Swift Charts - Beyond the basics

on YouTube ↗22m

" summary

Prototype Apple Watch app reads seven days of steps from HealthKit and renders them as a vertical BarMark + RuleMark chart with three RuleMarks: per-day highlight navigable via digitalCrownRotation, a user-set goal line, and a 7-day average. Examples show customizing axis labels, forcing a Y scale domain, centering weekday X labels, gradients and opacity, and combining marks; code is demoed and intended for GitHub. Requires Xcode 14 and iOS 16+ / watchOS 9+ and SwiftUI-only.
