Sort Multidimensional array of specific class swift

Question

I have a class:

   class Rates{
var price:Double?
}

Multidimensional Array:

var rates:[[Rates]] = [[],[],[],[],[]]

I am trying to sort every array in rates from smallest Double to Largest. Here is what I tried

 for x in 0 ..< 4 {

      self.shippingRates[x].sort({ (Rates, Rates2) -> Bool in
                            return Rates.price < Rates2.price
                        })
                    }

But for some reason the sort isn't working, when i display the data it doesn't show up sorted. What am I doing wrong?

Edited the post, I had rates2.price in the code :/ still doesnt sort — Kashish Goel

Because sort returns a new array, which you didn't retain. Use sortInPlace instead:

for x in 0 ..< 4 {
    self.shippingRates[x].sortInPlace { $0.price < $1.price }
}
