Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}'

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

/* 
    Variables are data stored that can have their value change whenever we want it and 
    constant are value that can not be changed.

    The advantage of using var in declaring a variable and let in declaring a constant is that 
    it help xcode to remind us of the constant we have set and whenever we try to change it,

Replacing the SceneDelegate When Running Unit Tests

Overview

I've been working through the exercises in the excellent iOS Unit Testing by Example book by Jon Reid, which I highly recommend. However, the book is in beta at the moment and there are some curveballs thrown by iOS 13 that aren't handled in the text yet. Specifically, when I hit the section about using a testing AppDelegate class I thought "This is very good. But what about the SceneDelegate?"

In Chapter 4 the recommendation is to remove the @UIApplicationMain decoration and make a manual top-level call to UIApplicationMain. To wit:

import UIKit

    case delete = "DELETE"
    case get = "GET"
    case patch = "PATCH"
    case post = "POST"
    case put = "PUT"
}

enum HTTPScheme: String {
    case http
