It would be useful if sizeThatFits would drive the selectable mode in preview (as it was working in previous Xcode versions). It is now very annoying to have previews always start in live mode, with bezels. Our screens have previews both "as presented" and "full content only" and this makes it hard to distinguish the intent of preview.

We have a similar use case. Previously, we were able to force the selectable mode using sizeThatFits layout and it worked great. Now, this is being ignored and all our previews start in live mode. But for inspecting the component and interactive work, we would like to force some previews to be in selectable mode. Either by respecting the sizeThatFits layout modifier (if present -> use selectable mode) or by introducing a new modifier such as previewMode(.live/.selectable).
