Broken Xcode 16 Tab autocomplete

I've recently upgraded to Xcode 16 and noticed a change in how the Tab key functions during autocomplete.

Previously, pressing Tab would extend the typed text up to the first point of choice.

For example, we have two classes: NSViewController and NSViewCoordinator

BEFORE, typing: "NSV" + Tab used to complete to NSViewCo

Now, in Xcode 16, pressing Tab selects the first suggestion by default, instead of completing up to the choice point.

That is very inconvenient because very often I want just see all possible cases with some prefix...without need of typing all prefix manually.

How to restore the previous behavior?

Is there an option in settings to revert this, or perhaps a workaround to achieve the same effect?
