However, the Contacts framework does not lookup just there when an app asks for contact data. The main source of contacts data is always the database existing in a device. Furthermore, keep in mind that the user is always eligible to change the authorization state of the app through the device Settings, so you should always check if your app has the required permissions to access the contacts data or not right before you perform any related task. In a while we’ll talk more specifically about it, and we’ll see how all possible situations are handled programmatically. If, on the other hand, users prohibit access to the contacts data, then this decision must be respected by the app and not interact with it at all. If they do so, then the app can freely interact with the user’s contacts database. Users are always being asked if they grant access to their contacts data through an application.

So, first of all, I’ll begin by something crucial, and that is the user privacy. I won’t go into much details, as you can find them all in the official Apple documentation, and the WWDC 2015 session 223 video. In the next few paragraphs we’ll highlight the most important aspects of the Contacts framework. All that belongs to history, as the new Contacts framework is way simpler to understand and use contacts can be fetched, created or updated in no time at all, the contacts-related development time can be dramatically decreased, changes and modification can be done really fast. In general, the AddressBook was difficult to understand and manage, and that fact was even more intense in new developers. The greatest example in iOS 9 is the all brand new Contacts framework, which is here to replace the old AddressBook framework in a fashion modern, simple and a lot more straightforward.Įvery developer that has dealt with the AddressBook API in the past can definitely say that it wasn’t the most easy part of the iOS SDK to work with. Additionally, and that’s always surprising, there are cases where old APIs are left aside and become deprecated, making room for new ones that have been implemented from ground up to fill in the gap instead. As we’ve all witnessed, there’s a number of new stuff that has been first-introduced in this version, but there are changes and updates to existing frameworks and libraries as well. As every iOS release, the version 9, which is officially here for just a few weeks, presents new features and improvements to existing technologies for both users and developers.
