Convert Android App to iOS

I need an experienced developer to convert my Android app into an iOS version, specifically for iPhone.

Key functionalities of the Android app:
- User Authentication
- Push Notifications
- In-app Purchases

I have all the design assets ready for the iOS version, so you won't need to create anything from scratch.

Ideal skills and experience for the job:
- Proficient in Swift and Objective-C
- Experience with iOS app development
- Familiarity with integrating user authentication, push notifications, and in-app purchases
- Knowledgeable in handling app design assets
- Strong attention to detail and commitment to delivering a high-quality product.
