The first release of TradingChart — a native SwiftUI trading chart for iOS built on Swift Charts.

Highlights

  • Styles: line, area and candlesticks, switchable at runtime, with an optional on-chart style picker.
  • Indicators: SMA, EMA, WMA, Bollinger Bands (overlays) and Volume, RSI, MACD (panes that scroll with the price), verified against TA-Lib. Add your own with the ChartIndicator protocol, toggle them with the Binance-style IndicatorBar.
  • Interaction: inertial one-finger scrolling, pinch zoom, long-press crosshair with an OHLC tooltip, a smooth price axis that follows the visible bars on every frame, high/low markers and a current-price badge on the axis.
  • Live data and history: candle or tick updates with an interval gate, a sticky live edge, and history paging (approachedHistoryStart + prependHistory) without jumps.
  • Drawing tools: horizontal line, trend line and ray — create, select, drag, delete; Codable drawings; custom tools through DrawingTool.
  • Customization: themes, price/time formatters, configuration, VoiceOver support and localization into 14 languages (including Arabic).

Requirements

  • Chart UI: iOS 17+. TradingChartCore / TradingChartIndicators: iOS 16+ — the package can be added to apps that target iOS 16 (gate the chart with if #available(iOS 17, *)).
  • Swift 6, Xcode 16 or later.
