How to generate random floating point numbers in Swift

Answer 1

import Foundation

func generateRandomNumbers(count: Int, lower: Double, upper: Double) -> [Double] {
    return (0..<count).map { _ in Double.random(in: lower...upper) }
}

let count = 10
let lower = 0.0
let upper = 3.0

let randomNumbers = generateRandomNumbers(count: count, lower: lower, upper: upper)

for num in randomNumbers {
    print(String(format: "%.6f", num), terminator: " ")
}
