You can use the random method in Int struct for this.

let random:Int = Int.random(in: 1...5)

The above code will generate a random number within the closed range 1 to 5.

In closed range, both the numbers are inclusive.

let range = 1...5
print(range.contains(0)) // false
print(range.contains(3)) // true
print(range.contains(5)) // true
