Since UIViewController is supposed to be a Controller in the MVC pattern, and it’s already doing a lot with the Views, we can merge them into the View of our new pattern - MVVM. In the MVVM design pattern, Model is the same as in MVC pattern. It represents simple data.
Consequently, Before diving in the code, here is a quick introduction to this pattern. MVVM stands for Model, View, ViewModel, a specific architecture pattern where the ViewModel stands between View and Model providing interfaces to imitate UI component. This connection is made by “binding” values, linking logical data to the UI. Thereof, The View Model is a key piece of MVVM pattern. View model acts as a bridge between the view and the model. Each view class has a corresponding view model where it gets its data from. View model retieves data from the model, manipulates the data into a format required by the view, and notifies the view to show this data. In addition, Here is the architecture of MVVM: In the MVVM design pattern, view and controller are closely coupled together and treated as one component. It can also be represented as UIView or UIViewController objects, accompanied by their .xib and .storyboard files. Just so, View Controllers manage UIView s and other UIViewController s. An iOS application has a single window, but many screens, each of which may contain several UIView s. Managing those screens is complex and requires responding to both user input and changes in the model (problem domain).

How does the uiviewcontroller react to orientation changes?
This is poorly designed because a UIView should not react directly to orientation changes. This is the job of the UIViewController. Moving on, the UIDeviceOrientation is the current orientation of the device itself, not of the user interface currently displayed within the device.
Is the sheet modal backed by a uiviewcontroller?
After researching it a bit, .sheet () modals, are in fact, backed by a real UIViewController. The challenge is tapping into the backing UIViewController of our SwiftUI modal. This article, will be all about it. It may seem too much code to accomplish something so simple.
How to use uiviewcontroller and uiviewrepresentable in swiftui?
Here is the final result: The process of integrating UIView is almost identical to the one of UIViewController. Namely, the SwiftUI view must conform to the UIViewRepresentable protocol and implement the same set of methods. Here is an example of how we can represent UIActivityIndicatorView in SwiftUI:
How to create custom initializer for uiviewcontroller?
The slightly more complicated solution is to create a custom initializer that gives properties default values in one place, then calls super.init (). When working with UIViewController and storyboards, the initializer you will want to override should look like this:
Is there a uiviewcontroller with blur background in swift?
UIViewController with blur background in Swift — iOS The blur effect is often used in Apple’s official apps. The bad news is that Apple doesn’t provide any native API in the UIViewController Class to implement the blurred background.
Is it possible to pop a uiviewcontroller?
Though it is possible to present UIViewControllers both modally and via a push, UIViewControllers can only present other UIViewControllers. Therefore, UIViewControllers can only be dismissed (unless they are inside a UINavigationController stack and the UINavigationController is handling the pop — see lesson #2).
How does swiftui work as a uiviewcontroller?
SwiftUI has no concept of UIViewController, everything is just a View. For SwiftUI to work as UIViewController you just set it as a rootView of UIHostingController like the example above.
