random(in:)

Returns a random value within the specified range.

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

Parameters

range: The range in which to create a random value. range must not be empty.

A random value within the bounds of range.

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 the version that takes a generator, passing in the system’s default random generator.
