Ever stared blankly at your screen while that cryptic Errordomain=nscocoaerrordomain&errormessage=impossible de trouver le raccourci indiqué.&errorcode=4 error mocks your development efforts? You’re not alone. This frustrating Cocoa framework error typically appears in macOS and iOS environments, bringing your application’s functionality to a screeching halt.
The error, roughly translating from French as “impossible to find the specified shortcut,” points to issues with file paths, permissions, or localization settings. Let’s dig into what’s causing this headache and how to squash it for good.
What Does Errordomain=nscocoaerrordomain&errormessage=impossible de trouver le raccourci indiqué.&errorcode=4 Error Actually Mean?
When you encounter the Errordomain=nscocoaerrordomain&errormessage=impossible de trouver le raccourci indiqué.&errorcode=4 error, you’re looking at three distinct components that hold the key to understanding the problem:
- errordomain=nscocoaerrordomain – This specifies that the error originates within Apple’s Cocoa framework, the macOS and iOS development application environment.
- errormessage=impossible de trouver le raccourci indiqué – The error message in French translates to “impossible to find the specified shortcut,” indicating that your application is trying to access a resource through a path or shortcut that doesn’t exist or isn’t accessible.
- errorcode=4 – In the NSCocoaErrorDomain, error code 4 corresponds to NSFileNoSuchFileError, confirming that the system cannot locate a specific file or resource.
This error typically appears in console output like this:
Error Domain=NSCocoaErrorDomain Code=4 “impossible de trouver le raccourci indiqué.”
UserInfo={NSFilePath=/Users/username/Documents/myapp/missing_resource.txt,
NSUnderlyingError=0x600002d9c770 {Error Domain=NSPOSIXErrorDomain Code=2 “No such file or directory”}}
Common Causes of the Errordomain=nscocoaerrordomain&errormessage=impossible de trouver le raccourci indiqué.&errorcode=4 Error
1. Incorrect File Paths or Missing Resources
The most frequent trigger for this error is simply pointing to a file that doesn’t exist where you think it does.
Problematic Code:
let fileURL = URL(fileURLWithPath: “/Users/developer/Documents/nonexistent.txt”)
do {
let data = try Data(contentsOf: fileURL)
// Process data
} catch {
print(error)
}
Solution:
let fileURL = URL(fileURLWithPath: “/Users/developer/Documents/correct_file.txt”)
if FileManager.default.fileExists(atPath: fileURL.path) {
do {
let data = try Data(contentsOf: fileURL)
// Process data
} catch {
print(error)
}
} else {
print(“File doesn’t exist at path: \(fileURL.path)”)
}
2. Insufficient Permissions
Your application might lack the necessary permissions to access certain files or directories.
Problematic Code:
let restrictedFileURL = URL(fileURLWithPath: “/Library/SystemPreferences/restricted.plist”)
do {
let contents = try String(contentsOf: restrictedFileURL, encoding: .utf8)
print(contents)
} catch {
print(error) // Will likely produce our error
}
Solution:
let fileURL = URL(fileURLWithPath: “/Library/SystemPreferences/restricted.plist”)
let fileManager = FileManager.default
// Check permissions before attempting to read
if fileManager.isReadableFile(atPath: fileURL.path) {
do {
let contents = try String(contentsOf: fileURL, encoding: .utf8)
print(contents)
} catch {
print(“Error reading file: \(error)”)
}
} else {
print(“No permission to read file at path: \(fileURL.path)”)
// Request appropriate permissions or use alternative approach
}
3. Localization Configuration Issues
Since the error appears in French, localization settings could be involved.
Problematic Code:
// Assuming French localization files are missing
let localizedString = NSLocalizedString(“ERROR_KEY”, comment: “Error message”)
label.text = localizedString // May not display correct text
Solution:
// Ensure all localization files exist
let localizedString = NSLocalizedString(“ERROR_KEY”,
tableName: “Errors”,
bundle: Bundle.main,
value: “Default error text if localization fails”,
comment: “Error message”)
label.text = localizedString
4. Bundle Resource Issues
Resources embedded in app bundles that can’t be located will trigger this error.
Problematic Code:
// Assuming “MissingImage.png” doesn’t exist in the bundle
if let imagePath = Bundle.main.path(forResource: “MissingImage”, ofType: “png”) {
let image = UIImage(contentsOfFile: imagePath)
imageView.image = image
}
Solution:
// Check if resource exists before attempting to use it
let resourceName = “AppIcon”
let resourceType = “png”
if let resourcePath = Bundle.main.path(forResource: resourceName, ofType: resourceType) {
if let image = UIImage(contentsOfFile: resourcePath) {
imageView.image = image
} else {
print(“Failed to create image from file: \(resourcePath)”)
}
} else {
print(“Resource \(resourceName).\(resourceType) not found in bundle”)
// Fall back to a default image
imageView.image = UIImage(named: “DefaultImage”)
}

How to Diagnose the Errordomain=nscocoaerrordomain&errormessage=impossible de trouver le raccourci indiqué.&errorcode=4 Error
When troubleshooting this error, follow these systematic diagnostic steps:
- Examine the complete error output
Start by capturing the full error details:
do {
try someOperationThatMightFail()
} catch let error as NSError {
print(“Domain: \(error.domain)”)
print(“Code: \(error.code)”)
print(“Description: \(error.localizedDescription)”)
print(“Failure Reason: \(String(describing: error.localizedFailureReason))”)
print(“Recovery Suggestion: \(String(describing: error.localizedRecoverySuggestion))”)
if let underlyingError = error.userInfo[NSUnderlyingErrorKey] as? NSError {
print(“Underlying error: \(underlyingError)”)
}
if let filePath = error.userInfo[NSFilePathErrorKey] as? String {
print(“File path: \(filePath)”)
}
}
- Verify file existence and accessibility
Create a diagnostic function to check file paths:
func diagnoseFilePath(_ path: String) -> [String: Any] {
let fileManager = FileManager.default
var results: [String: Any] = [:]
results[“exists”] = fileManager.fileExists(atPath: path)
results[“isReadable”] = fileManager.isReadableFile(atPath: path)
results[“isWritable”] = fileManager.isWritableFile(atPath: path)
results[“isExecutable”] = fileManager.isExecutableFile(atPath: path)
results[“isDeletable”] = fileManager.isDeletableFile(atPath: path)
do {
let attributes = try fileManager.attributesOfItem(atPath: path)
results[“size”] = attributes[.size]
results[“creationDate”] = attributes[.creationDate]
results[“modificationDate”] = attributes[.modificationDate]
results[“ownerAccountName”] = attributes[.ownerAccountName]
results[“posixPermissions”] = attributes[.posixPermissions]
} catch {
results[“attributesError”] = error.localizedDescription
}
return results
}
// Usage
let pathToCheck = “/Users/username/Documents/myapp/resource.txt”
let diagnosticResults = diagnoseFilePath(pathToCheck)
print(“File diagnostics: \(diagnosticResults)”)
- Check bundle resources
Verify that bundle resources are correctly included:
func listBundleResources(withExtension ext: String? = nil) {
guard let resourceURLs = Bundle.main.urls(forResourcesWithExtension: ext, subdirectory: nil) else {
print(“No resources found with extension: \(ext ?? “any”)”)
return
}
print(“Found \(resourceURLs.count) resources:”)
for (index, url) in resourceURLs.enumerated() {
print(“\(index + 1). \(url.lastPathComponent)”)
}
}
// Usage
listBundleResources(withExtension: “png”)
