Storyboard: How do I change the iOS version to see layout changes?

My app is made for iOS 12.4, so I usually use the iPhone SE 12.4 simulator (Xcode 12.4).

Switching to the iPhone SE 2 simulator (iOS 14.4) temporarily I noticed that the date/time pickers now look completely different:
They used to be simple scroll wheels but now you have to tap on the element to open the actual picker. The date picker now also opens an actual calendar, which I'm not a fan of because it's tedious to change the year that way.

How do I make the storyboard reflect these changes, so I can make everything fit again? I remember that there was a way to simply set the iOS version for it (without changing the deployment info for the whole project) but now that I'm looking for it I can't find it of course.

They used to be simple scroll wheels 

If you select the picker in IB and look at Attributes Inspector, you can select Wheels for preferred style instead of Automatic.

That will give you the style you were accustomed with.

To select another iOS version in simulator, just select the appropriate simulator.
In Xcode, I think you have to return to an older version of Xcode.
You can still select wheels in iOS 14? That's good to know, thanks!

If I select one of the pickers in storyboard, then there's a "Builds For" option in the inspector. Changing that from "Deployment Target (12.2)" to e.g. "iOS 14.0 and Later" doesn't change anything though, the pickers still look like the old wheels and if I then start an iOS 14 simulator (like the iPhone SE2), the pickers look like the new "click me" ones.

I know that there was a way to make the UI elements in storyboard change their look according to the version you pick but I can't seem to find that setting anymore.
