Error:....... EPERM: operation not permitted, mkdi

The error message you encountered in Objective-C, "EPERM: operation not permitted, mkdi," indicates that the operation you are trying to perform is not permitted due to insufficient permissions. Specifically, the "mkdi" operation is likely a typo, as the correct operation is "mkdir" which is used to create a new directory.

To resolve this issue, you need to ensure that you have the necessary permissions to create a directory in the specified location. You can do this by checking the file system permissions and making sure you have the appropriate write permissions for the parent directory.

Here are the steps you can follow to troubleshoot and resolve this error:

1. Check the parent directory permissions: Verify that you have write permissions for the parent directory where you are trying to create the new directory. You can use the ls -l command to view the permissions of the parent directory and ensure that you have the necessary write permissions.

2. Use the correct command: Double-check that you are using the correct command to create a directory. In Objective-C, the correct command to create a directory is mkdir, not mkdi. Make sure you are using the correct command and syntax.

3. Run the command with appropriate permissions: If you do not have the necessary permissions to create a directory in the specified location, you can try running the command with elevated privileges. You can use the sudo command before the mkdir command to run it with root/administrator privileges. However, exercise caution when using elevated privileges, as it can have security implications.

By following these steps, you should be able to resolve the "EPERM: operation not permitted, mkdi" error in Objective-C.
