I'm stuck here

We just learned the ins and outs of arrays, so let's put that knowledge into practice. Start by declaring a new array of Ints with six numbers as values. Assign this array to a variable named arrayOfInts.

// Enter your code below
var arrayOfInts: [String] = ["1", "2", "3", "4", "5", "6",]

Hi there! You're close! You filled up your array with the string form of numbers. The array should be of type [Int]. Remember, that we put string literals in quotes and numbers don't get quotes. Take a look at an example:

var x: Int = 7
var y: String = "7"

The variable x contains the integer 7. The variable y contains the string "7". Also, you have a trailing comma at the end of your array which is not needed.

I think you can get it with these hints, but let me know if you're still stuck! :sparkles:
