Usage

Basic Usage

To start using Locksmith, import it in your code:

import Locksmith

After importing Locksmith, you can begin using its features such as:

  • Storing and retrieving data

Keychain Access Group

If you want to share data between multiple apps or extensions, you need to set up a Keychain Access Group. To configure your Keychain Access Group:

  1. In Xcode, select your project in the Project Navigator.
  2. Go to the “Target” settings for your primary target.
  3. Under “Signing & Capabilities”, add the “Keychain Sharing” capability.
  4. In the “Keychain Groups” section, add your Keychain Access Group identifier.

Error Handling

Locksmith provides robust error handling. When calling methods, you can use Swift’s do-catch statement to handle any errors that occur:

do {
   try // Perform an operation with Locksmith
} catch let error as LocksmithError {
   // Handle Locksmith specific errors
} catch let error {
   // Handle other errors
}

Examples

Basic Example

Here is an example of storing and retrieving data with Locksmith:

import Locksmith

// Store data in the keychain
do {
   try Locksmith.saveData(data: ["password": "mySecretPassword"], forUserAccount: "myUserAccount")
} catch let error as LocksmithError {
   print("Error saving data: \\(error)")
}

// Retrieve data from the keychain
if let data = Locksmith.loadDataForUserAccount(userAccount: "myUserAccount") {
   print("Retrieved data: \\(data)")
} else {
   print("No data found")
}
