] ) } } } If you notice, I need to do a bit of manual bug fixing when determining the path of my executable. When building for Mac Catalyst, context.tool(named:).path is pointing to an incorrect folder, thus failing the build for my project with this error: Command PhaseScriptExecution failed with a nonzero exit code sandbox-exec: execvp() of '//Users/mega-jfe/Library/Developer/Xcode/DerivedData/MEGAVPN-efdcwfcaosxfvneqjuvhrvdmbkax/Build/Products/Debug/AssetTokenGenerator' failed: No such file or directory It's suppposed to be using the Debug-maccatalyst folder, but Xcode is pointing the path to Debug. I feel like this is a bug, or else please let me know how I can handle this so that I can build for both without manually changing the code when building for Catalyst. Thanks!
