Hello, I made a post earlier regarding a breakpoint error. This was fixed using a version hint. However, in solving the last problem, a new one has occured. Does anyone know how this can be solved?
The plugin I am creating is a panning dial which has been programmed through my college course. The campus computers are windows running Visual Studio however I am using Xcode on Mac. Would this potentially have caused this issue? Code below.
