 Sequent OXYGO:

Refactor the app from storyboard to SwiftUI alone. The APP is used with a smartphone, which can make users know their physical condition, like Heart Rate , Daily Steps, Sleep Status, and record the sports details to provide a better control of your health.

Implemet:

I use SwiftUI within MVVM to build the View, and combine the data in with a viewmodel like notification or data source from backend. I also need to use BLE 4.2 to exchange the raw data from the phone to the watch and then store  the data in CoreData. To record more information from users, we also have some algorithms for GPS accuracy. Also, we need to draw some charts to present the heart rate, sleep status and daily steps that make the user easily understand the details of activities.
