Latest release
1.0.1
Published September 5, 2026. Install version 1.0.1.
One familiar workflow
Save, read, update, then remove.
A KeychainPassword value identifies an item. set creates it or updates the existing match. Reads return nil when there is no item.
A generic password
import Lockbox
let password = KeychainPassword.generic(
service: "com.example.account",
account: "person@example.com"
)
try password.set(string: "a-secret")
let savedPassword = try password.getString()
try password.remove()Save and update one keychain record
The service and account identify the record. A later save replaces its secret.
| Field | STORED RECORD | UPDATED RECORD |
|---|---|---|
| service | com.example.app | com.example.app |
| account | ada@example.com | ada@example.com |
| secret | first-secret | replacement-secret |
