breakpoint Int

Hello Thomas :

Would you mind if you show your code ? This way I can help you better.

  struct FactBook {
    let factsArray = ["Array with 10 things in it"]

    func randomFact() -> String {
      let unsignedArrayCount = factsArray.count
      let unsignedRandomNumber = arc4random_uniform(UInt32(unsignedArrayCount))
      let randomNumber = Int(unsignedRandomNumber)
      return factsArray[randomNumber]
    }
  }

This is what it looks like. Like I said the breakpoint error says unsignedArrayCount = 10, unsignedRandomNumber = {8}, and randomNumber = 140734746147408. Not sure what is going on here

Everything looks fine to me, but try this and see how it behaves. It shouldn't behave any different, since it's basically the same thing. But it's worth giving it a try.

struct FactBook {
    let factsArray = ["Array with 10 things in it"]

    func randomFact() -> String {
        let unsignedArrayCount = UInt32(factsArray.count)
        let unsignedRandomNumber = arc4random_uniform(unsignedArrayCount)
        let randomNumber = Int(unsignedRandomNumber)

        return factsArray[randomNumber]
    }
}

If that does not work let me know, and we can look deeper into it.

I used your code in my sample of the same app, and it worked perfectly.

I changed the code to what you said and it still didn't work. But I decided to just start over and make a new projects and now it seems to work the only difference from my last one is I changed the type of phone to used in the simulator. The video says to use iPhone 5 but I used iPhone 6s. I don't know what happened but it works. Thanks a lot Jhoan.
