Does it help with chart accessibility and responsiveness?

Yes, it includes best practices for avoiding fixed heights that break Dynamic Type and ensures that scales are used honestly to provide accurate data representation.

Does this skill support the latest iOS 18 features?

Yes, it includes comprehensive patterns for iOS 18 vectorized plots like BarPlot and LinePlot, which are optimized for rendering large datasets.

How does this skill handle large datasets?

It guides you away from individual mark views for large data and toward vectorized plots (iOS 18+) to ensure the main thread remains responsive even with 10,000+ points.

Can I use this to create interactive charts?

Absolutely. The skill provides implementation details for iOS 17+ selection APIs, including point, range, and angular selection for interactive data exploration.

Mobile Development

Implements and optimizes sophisticated data visualizations using the Swift Charts framework for iOS applications.

This skill provides expert guidance for building high-performance, accessible, and interactive charts within SwiftUI. It covers the full spectrum of Swift Charts capabilities, from basic mark types like bars and lines to advanced iOS 17 and 18 features such as scrollable axes, interactive selection patterns, and vectorized plots for massive datasets. By following established patterns for scaling, custom axes, and legend configuration, this skill helps developers build production-grade dashboards, health trackers, and financial apps that respect Dynamic Type and modern Apple design standards.
