In SwiftUI on macOS, you can add items to the main menu by using things like CommandGroup, CommandMenu. But the default menus already have items. For example, the Edit menu has Undo, Redo, Cut, Copy, Paste, Delete, Select All. Those menu items are grayed out and don't do anything. Is there a way to hook some Swift code to these? Or do you just use CommandGroup(replacing: ...) to replace them? That doesn't seem right; why put them there if you just have to replace them? Besides hooking up a function to run when they get clicked, I'd like to know how to enable and disable them depending on app state.         WindowGroup {             MyContentView()         }.commands {             SidebarCommands()             CommandGroup(after: .newItem) {                 Button { newFolder() } label: { Text("New Folder") }                     .keyboardShortcut("n", modifiers: [.command, .option])             }         }

Is there a way to quickly confirm a "fix-it" popup using only the keyobard? The "Fix Next Issue" and "Fix Previous Issue" commands just show the popup. I still have to manually press the "Fix" button. Return key simply dismisses the popup. Clicking that tiny button 1000's of times is annoying. Xcode 12.4. In IntelliJ I can fly through these with a nice keyboard shortcut. I'm looking for a similar thing in Xcode.

Does anyone use this? I can't get it working. I'm talking about code in normal swift files, not playgrounds.Example:///  ///  ///Neither one displays anything in the documentation popover or the Quick Help Inspector.The docs act like it works: https://developer.apple.com/library/archive/documentation/Xcode/Reference/xcode_markup_formatting_ref/Images.html#//apple_ref/doc/uid/TP40016497-CH17-SW1A lot of my code would really benefit from diagrams in documentation. I'd love to be able to use this.

I've added an NSTrackingArea to my NSView because I want a certain rectangular area to show a different cursor. As expected, my view gets a call to it's cursorUpdate:(NSEvent*) method, but how do I tell whether it's an "enter" or "leave". - (void)cursorUpdate:(NSEvent *)event { // Do I push or pop my custom NSCursor? } I notice the event.modifierFlags changes from 8 to 9. But I don't see any public enum constants to test that, so I don't know if I can depend on that. The public enum contains stuff like this, in the higher bits. typedef NS_OPTIONS(NSUInteger, NSEventModifierFlags) { NSEventModifierFlagCapsLock = 1 << 16, NSEventModifierFlagShift = 1 << 17, ... The tracking area setup code: NSRect nsRect = ... NSTrackingAreaOptions options = NSTrackingCursorUpdate | NSTrackingActiveInKeyWindow; NSTrackingArea *trackingArea = [[NSTrackingArea alloc] initWithRect: nsRect options: options owner: owner userInfo: userInfo]; [myView addTrackingArea: trackingArea];

I have an app that plays synthesized speech. If I call the AVSpeechSynthesizer speakUtterance method with a premium voice, then no noise comes out, and the synth never works again. However, if I first use a non-premium voice, it works, and I can then call it with premium voices and they speak too.

Hi,I need to save and load metal textures to a file. Example code below is below. I'm noticing the RGB values are changing as it gets saved and reloaded again.metal texture pixel: RGBA: 42,79,12,95after save and reload: 66,88,37,95I thought it might be a colorspace issue, but the colorspaces I’ve tried all had the same problem. `genericRGBLinear` got close, but there’s got to be a way to save the RGB data and get it back exactly. ?thanks,RobCode:// saving... let ciCtx = CIContext() let ciImage = CIImage(mtlTexture: metalTexture, options: [:]) [ … transfrom to flip y-coordinate …] let colorSpace = CGColorSpaceCreateDeviceRGB() let cgImage = ciCtx.createCGImage(ciImage, from: fullRect, format: kCIFormatRGBA8, colorSpace: colorSpace)! let imageDest = CGImageDestinationCreateWithData(mData, kUTTypePNG, 1, nil)!

