This iPhone and Apple Watch app connects to the Yale transit API to display bus arrival times at nearby stops. Run the iPhone app to query the API; keep the app in the foreground to query the API every minute. A list of buses will be displayed on the Apple Watch app.
The app runs on an iPhone and paired Apple Watch.
There are three parts to an Apple Watch project:
- The iPhone App, in this project called WatchKit Example. This contains the code for the companion iOS app.
- The WatchKit App, in this project called WatchKit Example WatchKit App. This contains the user interface for the watch app.
- The WatchKit Extension, in this project called WatchKit Example WatchKit Extension. This contains the logic for the watch app and the connection to the iOS app.
The TransitAPIModule singleton makes API requests. The LocationModule singleton tracks the user's location. The ViewController class initiates the API requests and sends the data to the watch app through an Application Context. The ScheduleInterfaceController receives this data, parses it, and instructs the user interface to display it.
The app is written in Swift 3 and targets watchOS 3. You must have a Mac with the latest version of Xcode installed. Clone this repo to get the code, and open the .xcodeproj file. The app will run in the simulator or on a connected device.
