One more heads up: As Swift evolves, if you are not using the latest Swift compiler, you shouldn’t check out the master branch. Instead, you should go to the release page and pick up whatever suits you.

• Xcode 14 / Swift 5.7 (master branch)
• iOS >= 12.0 (Use as an Embedded Framework)
• tvOS >= 12.0
• macOS >= 10.13

Okay so there’s this beautiful library called MPAndroidChart by Philipp Jahoda which has become very popular amongst Android developers, but there was no decent solution to create charts for iOS.

I’ve chosen to write it in Swift as it can be highly optimized by the compiler, and can be used in both Swift and ObjC project. The demo project is written in ObjC to demonstrate how it works.

An amazing feature of this library now, for Android, iOS, tvOS and macOS, is the time it saves you when developing for both platforms, as the learning curve is singleton- it happens only once, and the code stays very similar so developers don’t have to go around and re-invent the app to produce the same output with a different library. (And that’s not even considering the fact that there’s not really another good choice out there currently…)

Documentation

Currently there’s no need for documentation for the iOS/tvOS/macOS version, as the API is 95% the same as on Android.
You can read the official MPAndroidChart documentation here: Wiki

Or you can see the Charts Demo project in both Objective-C and Swift (ChartsDemo-iOS, as well as macOS ChartsDemo-macOS) and learn the how-tos from it.
