BarChartKit

UIKit / SwiftUI library for creating Bar Chart similar to chart used in iOS Health app.

Requirements

• iOS 13.0+
• watchOS 6.0+
• macOS 10.15+

Installation

BarChartKit supports XCFramework integration into Xcode project. Just go to Release page, download latest version, drag and drop it into existing Xcode project and you are done 🎉

BarChartKit also supports SwiftPM. You can integrate BarChartKit using SwiftPM directly via Xcode or manually using Package.swift.

Xcode

To add a package dependency to your Xcode project, select File > Swift Packages > Add Package Dependency and enter its repository URL. You can also navigate to your target’s General pane, and in the “Frameworks, Libraries, and Embedded Content” section, click the + button. In the “Choose frameworks and libraries to add” dialog, select Add Other, and choose Add Package Dependency.

Instead of adding a repository URL, you can search for a package on GitHub or GitHub Enterprise. Add your GitHub or GitHub Enterprise account in Xcode’s preferences, and a list of package repositories appears as you type. The following screenshot shows the list of repositories for the search term ExamplePackage.

Usage

UIKit

import BarChartKit

let mockBarChartDataSet: BarChartView.DataSet? = BarChartView.DataSet(elements: [
