Create dynamic array of size swift

Question

I want to create an array if I do this how it works:

var arrayEingabe = Array(count:30, repeatedValue:0)

If I do like this, it doesn't work:

var sizeArray = 30
var arrayEingabe = Array(count:sizeArray, repeatedValue:0)

In the end, I want to resize my array based on what the user has entered.

I searched the internet for one hour, but I couldn't find an answer.

Thanks for the help guys

Actually both examples compiled well for me, but you should be more type specific. Something like:

var arrayCount:Int = 30
var arrayEingabe = Array(count:arrayCount, repeatedValue:Int())

in fact this might be better for you:

var arrayEingabe = [Int]()

This creates an empty array, and as mentioned in the comments, Swift arrays are mutable. You can add, replace and remove items as you like.

In Swift 3.0.2: - You can use array initialization method below: -

override init(){
let array = Array(repeating:-1, count:6)
}

Here, repeating: is the default for the array. count: - the number of arrays.
