- Q1. Encription and decription in swift

Encryption and decryption in Swift involves using cryptographic algorithms to encode and decode data securely.
Use common encryption algorithms like AES or RSA for encryption.
Implement encryption using libraries like CommonCrypto or CryptoSwift.
Store encryption keys securely and use secure protocols for data transmission.
Example: Encrypting a string using AES encryption in Swift.
- Q2. Keychain access in swift
- Ans.
Keychain access in Swift allows secure storage of sensitive information like passwords, tokens, etc.
Use Keychain Services API to securely store and retrieve sensitive data.
Keychain items are stored securely in the device's keychain and are encrypted.
Access keychain items using unique identifiers called keys.
Use Keychain Swift library for easier implementation.
- Q3. Class vs struct
- Ans.
Classes are reference types, while structs are value types in Swift.
Classes are reference types, meaning they point to the same instance in memory when assigned to a new variable.
Structs are value types, meaning they create a new copy when assigned to a new variable.
Use classes for complex data structures or when you need inheritance, use structs for simple data types or when you want value semantics.
Example: class Per...
- Q4. If let and guard let
- Ans.
Both 'if let' and 'guard let' are used for optional binding in Swift, but they serve different purposes and scopes.
'if let' allows you to safely unwrap an optional within a conditional block.
Example: if let name = optionalName { print(name) }
'guard let' is used for early exits and requires the unwrapped value to be available after the guard statement.
Example: guard let age = optionalAge else { return } // age is availa...
- Q5. Grand central dispatch in swift
- Ans.
Grand Central Dispatch (GCD) is a technology in Swift for managing concurrent operations.
GCD allows developers to perform tasks concurrently without having to manage threads manually.
It provides a high-level API for managing tasks and executing them on different queues.
Developers can use GCD to perform tasks in the background, update the UI on the main thread, and more.
