Whats wrong?

This gives me an error, whats wrong ?

my code:

import Foundation

// This is my factbook where all the facts on the app are stored.

struct factBook {

let factArray = [
"Pteronophobia is the fear of being tickled by feathers!",
"In Sweden, it is illegal to name a child superman and ikea.",
"The average woman uses her height in lipstick every 5 years.",
"During your lifetime, you will produce enough saliva to fill two swimming pools.",
"If you consistently fart for 6 years & 9 months, enough gas is produced to create the energy of an atomic bomb!",
"King Henry VIII slept with a gigantic axe beside him.",
]
    func randomFact() -> String{
        var randomNumber = Int(arc4random_uniform(factArray.count))
    }

}

Hi Nils

The problem is, that you are trying to convert the result to an Int when the type is actually UInt32. To fix this simply write UInt32 instead and write it after the arc4random function. Then keep the Int to convert the output to Int instead of the UInt32 like this:

struct factBook {

    let factArray = [
        "Pteronophobia is the fear of being tickled by feathers!",
        "In Sweden, it is illegal to name a child superman and ikea.",
        "The average woman uses her height in lipstick every 5 years.",
        "During your lifetime, you will produce enough saliva to fill two swimming pools.",
        "If you consistently fart for 6 years & 9 months, enough gas is produced to create the energy of an atomic bomb!",
        "King Henry VIII slept with a gigantic axe beside him.",
    ]
    func randomFact() -> String{
        var randomNumber = Int(arc4random_uniform(UInt32(factArray.count)))
    }

}

You will of course also need to add a return statement.

I hope that helps :-)
