(2 Questions)

  • Q1. What is difference between class and struct?
  • Ans. 

    Classes are reference types, while structs are value types in Swift.

    • Classes support inheritance, while structs do not.

    • Classes have deinitializers, while structs do not.

    • Classes can have reference counting for memory management, while structs do not.

    • Example: class Person {} vs struct Point {}

  • Answered by AI
  • Q2. What are optional?
  • Ans. 

    Optionals are a feature in Swift that allow variables to have a value or be nil.

    • Optionals are used to handle situations where a value may be missing.

    • They are denoted by adding a '?' after the type declaration.

    • Optionals must be unwrapped before their value can be used.

    • Example: var name: String? = "John"

    • Example: var age: Int? = nil

  • Q1. Difference between retain, copy and strong?
  • Ans.

    • Retain: Increases the retain count of an object, ensuring it is not deallocated as long as there are references to it.

    • Copy: Creates a new copy of an object, ensuring that changes to the original object do not affect the copied object.

    • Strong: Similar to retain, it increases the retain count of an object and ensures...

    Classes are reference types, while structs are value types in Swift.

    • Classes are reference types, meaning they point to the same memory location when assigned to a new variable.

    • Structs are value types, meaning they create a new copy when assigned to a new variable.

    • Classes support inheritance, while structs do not.

    • Classes can have deinitializers, while structs cannot.

    Concurrency is the ability of a system to execute multiple tasks simultaneously.

    • Concurrency allows multiple tasks to run at the same time, improving performance and responsiveness.

    • It can be achieved through techniques like multithreading and asynchronous programming.

    • Concurrency is important in iOS development for tasks like networking, data processing, and UI updates.

    • Manual Reference Counting (MRC) - requires developers to manually manage memory by retaining and releasing objects.
