Initializing the AppFlags SDK​

We suggest initializing the AppFlags SDK in the init of your App class or wherever your application initializes so that the SDK initializes as early as possible.

Client initialization​

Initialize AppFlagsClient as shown below:

init() {
    let user = AppFlagsUser(key: "user-xyz")
    let appFlagsClient = try? AppFlagsClient(
        sdkKey: "YOUR_SDK_KEY",
        user: user
    )
}
tip

You should only create one instance of AppFlagsClient. We suggest keeping your AppFlagsClient in a singleton class. See our examples.

User identification​

The iOS SDK requires an AppFlagsUser object to identify the user. This contains a userKey which is a unique string that identifies the user and does not change between sessions.

You can update the SDK with a new user if the user changes during the application lifecycle.
