ColorMatrix Type Failure - The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

[CrisFavero]

While building Macaw with xcode12-beta We get the build error The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions on line sixty in colorMatrix

So now we can use it in iOS 14.0 beta Thanks mate!
