I'm excited to share my experience in mobile application development. I have 9 months of experience, but I've also worked with technologies that have 9 years of experience. So, I have experience with Objective-C, with 3 years of experience, and Swift, with 6 years of experience. During my career, I've developed over 50 applications. I've deployed over 30 applications, and most of them are available on the App Store. Recently, I worked on a poker card game using Swift UIKit features. I've also worked on other related applications, such as swapping business applications or training applications, event management applications, appointment booking applications, and grocery applications. In addition, I've worked with various features, including memory management, iOS permissions, location management, in-app assist features, iOS widgets, share extensions, iOS watch apps, and integrations with third-party payment gateways and social networking. I use Bitbucket and GitHub for code versioning and Jira, Asana, and ClickUp for tracking and development. For design development, I use Figma and Adobe XD. I follow design patterns like MVC and MVVM for clean code in development, and I also perform unit testing during development.

Excuse me, where you use design pattern to solve a problem. Nice. For iOS design patterns, normally, I'm using the MVC model view controller. And now in these days, we are using the MVVM, model view model design patterns in ASW and development. And for your design patterns, how to problematize. If we are using multiple screens and using repeated view models in our code, then it will be easier to implement the MVVM design pattern in our application. And MVC is containing all properties and API calling features in the same controller. So using MVVM, we can create a separate view model part that contains all properties and data members in the view model and also has the same responsibility in the view model for calling APIs. So this view model can be used for multiple screens in multiple view controllers, then it will be used for code reuse in development. And should you do a common view model? We can write minimum code in development. And also, we can say it's 82 implement the clean code feature in development. And suppose they have our login screen and sign up screen. So if we use MVC, then we need to create two separate controllers, and both separate controllers will contain their own properties and API calling features that are part of MVC. And if we use MVVM, then our single model view can be used for both controllers for login and sign up, and it's a best example of MVVM part that we are using reusable view model code in both screens.

To handle errors in the network layer using saved data. If the question is related to API errors that we are getting in a response, then we need to create multiple error handling in our network API class. And we can identify separate errors with their codes. And we can set a specific message related to errors when we get from API response. And if this error handling is related to our network layer, then we can use the inbuilt network handling feature provided in the iOS native network layer class. So we can inherit and use their predefined error codes, and we can set their priority, which error can be used on a priority basis.

We would manage state in a complex multithread iOS application using a combined framework that provides a synchronous implementation of asynchronously flow. Using Combine, we can set a property state in a publisher, and the subscriber will provide their current state. And when the property is changing its data in a state, then the subscriber will provide their existing state that we added in the publisher.

Using iOS animation, they have multiple techniques to implement animation in an iOS application. The first is using iOS native UIA animation and Core Animation, which provides multiple types of animation inbuilt natively. The second approach is using a third-party script file with Lottie, which offers a script animation file that can be implemented in our application. We can also use any GIF image for static animations that repeat. If we use Core Animation, it does not affect our iOS application's performance, making it easy to perform and use in iOS native code. That is the best approach.

You're approach to optimize UI response in complex sizes using size classes can optimize our UI responsive and complex application. Using size classes provides a layout view of the iOS app for every device with compatible features. And this is providing the type of component, regular, compact, and unspecified. These are the size classes that we are using in file development. And suppose our iPhone is in particular and landscape, then it will use the regular size classes. If our iPhone is, sorry, it's using the particular and horizontal size classes, which is regular and compact. And our device in landscape mode will use the compact size classes. If our device is related to plus devices, such as iPhone 7 plus, 8 plus, then in landscape mode, it will use the compact regular size classes. If size classes are working with the iPad, it's normally regular. And also for landscape mode, it's using the regular size classes. Size classes basically convert UI responses for every device commonly. If a device has a low screen size, then it reduces the size plus data and optimizes the UI according to the device's responsiveness. If a device is large in size, then it scales the UI according to the device size in landscape and portrait to both.

In this function using dispatch queue property in a method, but its error will be so dispatch queue not in scope because this is declaring below of the method. So it should be declared before use in a method. Otherwise, we can use above of the method. Means, we need to initialize and declare before it uses that error will be solved.

What each? In the singleton pattern, and in the wrong in this information, how to fix. Using this code, this is creating an object, and we can say instance, like app manager dot share manager. It's creating a let manager instance. So using the manager instance, we are calling a method, doing something. So in this single singleton pattern, protocol, we can't create any reference, any object of the class because this is the singleton class is providing a global access in all of our project. So it should be used by app manager, share manager dot their method name and property name. So we can't create any other instance of or object of the given class. That's it.

When designing a scalable app architecture for a growing user base in an iOS app, we approach this by dividing the architecture into multiple layers. The first layer is Cocoa Touch, which includes UI-related frameworks such as UIKit and game kit frameworks. For offline data storage, we can use core services to save data in a core database like SQLite. We also have many preferences in iOS, and we can use our app architecture to design a scalable application based on the usability of the project. If our app is working with core OS features like Bluetooth, we can use the core Bluetooth frameworks and also hardware-related features like user authentication with device. They have a local authentication framework. Our architecture is divided into multiple layers: the first is Cocoa Touch, the second is the media layer, and the third is core OS. Based on the usability of the project, we can design a good scalable application. If our application is using media-related features, we can also use the media layer to process images, audio, and video, and to get data from the library and camera-related features.

I'm employed through a method. I'm sure the iOS app user interface is still responsive. The method I will employ to ensure an iOS app user interface stays responsive during heavy computational tasks is to use multiple threads. You need to face the fact that we have multiple ways to implement iOS UI. We were doing different user interfaces to stay up to the way they're providing a coding part for the user interface in the app, and the UIA kit is providing a storyboard and Xcode can use XIB controls for preparing the design part and implementing every computational task in design time. And I would prefer to use the UI kit that is providing multiple ways to write heavy designs in storyboard by overriding XIB files for separate UI customized controls by XIB controls.

Majors with different disabilities. Accessibility of iOS applications is provided in multiple ways. We can use deep learning features. So, using customized URLs, we can access our iOS application. We can also use various extensions. We can access our application data both in-house and outside of the iOS application. There is also a share extension feature, so we can access our iOS application outside of iOS support. The share extension is basically used when selecting an image from the photo library. When we select an image, our app will be listed to open the image in our application. This is a part of different ways to open our iOS application for support. First, there is deep linking. Second, there is iOS widgets. Third, there is cell extension. We can also set our local post notifications and remote post notifications to access our application from outside the iOS app. We can also get real-time data without using our iOS application. Actually, deep linking has two techniques to access our application. The first is the URL scheme, and the second is the universal link. URL schemes also provide a way to open our app from outside, like opening it through Safari.
