using System;

class Program {
    static void Main() {
        int n = 10, a = 0, b = 1;
        for (int i = 0; i < n; i++) {
            Console.WriteLine(a);
            int temp = a;
            a = b;
            b = temp + b;
        }
    }
}

Fibonacci in Swift

func fibonacci(_ n: Int) {
    var a = 0, b = 1
    for _ in 0..<n {
        print(a)
        let temp = a
        a = b
        b = temp + b
    }
}
