# Error code: 07

This error occurs when the API Key that was generated the last time for compiling for iOS is already invalid; therefore, the system will request that you add a new API Key.

NOTE: When the system requests the API Key again, do not enter the old one since it is invalid. You need to create a new one and add it.

To resolve the problem, follow the steps indicated below:

Step 1: Follow steps 1 to 14 in this guide to generate a new API Key for iOS: [Compile version in TestFlight](/global-functions-1/ios.md), and then proceed with compiling.

Compile again, if the compilation processes successfully, the problem has been resolved. If it returns an error or presents another issue during the key deletion process, proceed to the next step.
