• String length in Swift 1.2 and Swift 2.0 [duplicate] 5 answers

let newLength = countElements(textField.text) + countElements(string) - range.length;

When i'm running my app, it suddenly shows the error of unresolved identifier.

Answer 1

It appears you are attempting to use Swift 1.0 code in a later version of Swift. countElements was removed in iOS 8.3 (with Swift 1.2) -- you need to be logged in to see the release notes

in Swift 2.0, it is now str.characters.count