I need to get at the files of an app (one that I developed). It's sitting there on the home screen of my iPad, and I can run it. But in the "Devices and Simulators" window in Xcode, in the "Installed Apps" list, it's not there. That list is how I would normally get the "container" so I can see the files. Why would an app that is obviously on the device not be in the list? Is there another way to get the container/files?

I have a button to restore purchases in my app. It calls AppStore.sync() as suggested by sample code. I'm testing in the sandbox, I put my device in airplane mode, and it throws StoreKitError.userCancelled. That's odd. Anyone else see this? I'd like to show an error alert popup to the user here, but I can't differentiate between this an a real userCancelled.

I can't find any documentation on this. I've tried adding png files to my project and adding them with the "+" button here, but Xcode just ignores me. No error message. Is it looking for a specific file format? This is Xcode 13.

I created a simple app in Xcode. Installed and ran it in the iOS Simulator. I can also start it from command line like this: % xcrun simctl launch booted com.example.TestBuildCommands --console com.example.TestBuildCommands: 52877 % It just prints that one line and returns my shell prompt. But the help for launch says that --console should: "Block and print the application's stdout and stderr to the current terminal." In my main() function I have: int main(int argc, char * argv[]) { printf("In main.\n"); ... Shouldn't I be seeing that message in my terminal screen? % xcrun simctl help launch Launch an application by identifier on a device. Usage: simctl launch [-w | --wait-for-debugger] [--console|--console-pty] [--stdout=<path>] [--stderr=<path>] [--terminate-running-process] <device> <app bundle identifier> [<argv 1> <argv 2> ... <argv n>] --console Block and print the application's stdout and stderr to the current terminal. Signals received by simctl are passed through to the application. (Cannot be combined with --stdout or --stderr) [...] ps. Anyone know how to turn off syntax highlighting in those triple-backquoted code blocks that are meant to be just terminal text, not highlighted code?

Hi, If I change the AppIcon in Xcode's Assets.xcassets, and rerun my app, the image used in the dock and app switcher does not update. If I "Clean Build Folder", and re-run, then it updates. This is annoying when I keep tweaking the colors in the icon and want to see how they look. A full rebuild takes a while, because I have a few Swift Package dependencies. Anyone know a trick to get the AppIcon to stop caching (or whatever it's doing)? I tried killall Dock and killall Finder, but that didn't help. (macOS 11.2.3) Rob

When I try to run my app on my iPhone, from Xcode, I get a popup that says Unable to Install "AppName". There is some text in the popup. Here's the first part of it. (I replaced the real app's name with "AppName".) Anyone know how to fix this?

I'm working on a macOS app that I want to give "Full Disk Access". When I run from Xcode, I get "permission denied" errors when reading a file in my home directory. What can I do so that I can run and debug from Xcode? I dragged the binary from the derived data folder to the System Preferences list for Full Disk Access, but that seems to do nothing.

I had the following code in a program that I used to encrypt some important files. I haven't run it in a few years. It used to work, and now it seems the password is mysteriously gone from my Keychain! The return value is now errSecItemNotFound. I'm upset with myself for not backing up the key/password somewhere else. Is there anywhere this could be hiding? Did Apple move it somewhere? I know they created this "Passwords" app in recent years, but I don't see anything in there with the "account" string I used. I run the app from Xcode, so maybe it is in the "container" data somewhere? I do see keychain files under ~/Library. Maybe there is a way to look through old Time Machine backups. Ug. So stressful. Just looking for pointers on where the data might be, and why it might have disappeared. Unfortunately it was not a "guessable" password, it was a generated 256 bit key, base64 encoded. Perhaps I could crack that with brute force if I'm determined enough... public static func queryGenericPasswordAsString(account: String) throws -> String { let query: [String: Any] = [kSecClass as String: kSecClassGenericPassword, kSecMatchLimit as String: kSecMatchLimitOne, kSecAttrAccount as String: account, kSecReturnAttributes as String: true, kSecReturnData as String: true] var item: CFTypeRef? let status = SecItemCopyMatching(query as CFDictionary, &item) guard status != errSecItemNotFound else { throw KeychainError.noPassword } ... }
