AnyObject makes me nervous (Can't find an initialiser for type...)

Making default index = 0 

    let defaults = NSUserDefaults.standardUserDefaults()

    if !(defaults.objectForKey("LastIndex") != nil)
    {
        defaults.setObject(Int(0), forKey: "LastIndex")
    }

Then trying to compare this index with random number

    var randomIndex: Int = 0
    let defaults = NSUserDefaults.standardUserDefaults()
    let lastIndex: Int = Int(defaults.objectForKey("LastIndex"))

    while randomIndex != lastIndex
    {
        randomIndex = Int(arc4random_uniform(UInt32(phrasesArray.count)))
    }

but getting an error enter image description here

If you want to store Int int NSUserDefaults you can do it directly this way:

NSUserDefaults.standardUserDefaults().setInteger(YourIntValue, forKey: "LastIndex")

Let me correct some of your code. First of all look at this code:

let defaults = NSUserDefaults.standardUserDefaults()

if !(defaults.objectForKey("LastIndex") != nil)
{
    defaults.setObject(Int(0), forKey: "LastIndex")
}

You are checking here that if there is value available for LastIndex or not but instead of trying that you can directly create a Int value with can directly read as Int from your memory with this code:

let abc = NSUserDefaults.standardUserDefaults().integerForKey("LastIndex")
println(abc)

With this code if there is no value for key LastIndex then it will set to 0 by default so it will print always 0 if there is nothing so you don't need to check if it is nil or not.

Now look at this code:

let lastIndex: Int = Int(defaults.objectForKey("LastIndex"))

Here you are reading values from that key where you are trying to casting it as Int but If you do it as I suggested you can directly get Int value form it so just make it simple like:

let lastIndex = NSUserDefaults.standardUserDefaults().integerForKey("LastIndex")

This will always return Int and if there is nothing set then it will be 0 by default.

And you can perform your action as you want:

while randomIndex != lastIndex {
        randomIndex = Int(arc4random_uniform(UInt32(phrasesArray.count)))
}

Hope it will help you.

I found the solution – so simple that i even LOL'ed. 

let lastIndex: Int = defaults.integerForKey("LastIndex")
