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)?

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?

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

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?

With Mac Catalyst, in Big Sur and Monterey, you could use UICommandTagShare as the property list for a UICommand in combination with activityItemsConfiguration and itemProvidersForActivityItemsConfiguration to allow a "Share" submenu to appear in a menu in your app (for instance, under the File menu like many other apps). Starting in Ventura, this submenu no longer appears with that same code, and instead the UICommandTagShare command in the menu now just displays "Share" with no submenu, which triggers a UIActivityViewController to appear in the main window. Is there any way to still allow a Share submenu to work in Ventura and beyond with Mac Catalyst? Thanks so much for any help!

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(_:).

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) } } }

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!

Can not select anything within WkWebView editor view of my MacCatalyst app when running on macOS 14 Sonoma. Any selection gesture or command key fails to select anything in content editable WKWebView, so none of the Editor tools can be activated. My application uses the nnhubbard / ZSSRichTextEditor WKWebView-based Rich Text Editor: https://github.com/nnhubbard/ZSSRichTextEditor. The app is built with Xcode 15.0 or 15.0.1. The app is a Catalyst app that implements an editor view with a ZSSRichTextEditor WKWebView. The problem does not occur if the the app is run in iOS or macOS 11, 12, or 13 (Catalina, Monterey, or Ventura.) The issue only occurs in macOS 14 Sonoma.

It appears that we are not able to reorder rows in our tables when running our iOS/iPadOS app under Mac Catalyst. It appears that all the delegate methods are returning true indicating the row can be moved and edited. The reordering handles appear in editing move and the row can be moved around (also using drag and drop) but the user interface is not indicating that the row can be dropped to be reordered. It's as if the proposed destination path is being rejected. I tried setting up that delegate method (thinking that maybe the default for that is messed up on Mac Catalyst) but it had no effect. Every table in our system performs this way. Here is a link to an example video that shows the table view not working: https://onsongapp.s3.amazonaws.com/Reordering%20Example.mp4 Please advise if there is something else that needs to be implemented or changed for Mac Catalyst to properly handle table cell reordering.

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!

This is verified to be a framework bug (occurs on Mac Catalyst but not iOS or iPadOS), and it seems the culprit is AVVideoCompositionCoreAnimationTool? /// Exports a video with the target animating. func exportVideo() { let destinationURL = createExportFileURL(from: Date()) guard let videoURL = Bundle.main.url(forResource: "black_video", withExtension: "mp4") else { delegate?.exporterDidFailExporting(exporter: self) print("Can't find video") return } // Initialize the video asset let asset = AVURLAsset(url: videoURL, options: [AVURLAssetPreferPreciseDurationAndTimingKey: true]) guard let assetVideoTrack: AVAssetTrack = asset.tracks(withMediaType: AVMediaType.video).first, let assetAudioTrack: AVAssetTrack = asset.tracks(withMediaType: AVMediaType.audio).first else { return } let composition = AVMutableComposition() guard let videoCompTrack = composition.addMutableTrack(withMediaType: AVMediaType.video, preferredTrackID: Int32(kCMPersistentTrackID_Invalid)), let audioCompTrack = composition.addMutableTrack(withMediaType: AVMediaType.audio, preferredTrackID: Int32(kCMPersistentTrackID_Invalid)) else { return } videoCompTrack.preferredTransform = assetVideoTrack.preferredTransform // Get the duration let videoDuration = asset.duration.seconds // Get the video rect let videoSize = assetVideoTrack.naturalSize.applying(assetVideoTrack.preferredTransform) let videoRect = CGRect(origin: .zero, size: videoSize) // Initialize the target layers and animations animationLayers = TargetView.initTargetViewAndAnimations(atPoint: CGPoint(x: videoRect.midX, y: videoRect.midY), atSecondsIntoVideo: 2, videoRect: videoRect) // Set the playback speed let duration = CMTime(seconds: videoDuration, preferredTimescale: CMTimeScale(600)) let appliedRange = CMTimeRange(start: .zero, end: duration) videoCompTrack.scaleTimeRange(appliedRange, toDuration: duration) audioCompTrack.scaleTimeRange(appliedRange, toDuration: duration) // Create the video layer. let videolayer = CALayer() videolayer.frame = CGRect(origin: .zero, size: videoSize) // Create the parent layer. let parentlayer = CALayer() parentlayer.frame = CGRect(origin: .zero, size: videoSize) parentlayer.addSublayer(videolayer) let times = timesForEvent(startTime: 0.1, endTime: duration.seconds - 0.01) let timeRangeForCurrentSlice = times.timeRange // Insert the relevant video track segment do { try videoCompTrack.insertTimeRange(timeRangeForCurrentSlice, of: assetVideoTrack, at: .zero) try audioCompTrack.insertTimeRange(timeRangeForCurrentSlice, of: assetAudioTrack, at: .zero) } catch let compError { print("TrimVideo: error during composition: \(compError)") delegate?.exporterDidFailExporting(exporter: self) return } // Add all the non-nil animation layers to be exported. for layer in animationLayers.compactMap({ $0 }) { parentlayer.addSublayer(layer) } // Configure the layer composition. let layerComposition = AVMutableVideoComposition() layerComposition.frameDuration = CMTimeMake(value: 1, timescale: 30) layerComposition.renderSize = videoSize layerComposition.animationTool = AVVideoCompositionCoreAnimationTool( postProcessingAsVideoLayer: videolayer, in: parentlayer) let instructions = initVideoCompositionInstructions( videoCompositionTrack: videoCompTrack, assetVideoTrack: assetVideoTrack) layerComposition.instructions = instructions // Creates the export session and exports the video asynchronously. guard let exportSession = initExportSession( composition: composition, destinationURL: destinationURL, layerComposition: layerComposition) else { delegate?.exporterDidFailExporting(exporter: self) return } // Execute the exporting exportSession.exportAsynchronously(completionHandler: { if let error = exportSession.error { print("Export error: \(error), \(error.localizedDescription)") } self.delegate?.exporterDidFinishExporting(exporter: self, with: destinationURL) }) } Not sure how to implement a custom compositor that performs the same animations as this reproducible case: class AnimationCreator: NSObject { // MARK: - Target Animations /// Creates the target animations. static func addAnimationsToTargetView(_ targetView: TargetView, startTime: Double) { // Add the appearance animation AnimationCreator.addAppearanceAnimation(on: targetView, defaultBeginTime: AVCoreAnimationBeginTimeAtZero, startTime: startTime) // Add the pulse animation.

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.
