模拟器变成了Hello world

Question

I'm learning Swift, using some objects. but the simulator always turns white background and says hello world.

Answer 1

You set the design in the LaunchScreen which actually should be in Main.storyboard

Search for a file called "Main.storyboard" and set the design there

Answer 2

You are setting your design in your Launchscreen.storyboard . This is only shown when your apps launches.

You need to create your design on Main.storyboard instead.
