I have a very basic macOS bundled application with just the empty delegate methods implemented. I am wanting to launch this application as a daemon but when I am loading my daemon, it fails to run with the error: The application cannot be opened for an unexpected reason, error=Error Domain=NSCocoaErrorDomain Code=257 "The file “GUIDaemon” couldn’t be opened because you don’t have permission to view it."

I am having a bundled application(.app file) and I am wanting to run this application via ssh session which does not have GUI access. Launching this application in a desktop GUI session, runs the application perfectly. However, on running it on the same machine via ssh session produces an error. Note: My application does not bring up any GUI window(it' just produces some logs on the terminal), so running it in a non-GUI environment should have worked. I get the below error when trying to launch the unix exe in the .app bundle( ./Myapp.app/Contents/MacOS/Myapp ) on the terminal. I have observed that applicationDidFinishLaunching(_:) gets called and then the below error occurs. +[NSXPCSharedListener endpointForReply:withListenerName:replyErrorCode:]: an error occurred while attempting to obtain endpoint for listener 'ClientCallsAuxiliary': Connection interrupted I tried running other bundled applications via ssh, but all seems to produce the same error. Can someone confirm Is running bundled application in a non GUI session not allowed by Apple. If its allowed, how can I solve this? Even running the .app file using the open command fails to launch the application, although it produces a different error which is consistent across different applications.

I wanted to perform handling for the exception in my mac and ios application, I am following this link, where it is suggested to follow either the mach exception handling or use Unix signals. I did not find many resources that could be followed to implement mach exception as suggested. Below are the few resources I could find. Can someone point to the some documentation that apple provides for this or some other helpful documentation. https://gist.github.com/rodionovd/01fff61927a665d78ecf

I have an exception handling frame for an Xcode application in macOS, which contains Cpp and Swift code. I am using the Unix signals frame for handling exceptions using sigaction. My sigaction signal handler get invoked when there is a swift or Cpp exception. However for some exceptions like SIGSEGV, the signal handler gets called repeatedly. To handle this I am using the SA_RESETHAND flag so that the handler gets invoked only once, and then the default action for the signal take over to terminate the process. This approach works well when an exception occurs due to Cpp code, however when it occurs due to Swift code, the signal handler still gets invoked repeatedly. Can someone explain why is this happening and What is the solution to this?

I have created an intent using AppIntent and this intent(TWIntent in the code below) can be seen in the shortcuts app as an action to create the shortcut. I am using AppShortcutProvider to create the shortcut so that user can directly make use of it. However, my shortcut does not appear in the shortcut app. The phrases used also do not launch the intent in the spotlight search. Below is my AppShortcutProvider file: @available(macOS 13.0, *) struct TWShortcuts: AppShortcutsProvider { static var appShortcuts: [AppShortcut] { AppShortcut( intent: TWIntent(), phrases: [ "Open Intent in \(.applicationName)", "Open \(.applicationName) Intent", "Open my Intent in \(.applicationName)", "Open my \(.applicationName) Intent", "Open TWIntent" ], shortTitle: "Open TWIntent", systemImageName: "rectangle.stack.fill" ) } static var shortcutTileColor: ShortcutTileColor = .lightBlue } Is there something I m missing? Also can these phrases be used for siri launch in macOS because the documentation mentions that macOS does not have siri capability? Below is my AppIntent file: import SwiftUI @available(macOS 13, *) struct TWIntent: AppIntent { static let title: LocalizedStringResource = "TWIntent" static var description = IntentDescription("try adding this sample action as your TW shortcut") //launch app on running action static var openAppWhenRun: Bool = false static var parameterSummary: some ParameterSummary { Summary("Get information on \(\.$TWType)") } @Parameter(title: "TWType", description: "The type to get information on.") var TWType: String func perform() async throws -> some IntentResult & ReturnsValue<String> & ProvidesDialog { //perform essential task here to update the application content return .result(value: TWType, dialog: "Logged a 15 minute break.\(TWType)") } }

I have macOS application and I want to provide an action for it in the 'Shortcuts' app QuickAction list. I was using InApp handling to present my intent created in the intent.intentdefinition file as action in the shortcuts app and it was working. However, this action perform a very lightweight task so I intent to have the action implemented as an extension in my xcode project. According to my minimum deployment(i.e macOS 11.0) I found that 'Intents Extension' could be used. I have added the 'Intents extension' target to my main application and created an intent using the intent.intentdefinition file. However, my intent does not appear in the shortcuts app. I have verified it multiple time to ensure I am not missing anything, but still the intent is not present in the shortcuts app action. I wanted to be know, Is this even possible? cause this apple documentation only mentions about iOS and watchOS app. It also does not mention If our custom intent(created using Intents extension) in the intents extension can be exposed to the shortcuts app. For macOS 13.0+, I have used the 'AppIntents extension' and I m able to achieve the same. So, I suppose the same should be possible using the 'Intents extension'

I have an executable in macOS that I m launching as a User Agent. The same executable can be launched in multiple ways like either user can directly click the exe to launch it, or user can launch it from the terminal using ./ etc. One similar way is when the user launches the exe as a User Agent(i.e daemon in user session). In this scenarios, I want to identify in my exe If my user has launched it as agent to perform certain task. I wanted to know how can I accurately determine this? I have tried figuring out If there is some unique session that agents operate in, but I could not find anything. Can someone help here? Is this even possible?

