Since SwiftUI uses UIkit and AppKit behind the scenes, this means that rendering isn’t any faster. However, in terms of development build time, SwiftUI usually performs better than UIkit. That’s because the hierarchy of view resides in value-type structs stored on the stack, which means no costly memory allocations.

Is SwiftUI open source?

Most of Apple’s frameworks are closed source and you cannot see more than these public headers. There are exceptions (like the Darwin kernel is open source), and the Swift language itself is open source, but the frameworks themselves (like SwiftUI) are closed.
