Core Graphics vs SwiftUI Canvas

Developers should learn Core Graphics when they need to create custom, high-performance graphics that aren't possible with standard UI components, such as dynamic charts, custom animations, or image processing meets developers should use swiftui canvas when building ios, macos, watchos, or tvos apps with swiftui to accelerate ui development and improve productivity. Here's our take.

Core Graphics

Nice Pick

Developers should learn Core Graphics when they need to create custom, high-performance graphics that aren't possible with standard UI components, such as dynamic charts, custom animations, or image processing

Pros

• It's essential for building advanced visual features in apps where pixel-perfect control is required, like drawing tools, data visualization, or game development
• Related to: swift, objective-c

Cons

• Specific tradeoffs depend on your use case

SwiftUI Canvas

Developers should use SwiftUI Canvas when building iOS, macOS, watchOS, or tvOS apps with SwiftUI to accelerate UI development and improve productivity

Pros

• It is particularly valuable for rapid prototyping, iterative design changes, and learning SwiftUI, as it eliminates the compile-run cycle for visual feedback
• Related to: swiftui, xcode

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Core Graphics is a framework while SwiftUI Canvas is a tool. We picked Core Graphics based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Core Graphics wins

Based on overall popularity. Core Graphics is more widely used, but SwiftUI Canvas excels in its own space.
