- Q1. What is Protocol in swift?
- Ans.
Protocols in Swift define a blueprint of methods, properties, and other requirements that a class, struct, or enum must adopt.
Protocols are used to define a set of rules or capabilities that a type must conform to.
They allow for code reuse and provide a way to define common behavior across different types.
A type can adopt multiple protocols, enabling it to conform to multiple sets of rules.
Protocols can require propert...
- Q2. What is Dependency Injection.?
- Ans.
Dependency Injection is a design pattern where the dependencies of an object are provided externally rather than being created internally.
Dependency Injection helps in achieving loose coupling between classes.
It allows for easier testing and maintenance of code.
There are three types of Dependency Injection: Constructor Injection, Setter Injection, and Interface Injection.
Example: In iOS development, we can use Dependen...
- Q3. What is Generics in swift.?
- Ans.
Generics in Swift allow you to write flexible and reusable code by creating functions, classes, and structures that can work with any type.
Generics enable you to write code that can be used with different types, without duplicating code.
You can define generic functions, types, and protocols to work with a wide range of types.
Generics are particularly useful when working with collections, such as arrays and dictionaries...
- Q4. What is Associate types ?
- Ans.
Associate types are a way to create a relationship between two types in Swift.

The conforming type can provide its own concrete type for the associated type.
This allows protocols to be more flexible and reusable.
For example, a protocol for a container type c...
