— Swift, Random, Boolean — 1 min read
In Swift, there are a few different ways to generate a random Boolean value. Here are three options:
Bool.random()
method:This method is part of the Swift standard library and returns a random Boolean value with equal probability of being true
or false
. To use it, simply call Bool.random()
, like this:
1let randomBool = Bool.random()
arc4random_uniform(_:)
function:This function is part of the Darwin
module, which provides access to many low-level functions and data types in the macOS and iOS operating systems. It generates a random unsigned integer value between 0
and a given upper bound.
To use this function to generate a random Boolean value, you can call arc4random_uniform(2)
and check whether the result is 0
or 1
. If the result is 0
, the Boolean value is false
, and if the result is 1
, the Boolean value is true
. Here's an example of how to use this function:
1import Darwin2
3let randomInt = arc4random_uniform(2)4let randomBool = randomInt == 1
Int.random(in:)
method:This method is part of the Swift standard library and returns a random integer value within a given range. To use it to generate a random Boolean value, you can call Int.random(in: 0..<2)
and check whether the result is 0
or 1
. If the result is 0
, the Boolean value is false
, and if the result is 1
, the Boolean value is true
. Here's an example of how to use this method:
1let randomInt = Int.random(in: 0..<2)2let randomBool = randomInt == 1
These are just a few options for generating a random Boolean value in Swift. Which one you choose will depend on your specific needs and preferences. Regardless of which method you choose, generating a random Boolean value in Swift is a quick and easy task.
