Iterate through alphabet in Swift

Question

in Obj-C it was possible to iterate through alphabet with:

for (char x=\'A\'; x<=\'Z\'; x++) {

In Swift this isn\'t possible. Any idea h

Answer 1

Updated for Swift 3.0 and higher

let startChar = Unicode.Scalar("A").value
let endChar = Unicode.Scalar("Z").value

for alphabet in startChar...endChar {

    if let char = Unicode.Scalar(alphabet) {

        print(char)
    }
}
