How to find the first matching element in an array
Swift version: 5.0
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 }LEARN SWIFTUI FOR FREE I wrote a massive, free SwiftUI tutorial collection, and also have a growing list of free SwiftUI tutorials on YouTube – get started today!
