Metron is a Swift library that extends CoreGraphics 2D geometric primitives with a comprehensive collection of geometric functions and types. It enables intuitive geometric calculations like circle containment tests, angle arithmetic, line segment intersections, and polygon operations.

Use cases

• check if a touch point is inside a circle in iOS
• add and normalize angles in radians and degrees
• find intersections between line segments and view frames
• rotate polygon points around an anchor point and build a CGPath
• compute convex hull of a set of points
• calculate distances and relative positions of points in a rect

When to choose

• you do 2D geometry or drawing math in Swift with CoreGraphics
• you want readable, expressive geometric calculations instead of manual trigonometry
• you need convenient extensions for CGPoint, CGVector, CGRect, and polygons

When to avoid

• you need 3D geometry or physics simulation
• your project is not in Swift or does not use CoreGraphics
• you need a library with recent releases or active maintenance
