Uploading an App Preview Video for a Mac App Fails with Error "Your app preview contains unsupported or corrupted audio" even though the video contains no audio. Anyone run into this and know of a workaround? I filed FB12151982

The man page of copyfile sates the following: COPYFILE_CLONE [..] Note also that there is no support for cloning directories" COPYFILE_CLONE_FORCE [...] Note also that there is no support for cloning directories: if a directory is provided as the source, an error will be returned. Now the man page for clonefile: > Cloning directories with these functions is strongly discouraged. Use copyfile(3) to clone directories instead. -- So am I to enumerate the content of a directory build subfolders along the way in the target destination and clone each file inside individually? If I recall NSFileManager seems to clone a large directory instantly (edit actually I remembered wrong NSFileManager does not do this. Finder seems to copy instead of clone as well). On further inspection, clonefile states that it can do this, but it is discouraged. Interesting. I wonder why. If src names a directory, the directory hierarchy is cloned as if each item was cloned individually. However, the use of clonefile(2) to clone directory hierarchies is strongly discouraged. Use copyfile(3) instead for copying directories. P.S. - Forgive me if I posting this in the wrong category, I couldn't find a "category" in the list of available categories on these forums that seems appropriate for this question.

I'm trying to create a dynamic menu on Mac Catalyst. Using a UIBarButtonitem like so to make a "pull down" button: UIDeferredMenuElement *deferredmenuElement; deferredmenuElement = [UIDeferredMenuElement elementWithUncachedProvider:^(void (^ _Nonnull completion)(NSArray<UIMenuElement *> * _Nonnull)) { UIAction *actionOne = [UIAction actionWithTitle:@"Action One" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action one fired."); }]; UIAction *actionTwo = [UIAction actionWithTitle:@"Action Two" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action two fired."); }]; UIAction *actionThree = [UIAction actionWithTitle:@"Action Three" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action three fired."); }]; completion(@[actionOne,actionTwo,actionThree]); }]; UIMenu *wrappedMenu = [UIMenu menuWithChildren:@[deferredmenuElement]]; UIBarButtonItem *uiBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:nil menu:wrappedMenu]; uiBarButtonItem.image = [UIImage systemImageNamed:@"rectangle.and.pencil.and.ellipsis"]; self.navigationItem.rightBarButtonItems = @[uiBarButtonItem]; The button appears in the toolbar but when I click it to expose the menu I get a menu with on element in it that says "Loading...". The the uncached provider block is never called. Running Ventura 13.2.1 and Xcode 14.2.

In a SwiftUI source file Xcode displays a window with a Split View. The first split is the source code and the second split is the preview. My question is, is there a way for me to have the preview take over the entire window width (I want to collapse the source code pane and just look at the preview)? I can easily collapse the Preview pane by dragging the split to the right to collapse (but it doesn't work in reverse). I also can toggle the preview pane by going to Editor -> Canvas in the Menu bar. Currently I'm using SwiftUI just to get a live preview of UIKit view controllers so I'm not interested in looking at the SwiftUI source code, though I imagine displaying a full window preview in a separate window would be useful for SwiftUI developers too. You could edit the source code on one monitor and have the preview window on an external display. Is this not possible?

I'm using compositional layout with UICollectionView. In a particular section I configure the compositional layout to use an estimated height because I want self sizing items determined by Autolayout Constraints. Now I have a custom content configuration with autolayout constraints. At runtime I hit this log about conflicting constraints: [LayoutConstraints] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) [...] <NSLayoutConstraint:0x6000024af160 UIImageView:0x120745520.height == 130 (active)> <NSLayoutConstraint:0x6000024af2a0 MyCustomContentView :0x120748d60.height >= 1.04839*UIImageView:0x120745520.height (active)> <NSLayoutConstraint:0x6000024b08c0 'UIView-Encapsulated-Layout-Height' UICollectionViewListCell:0x1214392f0.height == 44 (active)> Will attempt to recover by breaking constraint <NSLayoutConstraint:0x6000024af160 UIImageView:0x120745520.height == 130 (active)> The "UIView-Encapsulated-Layout-Height" on UICollectionViewListCell with a value of 44.0 appears to be a constraint created by the system. I'm not sure why a hard coded height of 44.0 is being used when the compositional layout is returning a section that only uses estimated heights (created via NSCollectionLayoutDimension estimatedDimension). Any ideas how I can avoid this? I'm not using custom UICollectionView cells but I am using a custom content configuration and a custom content view and setting my content configuration on a UICollectionViewListCell.

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'm looking for the AVAudioEngine in Practice video from WWDC 2014 (session 502) but can't seem to find it anywhere. Does anyone have a link to this session video? I can only find the slides. Thanks.

The documentation for NSURL -URLByAppendingPathComponent: states: "Returns a new URL by appending a path component to the original URL." Path component is singular. But this "works" : NSURL *testURL = [applicationsDirectory URLByAppendingPathComponent:@"Evil/../../" isDirectory:YES]; So my questions are: One) Was it always this way? I can't recall if it was like this before the Foundation rewrite and I just never stumbled across? and Two) Is it intended behavior? The API seems to suggest that you append one path component on the url with this method. But I guess you can append as many as you want?

So I tried installing this update three times. Each time all 7.6 GB "downloads" and begins the "Installing..." shortly after Xcode starts "Installing" I get a notification in the Notification Center "Unable to Download App" "Xcode could not be installed please try again later."...Anyone else?

