This book is an exploration of the programming features introduced in iOS 9. iOS 9 has introduced a number of frameworks to the iOS, and these frameworks were not available nor supported in the previous versions of iOS. The first part of the discussion is based on the Contacts framework which was introduced for the first time in iOS 9. This framework makes it easy for developers to manage applications. The process of creating contacts is discussed in this book, spelling out how to do that in iOS 9. The book also guides you on how to search for the Contacts which have been stored in the contacts database of your device. Different methods on how these contacts can be searched for, such as by use of predicates are discussed. You will also learn how to fetch contacts from the database and then display them in a table view. The output which you get can be formatted for a nice appearance. The book guides you on how to do this. The Core Spotlight framework is also explored, including how to use it so as to make apps more discoverable.
