xcode模拟器为什么不显示全屏

Question

I upgraded my xcode to version 12.3 and now when I create a new project, the simulator does not show full screen. The old projects however, does show simulator in full screen.

I checked this (very old) question and it says to add a certain file, how can I do that?

Answer 1

In my case I removed launchScreen, and then added it back

So, to add launch screen if u accidentally removed it,

Press cmd + n

This is allow you to add new launch screen

Then in the general tab under

App Icons and Launch Images

Set your launch screen file

also in the deployment Info set

Main interface

Answer 2

open the project in Xcode -> select Target -> General -> add Launch screen in Launch Screen File

Answer 3

In the Info.plist file add key: Launch screen interface file base name and value: LaunchScreen
