My iOS app is stable and feature-complete, but the interface feels dated. I want a fresh, modern look that fits current Apple design standards without disturbing existing functionality. The refresh must cover: • Navigation menu – smoother flow, clearer hierarchy, and gesture-friendly behavior. • Home screen layout – more engaging first impression, adaptive to every iPhone size with Auto-Layout. • Buttons and icons – new asset set that is crisp, consistent, and SF Symbol-aware. I will give you the current Xcode project and asset catalogue. Your job is to redesign these elements, implement them in Swift / UIKit (or SwiftUI if more efficient), and return a build that compiles in the latest Xcode, passes TestFlight, and shows no functional regressions. Deliverables: 1. Updated source project with all UI changes. 2. Optimized image assets and vector icons. 3. A brief hand-off note explaining any new classes or storyboards. Please highlight previous iOS UI work in your proposal and let me know your approximate timeline for completing the redesign.
