Difference between Error Domain & Error code:-
Error Domain:
An error domain is a way to categorize errors based on their source or origin within a software system. It helps identify which part of the system generated the error. For example, in iOS development, errors are often categorized into different domains, such as NSURLErrorDomain for errors related to network operations, or NSCocoaErrorDomain for errors related to Cocoa framework operations.
Error Code:
An error code is a numeric or alphanumeric identifier that provides more specific information about the error within a given error domain. For instance, within the NSURLErrorDomain, you might encounter error codes like NSURLErrorBadURL (indicating that the URL provided is malformed) or NSURLErrorTimedOut (indicating a timeout occurred during a network request).
Error Message: Opgegeven Opdracht Niet Gevonden
The error message “Opgegeven Opdracht Niet Gevonden” is in Dutch, and it translates to “Specified Command Not Found” in English. It indicates that a requested command or operation could not be found or recognized by the system. errordomain=nscocoaerrordomain&errormessage=opgegeven opdracht niet gevonden.&errorcode=4
This error message often appears in interactive command-line or terminal environments. It indicates that the user attempted to run an operation that the OS does not recognize or what is not available in the present context.
It is vital to double-check the instruction for typos or errors and to ensure that you are using an appropriate phrase in the particulars of the system that you work with.
