Swift version: 5.6
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 }
