SwiftUI 4 Charts Framework Practice Exam

SwiftUI 4 Charts Framework Practice Exam

SwiftUI 4 Charts Framework is a tool created by Apple that makes it easy to add beautiful charts and graphs to iPhone, iPad, and Mac apps. It helps developers show data visually—like bar charts, line graphs, or pie charts—so users can understand numbers and trends at a glance. With SwiftUI, everything is done using simple and clean code, which saves time and effort.

This framework is perfect for apps that need to display statistics, progress, or any kind of data in a clear and interactive way. Whether it's tracking steps, showing sales numbers, or visualizing health data, SwiftUI 4 Charts lets developers create rich and modern chart experiences without needing to build everything from scratch.
