Fuzzy String Search in Swift

FuzzySearch.swift

func fuzzySearch(var originalString: String, var stringToSearch: String, caseSensitive: Bool = false)->Bool {

    if countElements(originalString)==0 || countElements(stringToSearch)==0 {
        return false
    }

    if countElements(originalString) < countElements(stringToSearch) {
        return false
    }

    if !caseSensitive {
        originalString = originalString.lowercaseString
        stringToSearch = stringToSearch.lowercaseString
    }

    var searchIndex : Int = 0

    for charOut in originalString{
        for (indexIn,charIn) in enumerate(stringToSearch) {
            if indexIn==searchIndex{
                if charOut==charIn{
                    searchIndex++
                    if searchIndex==countElements(stringToSearch) {
                        return true;
                    }
                    else {
                        break
                    }
                }
                else {
                    break
                }

            }
        }
    }
    return false;
}

//
var myTestString = "NSNumberFormatterPadPosition"

//Examples
fuzzySearch(myTestString,"NSNumber") //true
fuzzySearch(myTestString,"NSNumFormPaPos") //true
fuzzySearch(myTestString,"NSXNumber") //false

fuzzySearch(myTestString,"nsnumb") // false
fuzzySearch(myTestString,"nsnumb", caseSensitive:true) // true

Shouldn't the block for caseSensitive be

if !caseSensitive {
    originalString = originalString.lowercaseString;
    stringToSearch = stringToSearch.lowercaseString;
}

Fixed, thanks!
