I’m a software developer based in London and Sevenoaks, UK, where I’m currently creating iOS and macOS apps with Swift, SwiftUI and UIKit. I have over 35 years experience in the industry in many different roles and with a range of technologies.

Retreev

When you really need a ride home

Retreev was developed in reponse to a simple, but common problem: how to quickly and easily request a ride home from a parent or friend and let them know exactly where you are!

The app displays a map showing your current location and postal address. Tapping a contact zooms the map to show the location of both you and the contact, as well as the distance between you. Tapping the “retreev” button generates an SMS message that includes a predefined (editable) message, your current location address and an annotated map showing the location and distance.

The app was developed in Swift and UIKit and uses the Contacts framework to import user-selected contact details and CoreLocation to Geocode (get lat/long from an address) and Reverse Geocode (get address from lat/long).
