The look canvas the thing is isn’t just an approximation of your user interface — it’s your Stay application. And Xcode can swap edited code straight in the Dwell app working with dynamic substitution.

In the preview you’ll see a large black circle fills the out there monitor width. That’s a get started, however it’s not very suitable – we wish some colour in there, and ideally incorporating a little bit House on both aspect so it doesn’t glance so restricted.
