Discussion
Use this method to generate an integer within a specific range when you are using a custom random number generator. This example creates three new values in the range 1..<100.
for _ in 1...3 {
print(Int.random(in: 1..<100, using: &myGenerator))
}
// Prints "7"
// Prints "44"
// Prints "21"
