I realize the Swift book provided an implementation of a random number generator. Is the best practice to copy and paste this implementation in one's own program? Or is there a library that does this that we can use now?

To generate a random number in Swift, use Int. random() function. Int. random() returns a number, that is randomly selected, in the given range.
Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated.
In Swift, we can get a random element from an array by using randomELement() . If the array is empty, nil is returned.
Swift 4.2+
Swift 4.2 shipped with Xcode 10 introduces new easy-to-use random functions for many data types. You can call the random() method on numeric types.
let randomInt = Int.random(in: 0..<6) let randomDouble = Double.random(in: 2.71828...3.14159) let randomBool = Bool.random() If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
