@warrenm Do I need both a vertex and a fragment shader like I do with GLSL? My base template has no vertex buffer to be shaded.

@warrenm@RedQueenCoder I meant, “why is the vertex function not an implicitly unwrapped optional, instead of a regular question mark one?”.
@jessyMeow Consistency? Also, the framework never assumes vertexFunction is non-nil; it checks the invariant to provide a helpful message.

@warrenm@jessymeow print(vertexFunction) gives the "fatal error: unexpectedly found nil while unwrapping an Optional value" which is right.Thanks. Twitter will use this to make your timeline better. UndoUndo
