The products that we build contain complex flows and highly interactive elements. As a result, there's so many important decisions that we need to make. SwiftUI helps by quickly surfacing all of those important details that need your attention, for example, how an image should look when it's loading or how a button appears when it's pressed. These are the types of things that make a product feel complete. They're easily hidden in static design tools but are quickly surfaced when working in a dynamic tool like SwiftUI.That's because SwiftUI makes it easy to build your designs on device. In doing this, you gain a more complete understanding of what you're making. Separate parts now interact together, and you can begin to evaluate the experience as a whole. This process quickly reveals what's working in your design and what still needs attention or polish. On Maps, we've found this to be tremendously helpful.

You can look at an interface and see it as a clearly signposted user journey you should follow. Or you can see it as a collection of functions and affordances to repurpose. As raw material, rather than a guided path.
