When developing applications using Apple’s Cocoa development framework, errors and issues may arise. Cocoa provides a mechanism for reporting and resolving these errors. The error domain and message that are generated when these errors occur can help developers determine the cause of the error. This article will discuss common error domains and error messages associated with Cocoa, as well as provide a few tips for resolving them.
Error Domain
The NSPOSIXErrorDomain&errormessage=could not find the specified sh error message can be very frustrating to Mac users, especially those with a high-end desktop computer. This is usually caused by a third-party firewall, internet security or computer security program on a Mac that prevents some or all of the system’s applications from connecting to the internet.
The best way to resolve the issue is by uninstalling the third-party firewall or internet security application from your device completely. This will remove any associated files and also make the problem go away for good. You should then reboot your device by clicking on the Apple logo in the top menu bar and selecting Restart.
This method can be repeated as often as needed to remove the error from your device. However, if you notice that it comes back every time after you’ve tried to uninstall the program, try replacing it with an eligible alternative instead.
Another possible cause of the NSPOSIXErrorDomain&errormessage=couldnot find the specified sh error is if there are special characters in the path name that are being interpreted by the Command Prompt. These are typically operators and other non-human-readable symbols that the Command Prompt may not be able to interpret correctly.
A simple fix is to rename the file in question and remove any special characters from its name. This will ensure that the Command Prompt will be able to properly interpret its path name and will not throw this error again.
Finally, if this error is being thrown because you’re running incorrect code in the Command Prompt, you can fix the problem by reviewing the compiled code and making sure that it’s not doing anything wrong. If it is, you can re-run the code and change any faulty parts of it to correct the issue.
Creating error messages that are clear, easy to understand, and on brand will help you communicate with your target audience. This will result in more positive interactions with your users and a faster bottom line. For more information, check out our guide to writing error messages for the web.
Error Message
When an error message appears, it should describe the problem in a way that users can understand. It should also tell users what caused the problem and what they can do to resolve it.
Error messages should be written in user-friendly UX writing language, so that users can read them quickly and easily. They should follow Spectrum’s in-product voice principles of Rational (clear and understandable), Human (friendly, honest), and Focused (concise and simple).
The best error messages are short, clear, and simple. They explain what the error is, why it happened, and when possible, provide a solution to fix it.
Providing a quick and concise explanation of an error is important because it empowers users to take action on their own and solve problems in a timely manner. It allows users to get back to the work they want to do without getting caught up in technical details that may be meaningless or even confusing for them.
For example, a user might rename a file because they discovered that another file had the same name and wanted to change it. A user can then use the error message to find out why the renamed file failed and what to do next.
This example from Windows XP is a terrible error message. It not only blames the user for a problem that they didn’t cause, but it prevents Windows from shutting down, a potentially dangerous situation.
When errors are displayed, set input focus to the first control that has incorrect data so that the user can see what the problem is and correct it. If possible, allow the user to scroll the control into view or select the entire contents so that they can correct the problem without having to start over.
Avoid using negative words in error messages unless the error is catastrophic. Some style guides prefer a friendly tone rather than choosing positive words so consult your company’s style guide to be sure.
Whenever possible, include a link to Help content in an error message or in the Help button. This can help users to learn more about the problem and the solution to it, which may lead them to search the Internet or contact a support agent for further assistance.
