Both equally of those can be achieved by contacting methods about the Circle perspective. We get in touch with these perspective modifiers

The look canvas you see isn’t just an approximation of your consumer interface — it’s your live app. And Xcode can swap edited code directly with your Are living app applying dynamic alternative.
