Tap Settings > Network & internet > Airplane Mode to toggle it on or off. Swipe down from your home screen and tap Airplane Mode to switch it on or off. Airplane Mode disables all connections, but you can enable Wi-Fi while keeping cellular data disabled.

It is not possible to do this with the public APIs, which means that Apple won't approve an app for the App Store that does this.

Of course, you generally shouldn't do this anyway. I'm curious to hear the reason you had in mind.
