Please explain the following problem in detail and provide code in Swift:
You are given an integer array `nums` and an integer `k`. Find the **largest even sum** of any subsequence of `nums` that has a length of `k`.
Return _this sum, or_ `-1` _if such a sum does not exist_.
A **subsequence** is an array that can be ... | dolphin | [
