// Setup app group in your Xcode project // 1. Go to your project settings // 2. Click on the target of your main app // 3. Under "Signing & Capabilities," add an "App Group" // 4. Create a new app group (e.g., group.com.yourcompany.yourapp) // Shared UserDefaults let sharedDefaults = UserDefaults(suiteName: "group.com.yourcompany.yourapp") // Writing data sharedDefaults?.set("Hello, Shared World!", forKey: "sharedMessage") // Reading data from the group if let sharedMessage = sharedDefaults?.string(forKey: "sharedMessage") { print(sharedMessage) // Output: Hello, Shared World! }
