Replace value on index in array

Question

I have a array:

[h,e,l,l,o]

And i want to replace an value on the index, for example i want to change the first l at index 2. I know the index so that is not a problem, the only problem is to replace that value.

How can i do this?

Answer 1

As mentionned here https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/CollectionTypes.html

You can modify your array like that:

var array = ["h", "e", "l", "l", "o"]
array[2] = "Six eggs"

Answer 2

the insert function will add a new value to the array, what you need to do is simply

var newCharacter = "a"

arr[2] = newCharacter
