Help with MacOS app programming

Hi, I'm looking for a talented programmer to help with my MacOS app. The app is currently written in Swift and I need an expert who can work with the existing code to help me improve it. I'm specifically looking for help with bug fixes (memory leaks) and code optimization. The ideal candidate will also be able to show me what I'm doing wrong, even when it works! The programmer must be experienced with Swift, as well as familiar with the MacOS system. If you feel you have the skills and experience needed, please apply. Thank you.
