Conventions

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.

All Android and iOS examples and descriptions are based on Android Studio, xCode and various third party services, running on a OSX machine.

Console input is shown as:

$ gem install cocoapods

A block of code is set as follows:

func refresh (sender: AnyObject!) {
...
        let cngQuery = client.queryDataset("wwmu-gmzc")
        cngQuery.orderAscending("title").get { res in
            switch res {
            case .Dataset (let data):
                self.data = data
...
        }
    }
Data (XML, JSON or otherwise) is shown as:
<key>UberClientID</key>

    <string></string>
    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>uber</string>
