Is there a way to shorten if statements with arc4random_uniform( ) inside them?

Question

I am having some trouble with some if-statements. I am trying to figure out how to shorten if-statements with arc4random_uniform inside them. Here is my code:

func firstCustomNumberRange(sender : AnyObject){

    if (firstCustomNumberRangeLabel == 1 )
    {
        var randomNumber = 1
    }


    if (firstCustomNumberRangeLabel == 2 )
    {
        var randomNumber = arc4random_uniform( 2) + 1
    }


    if (firstCustomNumberRangeLabel == 3 )
    {
        var randomNumber = arc4random_uniform( 3) + 1
    }


    if (firstCustomNumberRangeLabel == 4 )
    {
        var randomNumber = arc4random_uniform( 4) + 1
    }
     ...}

(I repeated the pattern up to 20). This was a very time consuming process and it took me about 30 minutes just to write these simple if-statements.

Is it possible to shorten if statements with custom arc4random_uniform( ) inside them.

Thanks in advance.

Just pass the value of firstCustomNumberRangeLabel to arc4random_uniform() directly:

func firstCustomNumberRange(sender : AnyObject){
    if let numberRange = NSNumberFormatter().numberFromString(firstCustomNumberRangeLabel.text!) {
        let randomNumber = arc4random_uniform(UInt32(numberRange.unsignedIntegerValue)) + 1
    }
}
