Declaration 宣言 

func draw(_ symbol: GraphicsContext.ResolvedSymbol, at point: CGPoint, anchor: UnitPoint = .center)

Parameters パラメータ

symbol

point

A point within the rectangle of the resolved symbol to anchor to a point in the context.

anchor

A UnitPoint within the context to align the symbol with. The default is center.

The current context state defines the full drawing operation. For example, the current transformation and clip shapes affect how SwiftUI draws the symbol.
