Update UI of Objective C App ( 19 Screens ) – " I have figma design " — 2

I am looking for experienced developers for the UI update of an existing Objective C App. The app consists of 19 screens and I have the Figma design available. The updates needed are more than just minor changes in color or size; they will involve a substantial overhaul. I already have a specific look in mind, so no assumptions need to be made as far as creative direction. I am simply looking for an experienced coders to bring my vision to life. The deadline for this project is more than 4 weeks.
