Difference between == and === in Swift

== - Compares the value of the variable

=== - Along with value the data type also need to be matched.

Protocols in Swift

What is a Protocol?

In swift protocol is considered as a major property which we use frequently.

It basically means what are the things we are necessary to be handled. It is considered as a set of rules which are mandatory to define on using the protocol

Ex: consider a Vehicle

If we need to buy a car what are the things we take care first (speed, milage, kms) so these are the necessary things that everyone needs to know.

So, we declare all of them in a protocol

Any vehicle need to satisfy these properties(car/bus/plane)

Structure of Protocol:

Here every protocol have mandatory rules soo

Any class which conforms to this protocol need to provide definition for this.

In simple words for people who knows Java Programming Language

Protocol is just like an interface in Java

Any class which implements that interface need to provide definition.

API INTEGRATION IN SWIFT(part 1)

API means Application Programming Interface

It's main purpose is to bring applications together in order to perform a designed function.

It helps us to make repetitive yet complex processes highly reusable with a little bit if code.

Overview of API

Via theory wise first in order to get the data from API we need to send a request.

So, we prepare a request object.

A Request object contains

• URL

• Header Parameters

• Body Data

In code wise we need to follow several steps to achieve that task of getting the data via API

So theory wise get to know these things.

We will continue this in the next part🤗

Happy learning!!

Methods in Swift

What is a method in swift?

Methods are considered as small piece of code that is reusable. They belong to the classes, enums, structs.

Methods use func as a keyword to provide a definition

Structure of method:

These methods are placed inside the class, struct Or enum.

Swift allows classes to have methods with the same name but there need to be a difference either in

Number of parameters

Datatype of parameters

Order of parameters

Name of parameters

Methods can have a return type as well. Usually that return type is placed at end of the method.
