adamwulf/PerformanceBezier
A small library to dramatically speed up common operations on UIBezierPath, and also bring its functionality closer to NSBezierPath
.package(url: "https://github.com/adamwulf/PerformanceBezier.git", from: "1.3.0")

iOS UIBezierPath Performance

This code dramatically improves performance for common UIBezierPath operations, and it also brings UIBezierPath API closer to its NSBezierPath counterpart. For full background of this repo, checkout the blogpost explaining what this framework does.

This code was originally part of Loose Leaf. Additional components and libraries from the app have also been open sourced.

Available as a Swift Package!

Install PerformanceBezier in your project through Swift Package Manager as of v1.3.0!

What is this?

This framework adds caching into every UIBezierPath so that common operations can be performed in constant time. It also adds some missing NSBezierPath methods to the UIBezierPath class.

After linking this framework into your project, all Bezier paths will automatically be upgraded to use this new caching. No custom UIBezierPath allocation or initialization is required.

For example, by default there is no O(1) way to retrieve elements from a UIBezierPath. In order to retrieve the first point of the curve, you must CGPathApply() and interate over the entire path to retrieve that single point. This framework changes that. For many algorithms, this can dramatically affect performance.

Are you using PerformanceBezier?

Let me know! I'd love to know where PerformanceBezier is using and how it's affecting your apps. Ping me at @adamwulf!

Also - If you like PerformanceBezier, then you'll love ClippingBezier - an easy way to find intersecting points, lines, and shapes between two UIBezierPaths.
