    I have an iOS prototype written entirely in SwiftUI that’s almost ready for prime time, but a few pain-points are holding it back from the App Store. Right now I’m seeing: i made it in openai-codex- i need someone look at the prototype i made, make sure no bugs, all smooth, works well and launch it in the app store - i also need the code from them and access in order to maintain it myself - make sure its all working well efficiently and clean. Launch in app store. then give me code and all for it to maintain myself. Also want someone who can do it in one chunk and happy pay the one off. not paying hourly or extras. • Crashes in several flows • Performance lags on older devices • UI/UX problems that make some screens feel rough Your mission is t...
