Crash When Clicking on Definition View Created by AppKit's showDefinition(for:at)
I'm encountering a crash issue in my macOS application when clicking on the view generated by AppKit's showDefinition(for:at) function. I'm seeking assistance to resolve this issue. **Problem Description: ** I'm developing a macOS application where I utilize the showDefinition(for:at) function provided by AppKit to display the definition view of words. However, whenever I click on this view, the application crashes abruptly. **Error Message: ** The crash log reveals the following error message: Fault: deferNSXPCInvocationOntoMainThread_block_invoke caught NSInternalInconsistencyException '_CPSSetFrontProcessWithOptions failed due to CGError -606 4294966690 fffffda2 (appIsDaemon)' Attempts Made: Tried wrapping relevant code blocks with DispatchQueue.main.async, suspecting a threading issue. Making the DefinitionWindow variable a global one to manually control its lifecycle Development Environment: macOS Version: 14.3.1 Xcode Version: 15 Below is a complete and reproducible code snippet that can be directly executed within a terminal project template. Please note that it requires Accessibility permissions to be granted in the Privacy settings. import Cocoa import SwiftUI import AppKit class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ notification: Notification) { NSEvent.addGlobalMonitorForEvents(matching: .keyDown) { [weak self] event in guard let self = self else { return } if event.modifierFlags.contains(.command) && event.charactersIgnoringModifiers == "c" { self.ShowWordDefinition() } } NSApp.servicesProvider = self NSApp.registerServicesMenuSendTypes([.string], returnTypes: []) } func ShowWordDefinition(){ DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) { let attributedString = NSAttributedString(string:NSPasteboard.general.string(forType: .string)!) let DefinitionWindow = NSWindow(contentRect: NSRect(origin: .zero, size: NSSize(width: 1, height: 1)), styleMask: [.borderless], backing: .buffered, defer: false) // on the top DefinitionWindow.level = .floating let pointInWindow = NSPoint(x:0,y:0); //default value DefinitionWindow.contentView?.showDefinition(for: attributedString, at: pointInWindow) DefinitionWindow.orderFront(nil) } } } let delegate = AppDelegate() let app = NSApplication.shared app.delegate = delegate app.run() full crash log reveals the following error message: FAULT: deferNSXPCInvocationOntoMainThread_block_invoke caught NSInternalInconsistencyException '_CPSSetFrontProcessWithOptions failed due to CGError -606 4294966690 fffffda2 (appIsDaemon)' with backtrace ( "0 CoreFoundation __exceptionPreprocess + 176", "1 libobjc.A.dylib objc_exception_throw + 60", "2 CoreFoundation +[NSException exceptionWithName:reason:userInfo:] + 0", "3 ViewBridge assertCGError + 80", "4 ViewBridge -[NSRemoteView _serviceWindowWouldActivate] + 724", "5 CoreFoundation __invoking___ + 148", "6 CoreFoundation -[NSInvocation invoke] + 428", "7 ViewBridge __deferNSXPCInvocationOntoMainThread_block_invoke + 120", "8 ViewBridge __wrapBlockWithVoucher_block_invoke + 56", "9 ViewBridge deferredBlockOpportunity_block_invoke_2 + 360", "10 CoreFoundation __CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK__ + 28", "11 CoreFoundation __CFRunLoopDoBlocks + 356", "12 CoreFoundation __CFRunLoopRun + 2440", "13 CoreFoundation CFRunLoopRunSpecific + 608", "14 HIToolbox RunCurrentEventLoopInMode + 292", "15 HIToolbox ReceiveNextEventCommon + 648", "16 HIToolbox _BlockUntilNextEventMatchingListInModeWithFilter + 76", "17 AppKit _DPSNextEvent + 660", "18 AppKit -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 716", "19 AppKit -[NSApplication run] + 476", "20 try main + 160", "21 dyld start + 2360" ) Just a reminder, the application will crash when you click on the displayed definition window. Potential Questions and Concerns: Could there be an issue related to UI transitions or the main thread? How exactly does the showDefinition(for:at) process work internally? Maybe , the view's display level being raised when clicked caused conflict? If anyone could provide any insights or guidance on resolving this issue, it would be greatly appreciated. Thank you!
