How to find the minimum of three numbers
You can find the minimum of three numbers by using the min() function twice. This function takes either two integers or two floating-point numbers, but can't accept mixed types. Here's an example:
let first = 10
let second = 15
let third = 18
let smallest = min(min(first, second), third)Available from iOS 2.0
