Q1. What is Weak & Unowned , ARC?
Ans. 
Weak & Unowned references are used in ARC to prevent retain cycles in Swift programming.
• Weak references do not increase the retain count of an object, and automatically become nil when the object is deallocated.

• Unowned references do not keep a strong reference to the object, and can become a dangling pointer if the object is deallocated.

• ARC (Automatic Reference Counting) is a memory management system used in Swift to a

Q2. What is Autoclosure?
Ans. 
Autoclosure is a feature in Swift that automatically wraps an expression in a closure.
• Autoclosure is used to delay evaluation of an expression until it is actually needed.

• It is commonly used with functions that take closures as arguments, allowing the caller to pass in a regular value instead of a closure.

• Autoclosures are created by adding @autoclosure attribute before the closure's parameter type.

Q3. Code snippets for optional binding, find error ?
Ans. 
Optional binding in Swift helps to safely unwrap optionals and check for nil values.
• Use if let or guard let to safely unwrap optionals and bind the value to a new constant or variable.

• Check for nil values before using the unwrapped value to avoid runtime errors.

• Example: if let name = optionalName { print(name) }

• Example: guard let age = optionalAge else { return }

Q4. What are Access Controls/modifiers? public vs open?
Ans. 
Access controls/modifiers determine the visibility and accessibility of classes, methods, and properties in object-oriented programming.
• public access control allows a class, method, or property to be accessed from anywhere in the code

• open access control allows a class to be subclassed outside of the module where it is defined

• public is commonly used in Swift for most cases, while open is used when you want to allow subc

Q5. Protocol vs Closures?
Ans. 
Protocols define a blueprint of methods, properties, and other requirements that a class or struct must adopt. Closures are self-contained blocks of functionality that can be passed around and used in your code.

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...read more
