I have successfully completed iPhone development using Auto Layout.
Thanks to Auto Layout, UI is displayed normally on all iPhones.
However, if I run it on the iPad, the UI will not break, but the screen will be small.
I have no idea what to do to support iPad size in storyboard or build settings.
If I want my app to respond to iPad size, what method should I use specifically?
I am using Xcode 10 and Swift 4.
Select your project in Xcode, then use the General tab. It's under the sections on Identity and Signing.
