+/**
+ * The RCTAppDelegate is an utility class that implements some base configurations for all the React Native apps.
+ * It is not mandatory to use it, but it could simplify your AppDelegate code.
+ *
+ * To use it, you just need to make your AppDelegate a subclass of RCTAppDelegate:
+ *
+ * ```objc
+ * #import <React/RCTAppDelegate.h>
+ * @interface AppDelegate: RCTAppDelegate
+ * @end
+ * ```
+ *
+ * All the methods implemented by the RCTAppDelegate can be overriden by your AppDelegate if you need to provide a
+ custom implementation.
+ * If you need to customize the default implementation, you can invoke `[super <method_name>]` and use the returned
+ object.
+ *
+ * Overridable methods (New Architecture):
+ *   - (Class)getModuleClassFromName:(const char *)name
+ *   - (std::shared_ptr<facebook::react::TurboModule>)getTurboModule:(const std::string &)name
+                                                      jsInvoker:(std::shared_ptr<facebook::react::CallInvoker>)jsInvoker

+ *   - (id<RCTTurboModule>)getModuleInstanceFromClass:(Class)moduleClass
