Swift convert UInt to Int

Question

I have this expression which returns a UInt32:

let randomLetterNumber = arc4random()%26

I want to be able to use the number in

Answer 1

Just create a new int with it

let newRandom: Int = Int(randomLetterNumber)
if letters.count > newRandom {
    var randomLetter = letters[newRandom]
}

or if you never care about the UInt32 you can just create an Int immediately:

let randomLetterNumber = Int(arc4random() % 26)

Answer 2

More simple than this, impossible:

Int(myUInteger)

Answer 3

Int(arc4random_uniform(26)) does two things, one it eliminates the negative results from your current method and second should correctly creat an Int from the result.

Answer 4

You can do

let u: UInt32 = 0x1234abcd
let s: Int32 = Int32(bitPattern: u)
