Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Setting up an RxSwift environment"

A block of code is set as follows:

use_frameworks!
target 'YOUR_TARGET_NAME' do
pod 'RxSwift'
pod 'RxCocoa'
end

Any command-line input or output is written as follows:

 sudo gem install cocoapods

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Now pick the recently installed Swift 4.0 Snapshot and restart Xcode IDE"
