I have developed a number of apps over the years that use various Apple frameworks and technologies. I can work in Swift or Objective-C and am experienced in developing interfaces in UIKit and SwiftUI. Many of the apps I have developed hold 4+ star ratings in the AppStore and I have 400k downloads of the apps I have developed.
A few of the areas of development I have worked in are...
Communicating with REST API's
Using CoreLocation
User Notifications
MapKit
StoreKit
Tap To Pay
ARKit
