Declaration

static func random(in range: ClosedRange<Self>) -> Self

Parameters

• range:

  The range in which to create a random value.

Return Value

A random value within the bounds of range.

Discussion

Use this method to generate an integer within a specific range. This example creates three new values in the range 1...100.

for _ in 1...3 {
    print(Int.random(in: 1...100))
}
// Prints "53"
// Prints "64"
// Prints "5"

This method is equivalent to calling random(in:using:), passing in the system’s default random generator.
