let contextBuilder = LDContextBuilder(key: "EXAMPLE_CONTEXT_KEY")
guard case .success(let context) = contextBuilder.build()
else { return }

LDClient.start(config: config, context: context, startWaitSeconds: 5) { timedOut in
    if timedOut {
        print("SDK didn't initialize in 5 seconds.  SDK is still running and trying to get latest flags.")

    }
}

print("SDK started.")