I now have an M1 Mac and an Intel Mac. I have an XCFramework that targets the iOS simulator and devices. My XCFramework works fine but I'd like to be able to run my app (which uses the XCFramework) on the iOS simulator on both my Macs (m1 &amp; intel). Now my M1 Mac complains about the x86_64 architecture when I try to run it on the simulator. So I rebuilt the XCFramework (recompiling the simulator version on the M1 Mac). I'm compiling the source code from Terminal (building OpenSSL). There is no .xcarchive here. Anyway now the app runs on the simulator on the M1 Mac but on the Intel Mac it won't build (basically the same problem in reverse). So... I made three versions of the library now (for iOS devices, iOS simulator on m1 Mac, and for the iOS simulator on Intel Macs). When I try to make an XCFramework to wrap all three static libraries I get the following error: Both "ios-x86_64-simulator" and "ios-arm64-simulator" represent two equivalent library definitions. I found another thread where the accepted answer was to lipo the x86_64 and arm simulators together, then build the xcframework. I've seen posts from Apple engineers that say using lipo is not supported (reference: https://developer.apple.com/forums/thread/709812?answerId=719667022#719667022 ) So where am I going wrong? I try to make the xcframework like so: xcodebuild -create-xcframework -library build/sim/openssl-1.1.1q/libcrypto.a -headers build/sim/openssl-1.1.1q/crypto -library build/phones/openssl-1.1.1q/libcrypto.a -headers build/phones/openssl-1.1.1q/crypto -library build/intelsim/openssl-1.1.1q/libcrypto.a -headers build/intelsim/openssl-1.1.1q/crypto -output build/Crypto.xcframework

I know WKWebview is in another process from the main app. My question is is the UIBackgroundModes audio entry in Info.plist required on the main app for WKWebview to play audio/video/airplay in the background? Or is simply setting WKWebViewConfiguration allowsAirPlayForMediaPlayback and allowsPictureInPictureMediaPlayback enough? I recall having issues with background audio from WKWebView on older versions of iOS a couple years ago so I added the audio entry to the Info.plist.... but I just removed the key from the Info.plist and background audio from WKWebview seems to be working fine...maybe audio background mode is not required? Or does it only seem to be working because my app is attached to the debugger? Or is this a bug?

I'm using UIDocumentPickerViewController to open a url. Works fine in debug mode but version on the App Store is failing. Code to create the document picker is like: NSArray *theTypes = [UTType typesWithTag:@"docxtensionhere" tagClass:UTTagClassFilenameExtension conformingToType:nil]; UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc]initForOpeningContentTypes:theTypes]; documentPicker.delegate = self;   [self presentViewController:documentPicker animated:YES completion:nil]; So in debug mode this is all gravy. -documentPicker:didPickDocumentsAtURLs: passes back a URL and I can read the file. In release mode I get a URL but my app is denied access to read the file. After inspecting some logging it appears the sandbox is not granting my app permission. error Domain=NSCocoaErrorDomain Code=257 "The file “Filename.fileextensionhere” couldn’t be opened because you don’t have permission to view it." UserInfo={NSFilePath=/private/var/mobile/Library/Mobile Documents/comappleCloudDocs/Filename.fileextensionhere, NSUnderlyingError=0x2834c9da0 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}} -- If I'm doing something wrong with UIDocumentPickerViewController it is a real shame that permission is not being denied in Debug mode, as devs are more likely to catch in prior to release. Anyone know where I'm going wrong and if not have a workaround? Thanks in advance.

So I built my app with Mac Catalyst. I see this little line appear and disappear periodically in the window. Then all of a sudden it disappears when the window's activation state changes sometimes. It looks like a weird little glitch. Turns out this is the title bar's separator which is UITitlebarSeparatorStyleAutomatic (I believe the system hides/shows the separator in this mode based on current window states. I change the separator style to shadow and sure enough it draws like a shadow and never disappears. It's not even close to where the separator is supposed to be (nowhere near the title bar). The only workaround I have is to use UITitlebarSeparatorStyleNone which I'll do if I have to but was wondering if someone else has run into this and has a better workaround.

So when a row is selected in UITableView and the table view / cells within it have focus, and the window is active.... the rows are selected with the system Accent color (in my case blue). I have a view inside the table view cell that does custom drawing. When the cell is selected I draw text white (when unselected I draw the text using UIColor.labelColor). So when the window is not active but the table view row is selected, the selected background color changes to light gray. In this case I draw the text black (because it looks better against the light gray selection color on an inactive window). However when the row is selected but another view in the window has focus (say the sidebar) the selected row turns back to the light gray color. In this case my text is incorrectly drawing white instead of black on the light gray background. How do I check for this state from UIKit? In AppKit I think I'd be using: NSColor.unemphasizedSelectedTextColor https://developer.apple.com/documentation/appkit/nscolor/2998834-unemphasizedselectedtextcolor?language=objc I have to update text color manually because I'm doing custom drawing in these table view cells (I have a view that overrides drawRect:) I can't just use the dynamic colors like UIColor.labelColor. I have to set the colors on state change manually and call setNeedsDisplay on my view. How do I check for the unemphasized state? I did inspect whether or not my table view cell is in the active focusItem's environment, and if it is not I assume the light gray selected color is being used. This worked most of the time but there still seems to be some states where the unemphasized selection color (light gray)is being used on selected cells when the the table view cell is in the active focus environment and my text incorrectly draws white.

Is it possible to create a popover in Mac Catalyst that allows you to detach it into a new window like NSPopover? https://developer.apple.com/documentation/appkit/nspopoverdelegate/1534822-detachablewindowforpopover?language=objc Thanks in advance
