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

First Open the project Step 1: Ask permission to allow the notifications

Add the import in App Delegate import UserNotifications

In AppDelegate --> create a method functions() --> Add the logic

func notifications() {

let notificationCenter = UNUserNotificationCenter.current()

        notificationCenter.requestAuthorization(options: [.sound, .badge, .alert]) { s, err in logic }

}

Call this method in App Delegate didFinishLaunchingWithOptions()

Step 2: Open Terminal and go to the path where this apns file is saved

Type the following command which includes How to get deviceId: Xcode --> Windows --> Devices and simulators --> Simulators --> choose the running simulator --> copy the deviceid

When we are doing projects we might need to switch between users like our friend might use our machine and wanted to push their code to their project. Even at the initial setup of the git project we need to provide our user credentials. So, as we already know Git always have a easy solution  Open Terminal --> Goto the path of specific project --> type git 

If git is already there then we will get git help documentation . If not,  git init --->  git config --global user.email "[email protected]" --> git config --global user.name "keerthidevipriya"

== - Compares the value of the variable

Step 1: Check whether git is installed in your system or not.

How to check 🤔. Is this your question answer is simple.

Open command line/terminal ----> git ----> if after entering git of it won't show any error then you can say git is installed in your system.

Step 2: Open your github account and create a new repository in your github .

Top right corner ----> click on + or add ---> Choose new repository ---> give permissions only which are needed ----> Click create

Wohoo! Done creating a new repository in remote.

Step 3: Now our task is to connect our local repository to remote repository (GitHub repository) . Follow the below series of steps

Open cmd line / terminal ----> Go to your local project path ---> git init ---> git remote add origin https://(repo_name)

Note:: repo_name is accessible from your github repository on choosing thr repository which we have created copy and paste here.

Now you have connected your local project to remote github repository project.

Step 4: Connecting our local branch to remote branch

git branch -M main

If you get any errors do not worry that branch is already existed. Go ahead with the next command

Step5: Pushing our local branch to remote branch

git push -u origin main

This doesn't work then try something like

git push --set-upstream origin master

The one good thing about command line in git is it always suggests you the proper command. That's the specialty of git in command line/terminal.

That repo link is mine update with your project repo link😅 dear.

It won't end our task now.

Now we need to commit and push our changes in our project right

First Check the changes in your project

git status

git add .

git commit -m "message"

git push

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🤗

• It is a powerful and intuitive programming language built using a modern approach for iOS.

• It ensures safety, performance and software design patterns.

• The syntax is concise yet expressive.

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.

Tadaaa!! Being new to development editor we always feel excited to change the themes especially people who likes Dark theme

So, today we can learn how to change theme in xcode

Open Xcode ----> Preferences ----> Choose Themes on top -----> Choose available themes on left side ----> select one of them

You can also add your own customized theme 🤗

It's as simple as that
