What is iOS activity?

iOS device (IPhone OS device) Products that use Apple’s iPhone operating system, including the iPhone, iPod touch and iPad . It specifically excludes the Mac. Also called “iDevice” or “iThing.” See iDevice and iOS versions.

Views allow you to control how, when, and where data is presented to the app user, and how the user interacts with the data .

The Activity app on your Apple Watch keeps track of your movement throughout the day and encourages you to meet your fitness goals . The app tracks how often you stand, how much you move, and how many minutes of exercise you do. Three rings in different colors summarize your progress.

A view controller manages a single root view, which may itself contain any number of subviews . User interactions with that view hierarchy are handled by your view controller, which coordinates with other objects of your app as needed. Every app has at least one view controller whose content fills the main window.

A scene contains the windows and view controllers for presenting one instance of your UI . Each scene also has a corresponding UIWindowSceneDelegate object, which you use to coordinate interactions between UIKit and your app. Scenes run concurrently with each other, sharing the same memory and app process space.

WebView can be defined as an object which can display the interactive web content and load HTML strings within the iOS application for an in-app browser . It is an instance of the WKWebView class, which inherits the UIView class.
