In the realm of software development, encountering errors is an inevitable part of the process. One such error that developers may come across is the “Errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4” message. In this article, we will dissect this error message, explore its components, and discuss potential causes and solutions.

Understanding the Error Message: Let’s break down the components of the error message:

  1. Errordomain=nscocoaerrordomain:
    • “Errordomain” refers to the domain of the error, and in this case, it is set to “nscocoaerrordomain.” Cocoa is Apple’s native object-oriented application programming interface (API) for their macOS and iOS operating systems. NSCocoaErrorDomain is a predefined domain for Cocoa errors.
  2. Errormessage=could not find the specified shortcut:
    • The “Errormessage” provides a description of the error, indicating that the specified shortcut could not be found. This suggests that there might be an issue related to a keyboard shortcut or a similar user-defined action within the application.
  3. Errorcode=4:
    • The “Errorcode” specifies a numerical identifier for the error. In this case, the code is set to “4,” which can serve as a reference point for developers to identify the exact nature of the problem.

Potential Causes: Several factors could contribute to this error message:

  1. Incorrect Shortcut Configuration:
    • Developers should check whether the specified shortcut is correctly configured within the application. It might be possible that the assigned keyboard combination is not registered or conflicts with another function.
  2. Missing or Corrupted Shortcut Data:
    • If the application relies on a configuration file or database to store shortcut information, the error could occur if this data is missing or corrupted. Developers should verify the integrity of the data storage mechanism.
  3. Programming Logic Errors:
    • Bugs in the application’s code, especially in the section responsible for handling shortcuts, could lead to the error. Thorough code review and debugging are essential to identify and rectify such issues.

Solutions: To address the “Errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4” error, developers can consider the following solutions:

  1. Review Shortcut Configuration:
    • Double-check the configuration of the specified shortcut within the application settings. Ensure that it is correctly defined and does not conflict with other shortcuts or system functions.
  2. Verify Data Integrity:
    • If the application relies on external data for shortcut configuration, verify the integrity of the data source. Repair or replace any missing or corrupted data.
  3. Debugging and Error Handling:
    • Implement robust error handling mechanisms in the code to catch and log errors effectively. Use debugging tools to trace the execution flow and identify any logical errors in the shortcut-handling code.

The error message you provided, “Errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4,” indicates that a specific shortcut or key combination you tried to use was not found by the system. This can happen for several reasons:

1. Invalid or deleted shortcut:

  • The shortcut you used might have been deleted accidentally or moved to a different location.
  • The application you’re using might have updated, and the shortcut is no longer valid.
  • You might have mistyped the shortcut key combination.

2. Permissions issues:

  • You might not have enough permissions to access the file or folder associated with the shortcut.

3. Software conflicts:

  • Other applications running on your system might be interfering with the shortcut.

4. System or application issues:

  • There could be a bug in the application you’re using or in the operating system itself.

Here’s what you can do to troubleshoot the issue:

1. Check the shortcut:

  • Verify the exact shortcut you’re trying to use. Check for any typos or mistakes in the key combination.
  • Look for the shortcut settings within the application and make sure it’s defined correctly.

2. Update the application and macOS:

  • Make sure you’re using the latest version of the application and macOS. Updates often fix bugs and compatibility issues.

3. Check permissions:

  • If the shortcut is related to a specific file or folder, ensure you have the necessary permissions to access it.

4. Restart the application and your device:

  • Sometimes a simple restart can clear temporary glitches and resolve the issue.

5. Contact the app developer or support:

  • If none of the above steps work, reach out to the developer of the application you’re using or Apple support for further assistance.

Additional information needed:

To provide more specific guidance, it would be helpful if you could tell me:

  • What application or context were you using the shortcut in when the error occurred?
  • Have you recently made any changes to your system or the application?
  • Have you tried any other troubleshooting steps?

Hello, I’m trying to save some Strings in a csv document:

        var tempString = String()
        for Rezept in alleRezepte {
            tempString += "\(, \(Rezept.description), \(Rezept.nutrients), \(Rezept.whatToDo)\n"
        let dirs = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .allDomainsMask, true) as? [String])
        let path = dirs?[0].appending("rezepte.csv")
        let url = URL(string: path!)
        do {
            try tempString.write(to: url!, atomically: true, encoding: String.Encoding.utf8)
        } catch {
        print("Daten gesichert")

And I get this error:

CFURLCopyResourcePropertyForKey failed because it was passed an URL which has no scheme

Error Domain=NSCocoaErrorDomain Code=518 “The file couldn’t be saved because the specified URL type isn’t supported.”

hat QuinceyMorris said but also…

The specific cause of your problem is line 7. If you want to go from a path to a file URL, you need to use


. What you have,


, creates a URL with a path component but no scheme, and that’s what’s triggering the specific error you’ve got.

QuinceyMorris’s advice is correct though: life is much easier if you go ‘all in’ on URLs. I just posted an example on your other thread.