I have a bundled application(.app file) in macOS which is a non-interactive application. This app does not link to any GUI frameworks and I am able to launch it using the 'open' command in a normal GUI login session. However, when I perform ssh login to that user and then If I try to launch the application, it fails to launch. I assume that this is happening because my ssh session is a non-GUI session, and 'open' command is due to some reason failing to run in a non-GUI environment, but I m not sure. Can someone help me understand why is this happening?

I have a public swift function with the below declaration : public func InternalMain (_ pNumOfArgs : Int32, _ pCmdlineArgs : UnsafeMutablePointer<UnsafeMutablePointer<Int8>?>) -> Int32 {..} I need this function as public because I need to invoke in from a different library. But the above declaration produces an error in my generated swift header i.e '-swift.h' file because 'UnsafeMutablePointer<UnsafeMutablePointer?>' type cannot be represented in the swift generated header. Can someone help how do I get past this. This is a class independent function and I tried using the '@nonobj' to prevent this from getting in the generated header but it still gives an error.

I have a .app file that I want to run as a daemon. Now there are two ways of running .app as a daemon/agent in macOS. using .app file : I can specify this in the daemon plist as: <key>ProgramArguments</key> <array> <string>/usr/bin/open</string> <string>/Applications/myApp.app</string> </array> using unix exe within .app file <key>ProgramArguments</key> <array> <string>myApp.app/Content/MacOS/MyApp</string> </array> Basically I wanted to know what is the Apple recommendation on how we should be creating daemon plist. For point 2, is it appropriate to use the unix executable within bundle?Will it not cause any issue in the running application? Is will be helpful if there is some apple documentation to support this.

I wanted to create a bundled macOS application that can be run in background. This application should also be capable of running in a non-gui environment. How should I create the application with the only condition that it should be bundled and can be launched using multiple ways like double click the bundle app or launching as a daemon using the unix executable?

I have created a progress indicator to simulate some progressing download task in the dock icon. However, I can see the progress bar appearing in the dock icon but it is not getting updated when I invoked the updateProgress() method. Ideally it should have updated it, and I m not able to figure out the reason? I have creating the same NSProgressIndicator on an NSWindow and it works to update the progress bar with the same code. Anything that I m missing to understand here? Below is the code I m using: class AppDelegate: NSObject, NSApplicationDelegate { var progressIndicator: NSProgressIndicator! let dockTile = NSApp.dockTile func applicationWillFinishLaunching(_ notification: Notification) { // Step 1: Create a progress bar (NSProgressIndicator) progressIndicator = NSProgressIndicator(frame: NSRect(x: 10, y: 10, width: 100, height: 20)) progressIndicator.isIndeterminate = false progressIndicator.minValue = 0.0 progressIndicator.maxValue = 100.0 progressIndicator.doubleValue = 0.0 progressIndicator.style = .bar dockTile.contentView = progressIndicator dockTile.display() //// Update the progress bar for demonstration DispatchQueue.main.asyncAfter(deadline: .now() + 1) { self.updateProgress(50) } } func updateProgress(_ value: Double) { progressIndicator.doubleValue = value NSApp.dockTile.display() } }

I am creating a UIKit application but that contains SwiftUI Views embedded using the hostingcontroller. I have a particular approach for it..but it requires instantiating a swiftUI view, creating a hostingcontroller object from it and storing a reference to it. So that later If I wanted to update the view, I can simply get the reference back and update the swiftUI view using it. I wanted to understand what does apple recommends on this. Can we store a swiftUI instance? Does it cause any issue or it is okay to do so?

Hi, need some help with an iOS application we are trying to make future safe. Basically, we know that our app would require SwiftUI so the app is made in that framework, however we require some important elements that are available only in UIKit, so we've made a bridge that allows us to pass UIKit views to SwiftUI to display them. So most of the app actually has UI made in UIKit, however, we now need to use the Charts framework present in SwiftUI, we've used SwiftUI buttons in our UIKit before by passing them through a HostingController (Passing SwiftUI buttons to UIKit to use). And we are currently considering to the same for SwiftUI Charts. Just to recap, it's a SwiftUI iOS app, that is mostly made in UIKit (through a bridge) but also has other SwiftUI elements injected into it. What we want to know that, is this the best way to do this? Or is there a better way to have UIKit and SwiftUI work more comfortably with eachother. The reason for such looping around is also because we interoping our C++ code to Swift for making this application, since we are making it for many other platforms and the business logic is in C++. Let me know if there are better ways to go about this!
