SecureStoreQueryable forces the implementer to provide a query property defined as a dictionary typed as.
SecureStoreError.swift: Contains an enum, which represents all the possible errors your wrapper can deal with.The code of your wrapper lives in the SecureStore group folder: The structure of your project should look like this: To keep you focused, the starter project has everything related to implementing your wrapper already set up for you. Once you’ve downloaded it, open SecureStore.xcodeproj in Xcode. Start by downloading the starter project using the Download Materials button at the top or bottom of this tutorial. Getting Startedįor this tutorial, you’ll use SecureStore, a boilerplate iOS framework where you’ll implement your Keychain Services API. Furthermore, you’ll provide unit tests to verify that your code works as you expect.
In particular, you’ll learn how to add, modify, delete and search for both generic and internet passwords. In this tutorial, you’ll delve deep into Keychain Services API and learn how to create your own wrapper, developing it as an iOS framework. Apple even offers one called GenericKeychain to make your life easier.Īlthough you can easily use third-party wrappers to interface with the unfriendly API that Apple provides, understanding Keychain Services adds a valuable tool to your developer tool belt. There are different Swift wrappers that allow you to interact with Keychain.
You have to use the Security framework, which is written mostly in C. It’s complicated to interact with Keychain directly, especially in Swift. Using Keychain is the best way to store small pieces of data that are critical to your app, like secrets and passwords.
One of the most important security elements for Apple developers is the iOS Keychain, a specialized database for storing metadata and sensitive information.
