SevenLakes asked us to maintain and develop their iOS oil well management app, FDG. The app captures data, including wells, tanks, metres, equipment, EH&S, chemicals, run ticket images, and geo-location tags. We upgraded code architecture and design patterns while maintaining and debugging the code. We have streamlined the app's variations, previously done on a client-to-client basis, into a single app encompassing all features.
The existing app had been under development for a long time. As such, the code base was primarily written in Objective C libraries, adopting to Objective-C and helping to migrate to Swift with crash free / testable code was challenging. On the other hand, the recent developments in Swift language and the commonly adopted design patterns were added to make it scalable. Furthermore, debugging was tricky when both Swift and Objective C are present in the code in substantial amounts.
