SE-0207 provides a new allSatisfy()
method that checks whether all items in a sequence pass a condition.
For example, if we had an array of exam results like this:
let scores = [85, 88, 95, 92]
We could decide whether a student passed their course by checking whether all their exam results were 85 or higher:
let passed = scores.allSatisfy { $0 >= 85 }
