Is there a way to programmatically launch a macOS Action Extension (related documentation: https://developer.apple.com/library/archive/documentation/General/Conceptual/ExtensibilityPG/Action.html) I'm aware how to create "Action Extensions" but they only seem to be activated from NSTextView "rollover" button. Say I know there is an action extension that works on a particular type of data can I launch it from my app? Obviously we can launch "regular" apps with NSWorkspace by bundle iD but I was wondering if there is any API where my app could directly launch an action extension as the "host app" programmatically.

I see the -resumeAllMediaPlayback: says the replacement method is -setAllMediaPlaybackSuspended:completionHandler: I don't believe suspending and resuming media playback are matching actions, which would mean -resumeAllMediaPlayback: doesn't have a replacement API? The deprecated -resumeAllMediaPlayback: method doesn't seem to work on Sonoma (pauseAllMediaPlaybackWithCompletionHandler: does work but resume does not).

I'm trying to enable the web inspector on WKWebView in a Mac Catalyst app. I'm only doing this for debugging purposes. In the released the web inspector will not be enabled. Doing this under Mac Catalyst does not work:  WKPreferences *prefs = [[WKPreferences alloc]init];   [prefs _setDeveloperExtrasEnabled:YES]; //Assign the WKPreferences to a WKWebViewConfiguration and create the web view.. Is there any way to do this? Thanks in advance.

In Xcode 15 Live Previews are available for UIKit view controllers and views. However I noticed they do not work if the deployment target is < 17.0. If I try to make a live preview for a view controller like so: #Preview { let someVC = ViewController() return someVC } It doesn't load. The error is described below: == PREVIEW UPDATE ERROR: CompileDylibError: Failed to build ASwiftViewController.swift Compiling failed: module 'SwiftUI' has no member named 'VStack' If I raise the deployment target to iOS 17 it starts working.

I have a customizable NSToolbar (using in a Mac Catalyst app "optimized for Mac"). When I right click and choose "Customize toolbar" I get the following error: Conflicting constraints detected: ( "<NSLayoutConstraint:0x6000014a24e0 NSToolbarItemGroupView:0x13de568c0.width <= 88.5 (active)>", "<NSAutoresizingMaskLayoutConstraint:0x6000014f5f90 h=--& v=--& NSToolbarItemGroupView:0x13de568c0.width == 89 (active)>" ).

So I'm looking inside the documentation for TipKit, which ~1400 lines in a single file of documentation. If I right click a symbol there is no "Jump to Definition" in the context menu. Steps to reproduce: Navigate to TipKit generated "header". Right click a symbol like Tip (highlighted in bold): public struct AnyTip : Tip 3rd step) No Jump to Definition menu item appears in the context menu. Is this intentional behavior?

So experimenting with UISplitViewController on Mac Catalyst. I have a triple split. The primary view controller is a sidebar. I have the default sidebar button showing in the toolbar and that collapsed/expands the sidebar fine. But when I drag to try to collapse the split (as is typical on macOS) the sidebar doesn't collapse. It clamps to the min. size. Is there anyway to enable this? I tried passing 0 to -setMinimumPrimaryColumnWidth: but that didn't work.

I was wondering if there is a way to programmatically invoke a Finder "quick action" from a Mac app? I know "old school" services can be invoked using NSPerformService and was looking to do something similar with a quick action. Thanks in advance.

Shortly after presenting a UIDocumentPickerViewController on Mac Catalyst the system throws this exception and I keep hitting my exception breakpoint: NSView: valueForUndefinedKey this class is not key value coding-compliant for the key cell. Appears to be related to the system using Touch Bar APIs (my app isn't currently using Touch Bar APIs directly but the NSOpenPanel created by UIDocumentPickerViewController is). #2 0x0000000198de2828 in -[NSObject(NSKeyValueCoding) valueForUndefinedKey:] () #3 0x000000019884ef3c in -[NSObject(NSKeyValueCoding) valueForKey:] () #4 0x0000000200b75a68 in -[NSObject(UIAccessibilitySafeCategory) __axValueForKey:] () #5 0x0000000200b75960 in __57-[NSObject(UIAccessibilitySafeCategory) safeValueForKey:]_block_invoke () #6 0x0000000200b75f9c in -[NSObject(UIAccessibilitySafeCategory) _accessibilityPerformSafeValueKeyBlock:withKey:onClass:] () #7 0x0000000200b754d0 in -[NSObject(UIAccessibilitySafeCategory) safeValueForKey:] () #8 0x0000000222206b60 in -[NSTouchBarItemAccessibility__UIKit__AppKit _accessibilityPopulateAccessibiltiyInfoFromUIKit] () #9 0x0000000222206b1c in -[NSTouchBarItemAccessibility__UIKit__AppKit _itemViewMinSize:maxSize:preferredSize:stretchesContent:] () #10 0x000000019b3f70bc in -[NSCompressionGroupLayout item:minSize:maxSize:preferredSize:] () #11 0x000000019aff24f4 in -[NSTouchBarItemContainerView _updateMeasuredSizes] () #12 0x000000019aff2358 in -[NSTouchBarItemContainerView minSize] () #13 0x000000019accae98 in -[NSTouchBarLayout _aggregateWidthOfItems:sharesLeftEdge:sharesRightEdge:widthMeasurement:] () #14 0x000000019accb22c in -[NSTouchBarLayout _attributesOfItems:centerItems:givenSize:sharesLeftEdge:sharesRightEdge:xOrigin:] () #15 0x000000019acca930 in -[NSTouchBarLayout attributesOfItems:centerItems:givenSize:] () #16 0x000000019b52bbb0 in -[NSTouchBarView _positionSubviews] () #17 0x000000019b52ba6c in -[NSTouchBarView layout] () -- The exception does get caught (my app doesn't crash) but I hit the exception breakpoint over and over again while the NSOpenPanel is on screen which is annoying.

