RemoveAtIndex crash from swift array

Question

I have an array of letters, and want to match the characters against the letters and then do something to that letter (in this case turn it yellow) and then remove that matched

Answer 1

May i suggest a different approach where instead of removing from the initial array you make a new one, from which you can exclude the characters you don't want to appear in your array in the first place.

PS: keep in mind the following code works with Swift 2.0 Xcode 7 beta 6

var letters : [Character] = ["a","b", "c"]

var lettersToBeRemoved : [Character] = ["a"]

var newLetters : [Character] = []

for i in letters
{
    for j in lettersToBeRemoved
    {
        if i == j
        {
            continue
        }
            newLetters.append(i)
    }

}
print(newLetters)
