Ever stared at your screen, bewildered by the cryptic errordomain=nscocoaerrordomain&errormessage=ไม่พบคำสั่งลัดที่ระบุเฉพาะ&errorcode=4 error message? You’re not alone. This frustrating macOS error strikes when your system can’t find a specified shortcut, bringing your workflow to a screeching halt. While it might look intimidating (especially with that Thai text!), the fix is often more straightforward than expected.
This manual digs into the nitty-gritty of this error—what it means, why it happens, and most importantly, how to squash it for good. Whether building macOS apps or just trying to get your system running smoothly again, you’ll find practical, code-backed solutions here.
What Does errordomain=nscocoaerrordomain&errormessage=ไม่พบคำสั่งลัดที่ระบุเฉพาะ&errorcode=4 Actually Mean?
Let’s break down this error message component by component:
- ErrorDomain=NSCocoaErrorDomain: This indicates the error originates in Apple’s Cocoa framework, the foundation of macOS app development.
- ErrorMessage=ไม่พบคำสั่งลัดที่ระบุเฉพาะ: This Thai text translates to “Could not find the specified shortcut” – the heart of our problem.
- ErrorCode=4: In the NSCocoaErrorDomain, error code 4 refers explicitly to an issue with a file not found (NSFileNoSuchFileError).
Here’s how this error typically appears in logs:
Error Domain=NSCocoaErrorDomain Code=4 “ไม่พบคำสั่งลัดที่ระบุเฉพาะ” UserInfo={NSErrorFailingURLKey=file:///Users/username/Documents/shortcuts/myshortcut, NSErrorFailingURLStringKey=/Users/username/Documents/shortcuts/myshortcut, NSUnderlyingError=0x600003690f80 {Error Domain=NSPOSIXErrorDomain Code=2 “No such file or directory”}}
The error message might appear in Thai regardless of your system language because Apple’s localization sometimes gets mixed up when handling specific error types. It’s still the same underlying issue.
Common Causes of the errordomain=nscocoaerrordomain&errormessage=ไม่พบคำสั่งลัดที่ระบุเฉพาะ&errorcode=4 Error
1. Missing Shortcut Files
The most apparent cause is precisely what the error says – your app is trying to access a shortcut file that doesn’t exist where it’s expected.
Problematic Code:
swift
let fileURL = URL(fileURLWithPath: “/Users/dev/Documents/shortcuts/nonexistent.shortcut”)
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
Fixed Code:
swift
let fileURL = URL(fileURLWithPath: “/Users/dev/Documents/shortcuts/nonexistent.shortcut”)
if FileManager.default.fileExists(atPath: fileURL.path) {
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
} else {
print(“Shortcut file doesn’t exist at path: \(fileURL.path)”)
// Handle the missing file scenario
}
2. Incorrect File Permissions
Sometimes the shortcut file exists, but your app lacks permission to access it.
Problematic Code:
swift
let fileURL = URL(fileURLWithPath: “/Users/system/Library/shortcuts/protected.shortcut”)
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
Fixed Code:
swift
let fileURL = URL(fileURLWithPath: “/Users/system/Library/shortcuts/protected.shortcut”)
let fileManager = FileManager.default
// Check permissions before attempting to read
if fileManager.isReadableFile(atPath: fileURL.path) {
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error reading file: \(error)”)
}
} else {
print(“File exists but is not readable. Check permissions.”)
// Request permission or use an alternative approach
}
3. Path Resolution Issues
Relative paths or tilde expansion can cause unexpected failures.
Problematic Code:
swift
let fileURL = URL(fileURLWithPath: “~/Library/shortcuts/myshortcut.shortcut”)
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
Fixed Code:
swift
// Properly expand the tilde in the path
let tildeExpanded = NSString(string: “~/Library/shortcuts/myshortcut.shortcut”).expandingTildeInPath
let fileURL = URL(fileURLWithPath: tildeExpanded)
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
4. Sandbox Restrictions
If your app is sandboxed, it may be unable to access files outside its container.