I have a Mac Catalyst app configured like so: The root view controller on the window is a tripe split UISplitViewController. The secondary view controller in the Split View controller is a view controller that uses WKWebView. Load a website in the WKWebview that has a video. Expand the video to “Full screen” (on Mac Catalyst this is only “Full window” because the window does not enter full screen like AppKit apps do). The NSToolbar overlaps the “Full screen video.” On a triple Split View controller only the portions of the toolbar in the secondary and supplementary columns show through (the video actually covers the toolbar area in the “primary” column). The expected results: -For the video to cover the entire window including the NSToolbar. Actual results: The NSToolbar draw on top of the video. -- Anyone know of a workaround? I filed FB13229032

I'm using WKWebView in a Mac Catalyst app (not sure if using Catalyst makes a difference but it seems WKWebView doesn't get the "full" Mac version AppKit apps do so maybe it does). When a website has a video playing and if I click the button that I guess is a Picture in Picture button next to the "close" button the web kit process gets an unrecognized selector sent to instance exception. -[WebAVPlayerLayer startRedirectingVideoToLayer:forMode: <-- Unrecognized selector. In debugging mode at least my app doesn't crash the video continues to play and the WKWebview is unresponsive to user interaction. I have to force quit my app. -- I'm on Sonoma 14.0

Been testing all day and receipt loading has been working (testing in sandbox) on Mac Catalyst. I'm using StoreKit1. All of a sudden I'm getting the following error when refreshing a receipt: ** Error Domain=AMSErrorDomain Code=203 "Bag Load Failed Unable to retrieve app-receipt-create because we failed to load the bag." UserInfo={NSDebugDescription=Bag Load Failed Unable to retrieve app-receipt-create because we failed to load the bag.** Sandbox server down?

New in iOS 17 is NSCollectionLayoutDimension uniformAcrossSiblingsWithEstimate: method. I have two collection view items positioned side by side in a a grid and would like to use this feature to give them equal heights. I configure the items like so: -Each "box" in grid is made up of two vertical items -Title item configured with a fractional width of 0.5 and a estimated height. -Description item configured with a fractional width of 0.5 and a estimated height. Then the "box" wraps both the "title item" and a description item vertically NSCollectionLayoutSize *boxSize = [NSCollectionLayoutSize sizeWithFractionalWidth:0.5 estHeightUniformAcrossSiblings:estTitleHeight+estDescriptionheight]]; NSCollectionLayoutGroup *boxGroup = [NSCollectionLayoutGroup verticalGroupWithLayoutSize:boxSize subitems:@[titleItem,descriptionItem]]; //Repeat the box twice to make a side by side grid. //entireRowSize is fractional width of 1.0 and estimated height (not uniform across siblings). NSCollectionLayoutGroup *sideBySideGroup = [NSCollectionLayoutGroup horizontalGroupWithLayoutSize:entireRowSize repeatingSubitem:boxGroup count:2]; But at runtime the grids do not have equal heights. It looks exactly the same as it was on iOS 16. Am I doing something wrong? Thanks in advance.

I have a UIViewController subclass I'm using in Mac Catalyst. This view controller is only ever presented as a sheet. When I try to make a live preview for it the preview is displayed a gigantic size (not the sheet's actual size at runtime). I made a separate thread about this: https://developer.apple.com/forums/thread/738641 In order to be able to preview the view controller for Mac Catalyst at the desired size I figured I'd present it on another view controller. #Preview { let wrapperVC = WrapperViewController() return wrapperVC } //In WrapperViewController override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) if (firstViewDidAppear) { firstViewDidAppear = false view.backgroundColor = UIColor.yellow let realVC = ActualVCIWantToPreview() realVC.modalPresentationStyle = .formSheet present(realVC, animated: false); } } But that's not working. However if I change the device from Mac to iPad it does work so it appears modal presentations aren't working for Live Previews on Mac Catalyst (unless I'm doing something wrong but Xcode is reporting no errors it just isn't showing my presented view controller).

I have a Mac Catalyst app. When using "Live Previews" in Xcode 15 for a view controller of mine the live preview renders at a gigantic size in the Preview. This view controller is only ever presented as a "sheet" on Mac at a fixed size so ideally I'd like to be able to specify the "window size" for the preview environment. Is there a way to do this? Thanks in advance.
