Hi @ThinkHattke, there is no way to check if a key exist with this library. However, you can check if there is non-nil value saved for your key:

let keychain = KeychainSwift()
let value = keychain.get("my key")

if value == nil {
   print("No value")
}

Hi @evgenyneu, thanks for the solution, But it throws an error while building the app, but then I figured out a way.

`let keychain = KeychainSwift()

let logged = keychain.getBool("logged") ?? false`

This provided me the values without modifying any dataType.
