I applied via Referral and was interviewed before May 2023. There were 2 interview rounds.
Basic coding qustions
MVC is a design pattern that separates an application into three main components: Model, View, and Controller. MVVM is a variation of MVC with an added ViewModel layer.
MVC stands for Model-View-Controller, where Model represents the data, View represents the UI, and Controller acts as an intermediary between Model and View.
MVVM stands for Model-View-ViewModel, which adds a ViewModel layer between the View and Model. Vi...
Memory management in Swift involves automatic reference counting (ARC) to manage memory allocation and deallocation.
Swift uses automatic reference counting (ARC) to track and manage memory usage.
ARC automatically deallocates objects when they are no longer needed.
Developers can use weak and unowned references to prevent strong reference cycles.
Using value types like structs can help reduce memory management issues.

I applied via Naukri.com and was interviewed in Sep 2020. There were 4 interview rounds.
Classes and structures are both used to define custom data types, but they have some key differences.
Classes are reference types, while structures are value types.
Classes support inheritance, while structures do not.
Classes have deinitializers, while structures do not.
Classes have reference counting for memory management, while structures do not.
Classes can have optional property types, while structures cannot.
Retain cycle is a memory management issue where objects reference each other and cannot be released. It can be avoided by using weak or unowned references.
Retain cycle occurs when two or more objects hold strong references to each other.
To avoid retain cycle, use weak or unowned references instead of strong references.
Weak references do not increase the reference count of an object and automatically become nil when the...
Opinion binding is a legal doctrine that requires judges to follow the decisions of higher courts in similar cases.
Opinion binding is also known as stare decisis.
It helps to ensure consistency and predictability in the legal system.
For example, if a higher court has already ruled that a certain law is unconstitutional, lower courts must follow that ruling in similar cases.
Opinion binding can be controversial, as it can...
GCD and Operation Queues are both used for concurrent programming in iOS, but differ in their approach.
GCD is a C-based API that uses a thread pool model for concurrency.
Operation Queues are built on top of GCD and provide a higher-level abstraction for concurrency.
GCD is best for simple, lightweight tasks, while Operation Queues are better for more complex tasks with dependencies.
GCD uses blocks for task execution, wh...
The life cycle of iOS applications refers to the stages an app goes through from launch to termination.
The app is launched by the user or system
The app enters the foreground and becomes active
The app can be sent to the background or suspended
The app can be terminated by the user or system
The app can be resumed from the background or suspended state
The app can receive memory warnings and handle them appropriately
The UIViewController life cycle consists of several stages that occur when the view controller is loaded and unloaded.
viewDidLoad() - called when the view controller's view is loaded into memory
viewWillAppear() - called just before the view appears on the screen
viewDidAppear() - called just after the view appears on the screen
viewWillDisappear() - called just before the view disappears from the screen
viewDidDisappear()...
I applied via Company Website and was interviewed in Jul 2020. There was 1 interview round.
Questions about basic Swift knowledge and past work experience.
Basic Swift concepts such as optionals, closures, and protocols may be asked.
Questions about past projects and how you approached problem-solving may also be asked.
Examples of past work experience and projects may be requested.
Questions about Swift syntax and best practices may be asked as well.
Clean coding principles ensure code readability, maintainability, and scalability.
Use meaningful variable and function names
Keep functions short and focused
Avoid code duplication
Follow SOLID principles
Write unit tests
Refactor regularly
I approach problem-solving by breaking down issues, analyzing requirements, and iterating solutions based on feedback.
Identify the problem clearly: For example, if an app crashes, check logs to pinpoint the issue.
Break down the problem: Divide a complex feature into smaller tasks, like implementing UI and backend separately.
Research and gather information: Use documentation and forums to find best practices or similar ...

Objective-C is the older language used for iOS development, while Swift is the newer, more modern language.
Objective-C is a superset of C with Smalltalk-style messaging syntax.
Swift is more concise and easier to read than Objective-C.
Swift is safer due to its optionals and type interference features.
Objective-C has been around longer and has a larger codebase, but Swift is becoming more popular.
Many developers prefer S...

ARC (Automatic Reference Counting) in Swift is a memory management system used to automatically manage memory allocation and deallocation.
ARC keeps track of how many references there are to an object and automatically deallocates it when there are no more references.
Use strong reference cycles can lead to memory leaks, so use weak or unowned references to break the cycle.
ARC is the default memory management system in S...
Automatic Reference Counting (ARC) manages memory in iOS apps, ensuring efficient resource use and preventing memory leaks.
ARC automatically tracks and manages the app's memory usage.
Objects are deallocated when there are no strong references to them.
Use 'weak' references to avoid retain cycles, e.g., delegate properties.
Example: 'var delegate: MyDelegate?' is a weak reference.
ARC simplifies memory management compared ...
MVVM (Model-View-ViewModel) is an architectural design pattern commonly used in iOS development to separate concerns and improve code maintainability.
MVVM separates the user interface (View) from the business logic (ViewModel) and data (Model).
ViewModel acts as an intermediary between the View and the Model, handling user interactions and updating the data.
Swift provides tools like Combine framework for reactive progra...
