The messages tell you what’s wrong with your code. We can’t see your code so we can’t tell what’s wrong with it. But it could be that you are using functions before declaring them, or that you’re using the archaic non-prototype notation to define them. – Jonathan Leffler Aug 13 '23 at 14:23

Also, don’t post images of text error messages. – Jonathan Leffler Aug 13 '23 at 14:26

Please review [these search results](https://stackoverflow.com/search?q=xcode+A+function+declaration+without+a+prototype+is+deprecated+in+all+versions+of+C) on the error. BTW - this is why you should not post error messages as pictures. No one can search on your question because the error isn't in your question or title anywhere (as text). – HangarRash Aug 13 '23 at 16:31
