Yes. My name is Ankur Kumar. I have a total of 5.5, 5 years of experience in iOS. In my career, I have worked with many various clients, including ecommerce platforms, gaming platforms, as well as features like audio calls, video calls, socketing, and clean number sense. I have completed more than 20 applications in that. I have also uploaded them to the app store and reviewed them.

Yes. For the technique, I have applied for the network layer exception in iOS. I have used the various methods, like Alarm of Fire and as well as the core native URL sessions. For Alarm of Fire, we have used AF methods, which usually call get and post methods to get the response from the APIs. And for the URL session, it will build on the task, and we have to continue calling the task to get their response. We have to use a try-catch method to get the response with a particular model.

Yes. To manage the dependencies among the various components within iOS projects, I'm checking how many dependencies we need, including third-party libraries. After that, I will create the code file using the `swift package init` command. Then, I will open the code file using the `swift package open` command, and write down all the dependencies. After closing the package file, I will install the package using `swift package install`. And then, we have to open the Xcode workspace file. After that, in the view controller file, we need to import and port them. So the library or the dependency will be loaded in that particular controller file. And then, yes, we can use it in our new controller file. Thank you.

Yes, I will implement the custom animation between 2 new controllers using the segment methods as well as if we can use UI's any meta animation method. And if we are using the constraints in there, then first of all, we have to change the concern when you like if I'm in general, I mean my concern is outlets, then firstly I have to change the value of that outlet. And then after I will just have to call the view's layoutSubviews or view layout matters, and it will automatically animate the two views. Also in the view controller if we have to change the view controller by using some animation then we can also use the navigation controller's animation method, and we can beat that.

Yes, for the efficiency of storing and returning user preferences in the iOS application, we can store the data in singleton classes and in Core Data and user defaults. So, singleton is used for one-time values. Whenever the user application reopens, we can find the value of data from the API and show it in the singleton class. Whenever we clear the application or close it, the singleton data will be destroyed. After that, in Core Data, we have to create tables and store the data with sessions. Like, if a user is doing logging, and then user data will be shown in Core Data. And when our user comes again next time and data is not available internally, then we can retrieve the data from the database. And in user defaults, we can use the same, but it will be storing user default methods. And in user default methods, we can store data in different models. And yes, we can return the data from user defaults dot standard dot get.

Yes. To handle the error in the suite, we can use the try-catch method as well as optional binding and optional changing methods. Whenever we are handling errors, any errors that occur while using from the APIs, we can use the try-catch method if we are passing any data in here. So then we can use try to measure. And if we are handling the error from any model, then we can use optional training and optional binding.

Yes. In this code, when we are loading in the data and the runtime exception will be listed with an ID, like if we have only items in the screen and we don't have the ID, that's why it will execute the runtime here. Thank you.

Yes. In this, it will be missing the note task method at the end of URL session, like, whenever in this current code, URL session dot shared dot data task with URL. In the end of call, we have to write that task method to call the API or to call the network method. Yes. That's it.

Yes. We have used the MVVM, MVC, and MVP methods. That is, we have used design patterns beside MVC. In the MVVM, we have the model view controller. So we have one model view file, we have one view controller file, and we have one data model file. That is, for the view model, we are storing the models and the API coding part in the view model. So in the view controller, we have the functions and logics everywhere. So, the new VM and apart from that, we have used the MVP. In the MVP, we have used the 1V for view, I for interactor, P for presenter, and R for router. So, yes, there are 4 types we have used in MVP. Also, we can merge NVVM and MVP both, like VIPER and plus MVVM design patterns as well.

Yes, to optimize the startup time of the iOS regression, we can avoid the initial run time API calling. To start up the application quickly, we can call the API in the background process whenever the application is opening. This will directly show the flash screen and the home screen. In-depth, we can parallelly call the API in the background process, which will deploy the startup panel by us.

Yes, so in the iOS set, I'm debugging from where I'm getting the trace. If we are getting a trace from any force or anything or any try-catch block, I will use another method. It's like optional binding or optional unwrapping, and we can find the debug and find the place that is missing. Sometimes in the index part, they'll create sometimes the data is null. So null trace is also there so we can debug like that. Thank you.
