How To Fix Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4 Error?
You're coding away when suddenly this cryptic error appears: Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4. Frustrating, right? This NSCocoaErrorDomain error strikes macOS and iOS developers when their applications can't locate specific shortcuts or resources.
This error typically manifests during file operations or resource access attempts. Your app might be searching for a particular shortcut but can't find it in the expected location. The Japanese error message translates to “specified shortcut was not found,” – giving you a clear hint about what's wrong.
We'll walk you through proven solutions that actually work. No generic advice here – just specific fixes that address this exact error code.
What Does Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4 Really Mean?
Breaking down this error message reveals its true nature. NSCocoaErrorDomain represents Apple's Cocoa framework error category. All macOS and iOS development errors fall under specific domains for better categorization.
The Japanese text “指定されたショートカットが見つかりませんでした” directly translates to “specified shortcut was not found.” Error code 4 specifically indicates a file or resource access failure within the NSCocoaErrorDomain family.
Here's how the error appears in your console:
Error Domain=NSCocoaErrorDomain Code=4 “指定されたショートカットが見つかりませんでした。”
UserInfo={NSLocalizedDescription=指定されたショートカットが見つかりませんでした。}
This error typically occurs during:
- File path resolution attempts
- Resource bundle access
- Shortcut file interactions
- Application launch sequences
Common Causes of Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4
1. Missing Shortcut Files
Your application expects a shortcut file that's been deleted or moved. This commonly happens when:
// Problematic code
let shortcutPath = Bundle.main.path(forResource: “MyShortcut”, ofType: “shortcut”)
// Returns nil if file doesn't exist
Solution:
// Safe approach with error handling
if let shortcutPath = Bundle.main.path(forResource: “MyShortcut”, ofType: “shortcut”) {
// File exists, proceed safely
processShortcut(at: shortcutPath)
} else {
// Handle missing file gracefully
createDefaultShortcut()
}
2. Incorrect Bundle Resource References
Bundle references pointing to non-existent resources trigger this error frequently:
// This can fail silently
let resourceURL = Bundle.main.url(forResource: “config”, withExtension: “plist”)
let data = try Data(contentsOf: resourceURL!) // Crashes if nil
Corrected version:
guard let resourceURL = Bundle.main.url(forResource: “config”, withExtension: “plist”) else {
throw NSError(domain: NSCocoaErrorDomain, code: 4, userInfo: [
NSLocalizedDescriptionKey: “Configuration file not found”
])
}
let data = try Data(contentsOf: resourceURL)
3. Permission Access Issues
Applications lacking proper permissions can't access certain shortcuts:
// Risky code without permission checks
func accessShortcut(at path: String) {
let url = URL(fileURLWithPath: path)
// Direct access might fail
let content = try String(contentsOf: url)
}
Improved implementation:
func accessShortcut(at path: String) throws {
let url = URL(fileURLWithPath: path)
// Check file accessibility first
guard FileManager.default.isReadableFile(atPath: path) else {
throw NSError(domain: NSCocoaErrorDomain, code: 4, userInfo: [
NSLocalizedDescriptionKey: “指定されたショートカットが見つかりませんでした。”
])
}
let content = try String(contentsOf: url)
}
4. Sandbox Restriction Violations
macOS sandboxing can prevent shortcut access outside allowed directories:
// This might fail in sandboxed apps
let documentsPath = NSHomeDirectory().appending(“/Documents/shortcuts/”)
// Sandbox restrictions may block access
Sandbox-compliant approach:
let documentsURL = FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first!
let shortcutsURL = documentsURL.appendingPathComponent(“shortcuts”)
// Use bookmark data for persistent access
Prevention vs. Recovery Strategies
Prevention Techniques | Recovery Strategies |
Bundle resource validation during build | Graceful error handling with user notifications |
Sandbox entitlement configuration | Alternative resource path fallbacks |
Permission request implementation | Default resource creation when missing |
Resource existence verification | Error logging with diagnostic information |
Unit testing for missing resources | User-guided file restoration prompts |
Build-time asset verification | Automatic shortcut regeneration |
Diagnosing Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4
Follow this systematic diagnostic approach to identify the root cause:
Step 1: Enable Detailed Error Logging
func logDetailedError(_ error: Error) {
if let nsError = error as NSError? {
print(“Error Domain: \(nsError.domain)“)
print(“Error Code: \(nsError.code)“)
print(“Error Description: \(nsError.localizedDescription)“)
print(“User Info: \(nsError.userInfo)“)
// Log stack trace for debugging
Thread.callStackSymbols.forEach { print($0) }
}
}
Step 2: Implement Resource Verification
extension Bundle {
func verifyResource(name: String, type: String) -> Bool {
let path = self.path(forResource: name, ofType: type)
let exists = path != nil && FileManager.default.fileExists(atPath: path!)
