How do I feature flag UI elements by remote config in Swift?

In Swift, you can use remote config to implement feature flags for UI elements, allowing you to control the display and functionality of components in your app remotely. Below is a simple example of how to achieve this using Firebase Remote Config.

// Import Firebase Remote Config import Firebase // Assuming Firebase is already configured let remoteConfig = RemoteConfig.remoteConfig() // Fetch configuration from Firebase func fetchRemoteConfig() { remoteConfig.fetch { (status, error) in if status == .success { self.remoteConfig.activateFetched() self.updateUI() } else { print("Error fetching remote config: \(error?.localizedDescription ?? "No error available.")") } } } // Update UI based on the feature flag func updateUI() { let featureEnabled = remoteConfig["feature_name"].boolValue if featureEnabled { // Show the UI element yourFeatureUIElement.isHidden = false } else { // Hide the UI element yourFeatureUIElement.isHidden = true } }