Problematic Code:
swift
let fileURL = URL(fileURLWithPath: “/Users/shared/shortcuts/team.shortcut”)
do {
let data = try Data(contentsOf: fileURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
Fixed Code:
swift
// For a sandboxed app, use security-scoped bookmarks or file open panels
let openPanel = NSOpenPanel()
openPanel.allowedFileTypes = [“shortcut”]
openPanel.canChooseFiles = true
openPanel.canChooseDirectories = false
if openPanel.runModal() == .OK {
guard let selectedURL = openPanel.url else { return }
do {
// Start accessing security-scoped resource
guard selectedURL.startAccessingSecurityScopedResource() else {
print(“Failed to access security-scoped resource”)
return
}
defer { selectedURL.stopAccessingSecurityScopedResource() }
let data = try Data(contentsOf: selectedURL)
// Process the shortcut
} catch {
print(“Error: \(error)”)
}
}
Diagnosing the errordomain=nscocoaerrordomain&errormessage=ไม่พบคำสั่งลัดที่ระบุเฉพาะ&errorcode=4 Error
When you encounter this error, follow these steps to diagnose the issue:
Step 1: Examine the Full Error Output
Start by capturing and analyzing the complete error message:
swift
do {
// Code that might throw the error
} catch let error as NSError {
print(“Domain: \(error.domain)”)
print(“Code: \(error.code)”)
print(“Description: \(error.localizedDescription)”)
if let failingURL = error.userInfo[NSURLErrorFailingURLErrorKey] as? URL {
print(“Failing URL: \(failingURL)”)
}
if let underlyingError = error.userInfo[NSUnderlyingErrorKey] as? NSError {
print(“Underlying error: \(underlyingError)”)
}
// Print the entire error for additional clues
print(“Full error details: \(error)”)
}
Step 2: Verify File Existence and Permissions
Create a diagnostic utility function:
swift
func diagnoseFilePath(_ path: String) {
let fileManager = FileManager.default
print(“Diagnosing path: \(path)”)
// Check if file exists
if fileManager.fileExists(atPath: path) {
print(“✅ File exists”)
// Check permissions
if fileManager.isReadableFile(atPath: path) {
print(“✅ File is readable”)
} else {
print(“❌ File is not readable”)
}
// Get file attributes
do {
let attributes = try fileManager.attributesOfItem(atPath: path)
print(“File attributes:”)
for (key, value) in attributes {
print(” \(key): \(value)”)
}
} catch {
print(“❌ Error getting file attributes: \(error)”)
}
} else {
print(“❌ File does not exist”)
// Check if parent directory exists
let directory = (path as NSString).deletingLastPathComponent
if fileManager.fileExists(atPath: directory) {
print(“✅ Parent directory exists”)
// List contents of parent directory
do {
let contents = try fileManager.contentsOfDirectory(atPath: directory)
print(“Directory contents:”)
for item in contents {
print(” \(item)”)
}
} catch {
print(“❌ Error listing directory contents: \(error)”)
}
} else {
print(“❌ Parent directory does not exist”)
}
}
}
Step 3: Test File Access with Error Logging
swift
func testFileAccess(at path: String) {
let url = URL(fileURLWithPath: path)
do {
// Attempt to read the file
let data = try Data(contentsOf: url)
print(“✅ Successfully read \(data.count) bytes”)
} catch let error as NSError {
print(“❌ Failed to read file”)
// Check specific error conditions
if error.domain == NSCocoaErrorDomain && error.code == 4 {
print(” This is our target error: NSFileNoSuchFileError”)
// Parse the underlying POSIX error
if let underlyingError = error.userInfo[NSUnderlyingErrorKey] as? NSError,
underlyingError.domain == NSPOSIXErrorDomain {
switch underlyingError.code {
case 2:
print(” POSIX error: No such file or directory (ENOENT)”)
case 13:
print(” POSIX error: Permission denied (EACCES)”)
case 20:
print(” POSIX error: Not a directory (ENOTDIR)”)
default:
print(” POSIX error code: \(underlyingError.code)”)
}
}
}
print(” Full error details: \(error)”)
}
}

Conclusion
The errordomain=nscocoaerrordomain&errormessage=ไม่พบคำสั่งลัดที่ระบุเฉพาะ&errorcode=4 error stems from missing shortcut files or permission issues. Implement robust file-checking mechanisms before attempting access, and always include fallback strategies for alternative locations. The most critical takeaway is verifying file existence and proper permissions before reading file contents.
