iOS Personal Utility App Development

I need a clean, easy-to-navigate iPhone app built strictly for personal use. This is not an e-commerce or social-networking project; the entire focus is on delivering a smooth, intuitive experience that makes everyday tasks quick and hassle-free.

Here is what I already know:
• The interface must feel native to iOS, respecting Human Interface Guidelines.
• Speed and simplicity outrank flashy extras—screens should load instantly, gestures must be fluid, and core actions should never be more than two taps away.
• All code has to be written in Swift, ready for Xcode 15, and structured so I can extend it later.

What I still need from you:
• End-to-end UI design (Figma or SwiftUI previews are both fine).
• Full implementation, including local data persistence (Core Data or Realm—whichever you prefer, just tell me why).
• A concise README explaining the project structure plus any third-party libraries you add via Swift Package Manager.

When we wrap up, I expect to have a fully running Xcode project that I can compile on my device, along with the design source files and build instructions. I am happy to clarify any edge cases once we start, but the headline goal is a personal app that feels as polished as something from the App Store.
