In iOS 18, Swift Charts introduces several new features and improvements:
-
Function Plots: Swift Charts now allows you to visualize mathematical functions in your apps. This includes:
- Line Plot: For visualizing a single function.
- Area Plot: To fill in the area between two functions.
- Parametric Functions: You can graph parametric functions where x and y are defined in terms of a third variable, t.
- Piecewise Functions: Swift Charts can handle piecewise functions, including cases where certain values in the domain do not have an output.
-
Vectorized Plotting APIs: These new APIs support visualizing larger datasets more efficiently, making your charts more performant.
-
Accessibility: Swift Charts ensures that data visualizations are accessible by default, including support for VoiceOver to describe the chart.
For a detailed walkthrough of these new features, you can watch the session Swift Charts: Vectorized and function plots starting at 00:12:37.
