The main subject of the project is SmoothBezier struct.
SmoothBezier struct automatically generating bezier control points for perfect smoothing (purple dots) Points for initializer are ralative values from 0 to 1 inside bounds (height and width) for ease of size changing. You don't need to update all coordinates if you want to change shape size, just set bounds!
SmoothBezier init (
points: [[CGFloat]], // Array of points in simple format [ [x, y], [x, y], [x, y], [x, y] ... ]
boundsWidth: CGFloat, // Full width of shape
boundsHeight: CGFloat, // Full height of shape
margin: CGFloat = 0, // Margin from bounds inside (makes real shape smaller)
smoothinessRatio: CGFloat = 33 // Level of smoothiness. 0 will give you corners.
)
