Description

The TouchMoved() block is evaluating twice for each time touch has moved. I can confirm by printing out the touch.x and touch.y parameters from the this block - it always prints it out twice (but never more than that).

Research direction

Start by tracing the iOS touch-event path that invokes TouchMoved(), then reproduce the report with logging for touch.x and touch.y. Confirm whether one physical movement produces two callback evaluations and identify the relevant event-handling location; done means each movement evaluates TouchMoved() once.