if !exists {
print(“Missing resource: \(name).\(type)“)
}
return exists
}
}
Step 3: Create Diagnostic Tests
class ShortcutDiagnostics {
static func runDiagnostics() {
let expectedShortcuts = [“launcher”, “settings”, “preferences”]
expectedShortcuts.forEach { shortcut in
if !Bundle.main.verifyResource(name: shortcut, type: “shortcut”) {
// Log missing shortcut details
let error = NSError(domain: NSCocoaErrorDomain, code: 4, userInfo: [
NSLocalizedDescriptionKey: “指定されたショートカットが見つかりませんでした。”,
“MissingResource”: “\(shortcut).shortcut”
])
logDetailedError(error)
}
}
}
}
Implementing Robust Error Handling for Missing Shortcuts
Create a comprehensive solution that prevents and handles this error effectively:
import Foundation
class ShortcutManager {
static let shared = ShortcutManager()
private let errorDomain = “com.yourapp.shortcut”
// MARK: – Error Types
enum ShortcutError: Error {
case notFound(String)
case invalidFormat(String)
case permissionDenied(String)
var nsError: NSError {
switch self {
case .notFound(let name):
return NSError(domain: NSCocoaErrorDomain, code: 4, userInfo: [
NSLocalizedDescriptionKey: “指定されたショートカットが見つかりませんでした。”,
“ShortcutName”: name
])
case .invalidFormat(let name):
return NSError(domain: errorDomain, code: 5, userInfo: [
NSLocalizedDescriptionKey: “Shortcut format is invalid: \(name)“
])
case .permissionDenied(let name):
return NSError(domain: errorDomain, code: 6, userInfo: [
NSLocalizedDescriptionKey: “Permission denied for shortcut: \(name)“
])
}
}
}
// MARK: – Safe Shortcut Access
func loadShortcut(named name: String, completion: @escaping (Result<Data, Error>) -> Void) {
DispatchQueue.global(qos: .userInitiated).async {
do {
let data = try self.validateAndLoadShortcut(named: name)
DispatchQueue.main.async {
completion(.success(data))
}
} catch {
DispatchQueue.main.async {
completion(.failure(error))
}
}
}
}
private func validateAndLoadShortcut(named name: String) throws -> Data {
// Step 1: Check bundle for shortcut
guard let resourcePath = Bundle.main.path(forResource: name, ofType: “shortcut”) else {
// Step 2: Try Documents directory
let documentsURL = FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first!
let shortcutURL = documentsURL.appendingPathComponent(“\(name).shortcut”)
if !FileManager.default.fileExists(atPath: shortcutURL.path) {
throw ShortcutError.notFound(name)
}
return try Data(contentsOf: shortcutURL)
}
// Step 3: Verify permissions
guard FileManager.default.isReadableFile(atPath: resourcePath) else {
throw ShortcutError.permissionDenied(name)
}
return try Data(contentsOf: URL(fileURLWithPath: resourcePath))
}
// MARK: – Fallback Creation
func createDefaultShortcut(named name: String) throws {
let documentsURL = FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first!
let shortcutURL = documentsURL.appendingPathComponent(“\(name).shortcut”)
let defaultShortcut = “””
{
“version”: “1.0”,
“name”: “\(name)“,
“type”: “default”,
“actions”: []
}
“””.data(using: .utf8)!
try defaultShortcut.write(to: shortcutURL)
}
}
// MARK: – Usage Example
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
ShortcutManager.shared.loadShortcut(named: “launcher”) { result in
switch result {
case .success(let data):
// Handle successful shortcut loading
self.processShortcutData(data)
case .failure(let error):
// Handle Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4
self.handleShortcutError(error)
}
}
}
private func handleShortcutError(_ error: Error) {
if let shortcutError = error as? ShortcutManager.ShortcutError {
switch shortcutError {
case .notFound(let name):
// Attempt to create default shortcut
do {
try ShortcutManager.shared.createDefaultShortcut(named: name)
showSuccess(“Created default shortcut: \(name)“)
} catch {
showError(“Failed to create shortcut: \(error.localizedDescription)“)
}
default:
showError(error.localizedDescription)
}
}
}
}
// MARK: – Unit Tests
import XCTest
class ShortcutManagerTests: XCTestCase {
func testMissingShortcutError() {
let expectation = self.expectation(description: “Missing shortcut error”)
ShortcutManager.shared.loadShortcut(named: “nonexistent”) { result in
switch result {
case .failure(let error):
XCTAssertEqual((error as NSError).domain, NSCocoaErrorDomain)
XCTAssertEqual((error as NSError).code, 4)
expectation.fulfill()
case .success:
XCTFail(“Should have failed for missing shortcut”)
}
}
waitForExpectations(timeout: 5.0)
}
}
Key Takeaways
The Errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errorcode=4 error occurs when your app can't find the expected shortcut files. Always implement robust error handling that checks for resource existence before attempting access.
Your most critical implementation step: create a fallback mechanism that generates default shortcuts when the expected ones are missing. This prevents app crashes and maintains functionality even when resources are unavailable.
