Open Source Swift Libraries

An elegant modern declarative data visualization chart framework for iOS, iPadOS and macOS. Extremely powerful, supports line, spline, area, areaspline, column, bar, pie, scatter, angular gauges, arearange, areasplinerange, columnrange, bubble, box plot, error bars, funnel, waterfall and polar chart types. AAInfographics is the Swift language version of AAChartKit which is object-oriented, a set of easy-to-use, extremely elegant graphics drawing controls,based on the popular open source front-end chart library Highcharts. It makes it very fast to add interactive charts to your mobile projects. It supports single touch-drag for data inspection, multi-touch for zooming, and advanced responsiveness for your apps. Unlike previous imperative programming techniques, drawing any custom chart in AAChartKit, you don't need to care about the inner implementation details which is annoying && boring. Describe what you want, you will get what you described.

Starscream is a conforming WebSocket (RFC 6455) library in Swift. Once imported, you can open a connection to your WebSocket server. Note that socket is probably best as a property, so it doesn't get deallocated right after being setup. After you are connected, there is either a delegate or closure you can use for process WebSocket events. The writeData method gives you a simple way to send Data (binary) data to the server. The writeString method is the same as writeData, but sends text/string. The writePing method is the same as write, but sends a ping control frame. Starscream will automatically respond to incoming ping control frames so you do not need to manually send pongs. You can override the default websocket headers, add your own custom ones and set a timeout. Update docs on how to load certificates and public keys into an app bundle, use the builtin pinner and TrustKit.
