Shapes drawing in swift based on Metal

,I m a french swiftUi engineer but with a limited swift drawing (path, bezier..) knowledge . Based on MaLiang pod, i have a basic ViewController to neon draw lines or neon hand draw . I need someone who would create a few shapes (triangle, grid..) , allow the user to zoom in /zoom out the shape and invert colors . All this is based on MaLiang/Metal.Good swift/swiftui level required (with drawing knowledges) . I don t need the full finished app, i need the features only .It is possible to start with one or two features if freelancer desires so
