iWatch & Unity bridge gig

Deadline: 1st August 2021

Make a well documented SDK/package for bridging a cross-platform Unity project generated iOS App and iWatch modules of the same app, with error handling:
Able to communicate between iOS Unity App module and iWatch App module without delay. Presumably via WatchConnectivity or faster method. With an example demo code.
Able to keep sending raw data from iWatch App module (i.e., CoreMotion Acceleration data) to Unity project generated iOS App module at an interval (i.e., 0.1s) without delay. Prevent iWatch from sleeping until the task is stopped, not affected by external interruption (notification viewing, alert, etc.), and is able to continue doing so in the background.
With an example demo code including but not limited to all of the following data:
○ Accelerometer (x,y,z)
○ Gyroscope (x,y,z,yaw,pitch,roll)
○ Magnetometer
○ Barometer
○ Other data from CoreMotion
○ ForceTouch force measuring
○ Heart Rate reading
○ ECG
○ Blood Oxygen
○ Pedometer
○ Data from HealthKit
○ Battery level
○ GPS data
○ Model of the iWatch
○ The availability of the above sensor and above data.
