How to trim Array items in swift?

Question

my array looks like this:

myArray = [a (1), b (22), c (34), d (6)]

Is there any way i can get only the alphabets of the array like:

myTrimmedArray = [a, b, c, d]

If I can get each elemnts of arrray trim it and then append it in a new array also works fine for me. But is that possible?

Answer 1

var arrayCount = myArray.count
var i: Int
    for(i = 0; i < arrayCount; i++){
        var name = myArray[i] as String
        var myStringArr = name.componentsSeparatedByString(" ")
        var arrayValue = myStringArr[0]
        self.myTirimmedArray.append(arrayValue)   //Output: myTrimmedArray = [a, b, c, d]
    }   

In this instaed of componentsSeparatedByString I could use NSCharacterSet But this thing worked for my requirements
