Seeded random numbers with upper bound in Swift 3?

Question

Is there any way to seed the random number generator and also specify an upper bound in Swift 3?

Answer 1

The most convenient random number generators in Swift reside in GameKit. This generates random integers between -10 and 10 (inclusive):

import GameKit
let source = GKARC4RandomSource(seed: Data(bytes: [42]))
let random = GKRandomDistribution(randomSource: source, lowestValue: -10, highestValue: 10)

for _ in 0..<10 {
    print(random.nextInt())
}
