Error: value of type 'String' has no member 'Generator' in Swift [duplicate]

Question

I have this piece of code in Swift:

var password = "Meet me in St. Louis"
for character in password {
    if character == "e" {
        print("found an e!")
    } else {
    }
}

which throws the following error: value of type 'String' has no member 'Generator' in Swift in line: for character in password

I have tried to find online the possible error, but I can't (plus I am new to Swift and trying to navigate myself through the idiosyncrasies of the language).

Any help would be much appreciated (plus a brief explanation of what I am missing if possible)

Answer 1

In order for your code to work you need to do this :

var password = "Meet me in St. Louis"
for character in password.characters {
    if character == "e" {
        print("found an e!")
    } else {
    }
}

The problem with your code not working was the fact that it was not iterating over your array looking for a particular Character. Changing it to password.characters forces i to "search" each Character of the array password and voila.This behaviour happens in swift 2.0 because String no longer conforms to SequenceType protocol while String.CharacterView does!
