Same issue on iOS, current master branch:

Passing empty image buffer data.
[api] -[CIRenderDestination initWithBitmapData:width:height:bytesPerRow:format:] requires a valid data argument.
[api] -[CIContext(CIRenderDestination) _startTaskToRender:toDestination:forPrepareRender:forClear:error:] The destination is nil.

@zhengcan 's fix in the PR looks good to me but shouldn't it also be applied in the corresponding place in ios/Classes/MobileScanner.swift ? Or is the underlying issue of null texture ids only a MacOS problem?

I have released version 3.0.0 which should fix this issue.
