I will fix ios app bugs and optimize swift and swiftui performance
Simon
About this gig
I am an iOS developer (Swift, SwiftUI, Objective-C, UIKit) with experience as an Expert Software Developer at Shopee. I fix crashes, UI bugs and slow performance in existing iOS apps, and I optimise memory and launch performance. What you get depends on the package: diagnosis and a fix for a single issue, multiple fixes with performance tuning, or deep performance and memory optimisation with regression testing. I work from your reproduction steps and code, and I deliver clean, documented changes. This gig covers code fixes only, not App Store submission unless stated in the Premium package notes.
