See all parameter permutations in code completion in Xcode 15

Xcode 15 beta comes with some great improvements to code completion. One of my favorite is the ability to view all possible permutations of function parameters.

If a function contains more than one default parameter, we can see all the possible cases by pressing the right arrow keyboard key. This lets us choose the right permutation without any extra typing.
