How to find the first matching element in an array

Swift version: 5.0

Paul Hudson    @twostraws   

The first() method exists on all sequences, and returns the first item in a sequence that passes a test you specify.

For example, given the following array:

let scores = [80, 100, 80, 85]

We could write code to find the first score that was over 85:

let firstHigh = scores.first { $0 > 85 }
