AppPear/ChartView

SwiftUICharts is a Swift Package Manager library that provides a composable, SwiftUI-native framework for rendering interactive data visualizations. It supports multiple chart types, including line, bar, pie, and activity rings, with features for real-time streaming data, performance optimization, and accessibility. The system is designed for iOS, macOS, and watchOS, offering a unified API for styling, interaction handling, and axis configuration.

5 changes.

The project transitioned to Swift Package Manager by adding workspace and scheme configurations, while upgrading to Swift 5.3 and expanding platform support. It also implemented Apple privacy manifest compliance and added comprehensive unit and smoke tests to ensure library stability and correct rendering.

7 changes.

The project was rebuilt on a composable, value-based SwiftUI architecture, replacing the previous protocol-based system with a new foundation driven by environment and preference keys. This period saw the introduction of core chart components including LineChart, BarChart, PieChart, and RingsChart, each featuring interactive selection, accessibility support, and performance optimizations like downsampling. A showcase application was also added to demonstrate the library's capabilities, such as real-time streaming data and dynamic axis configuration.

Introduces a new RingsChart component that renders concentric activity rings, supporting multiple series with gradient fills, drop shadows, and interactive touch handling. Users can now display circular progress indicators with accessibility labels and selection events driven by drag gestures.

The project now includes the standard Swift Package Manager workspace files (contents.xcworkspacedata and IDEWorkspaceChecks.plist). This enables developers to open the package directly in Xcode as a workspace, facilitating easier debugging, testing, and integration of the library within Xcode-based projects.

This change introduces the first implementations of the LineChart, PieChart, and BarChart views, establishing the core rendering and interaction capabilities for the library. The LineChart supports curved or straight line styles, animated drawing, background gradients, and interactive point selection via drag gestures that publish selection events. The PieChart renders data as proportional slices with spring animations, touch interaction to highlight slices, and accessibility labels. Both chart types integrate with the existing environment-based configuration system (styles, series visibility, and selection handlers) and include preview providers for SwiftUI Canvas.

This change introduces the BarChart view, a new SwiftUI component that renders bar charts using a composable structure (BarChart, BarChartRow, BarChartCell). Users can now visualize data series with support for negative values, which are rendered below the baseline. The component includes interactive features, allowing users to drag across the chart to select specific bars, which triggers selection events via a dispatcher. It also respects series visibility configurations and provides accessibility labels for each bar.

A new iOS example application, \SwiftUIChartsShowcase\, has been added to the Examples directory to demonstrate the library's composable API. The app features a tab-based interface with a main showcase view and a dynamic data lab. It illustrates various charting capabilities including line, bar, pie, and rings charts, along with advanced features such as auto-axis tick generation with collision handling, high-contrast accessibility presets, performance mode with line downsampling for large datasets, and interactive elements like drag selection callbacks and legend-driven series visibility controls.

The SwiftUICharts SDK now includes a PrivacyInfo.xcprivacy file declaring that it does not track users, collect data, or access restricted APIs, ensuring compliance with Apple's privacy requirements. Additionally, a placeholder source file containing a generic 'Hello, World!' struct has been removed from the distribution.

The project now includes an Xcode scheme management file that defines shared schemes for the main SwiftUICharts target and its associated tests, setting them as primary buildables and establishing their order hint. This configuration supports the switch to the Swift Package Manager by providing the necessary IDE-level build settings for the library and its test suite.

The charting library has been rebuilt on a new SwiftUI-native foundation, replacing the previous protocol-based \ChartBase\ with a composable system driven by environment and preference keys. This change introduces a new \ChartData\ value model for managing data points and ranges, a \ChartAxisConfig\ for unified axis styling and label positioning, and a \ChartGridConfig\ for grid customization. Users gain access to new capabilities including a \ChartStreamingDataSource\ for real-time data with windowed auto-scroll, a \ChartDownsampler\ for performance optimization on large datasets, and a callback-based \ChartSelectionHandler\ for interaction events. The visual layer now uses a \CardView\ wrapper with configurable shadows and a \ChartLegend\ that allows users to toggle series visibility directly.

Added a comprehensive suite of tests for the SwiftUICharts library, including unit tests for array rotation logic, CGPoint step calculations, hex color parsing, and the chart selection dispatcher. Smoke tests verify that composable chart views (Bar, Pie, Rings, Line) render correctly with optional interaction values, shared chart values, and mixed series. Additional tests cover X-axis alignment and normalization logic, auto-tick and label rotation modifiers, high-contrast style presets, performance mode modifiers, and streaming data sources. Documentation integrity and migration guide tests ensure that example files, resources, and migration mappings for removed public types are present and correctly referenced.

Tests · high confidence

The package manifest has been updated to require Swift tools version 5.3, enabling the use of newer language features. Platform support is now explicitly defined for iOS 13, watchOS 6, and macOS 10.15, ensuring compatibility with these operating systems. Additionally, a privacy manifest file (PrivacyInfo.xcprivacy) is now included as a resource in the main target to comply with Apple's privacy requirements.
