In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows:
"Next, we'll create the method that will take an Int and return PoolBallType".
A block of code is set as follows:
func poolBallType(forNumber number: Int) -> PoolBallType {
if number < 8 {
return .solid
} else if number > 8 {
return .stripe
} else {
return .black
}
}
Any command-line input or output is written as follows:
brew install postgres
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The repository landing page provides the structure and location of JSON configuration file under Configure PostgreSQL".
