Using Apple’s Contacts framework, we’ll be able to request permission from the user and access their contacts information in their address book. The code to do this is extremely simple and I’ll show you how in this video.

Great concepts here Chris! I recently had to export my Contacts from my work iMac to my new home office iMac. Some of the imported data landed in the wrong slots. This tutorial will help me to create a process to verify and update items that are incorrectly formatted. Thanks for this! Your tutorials are always very easy to understand and so many times you seem to find items that I have been curious about.

Nice intro. Would be good to cover contacts ui too. Hard coding display strings is limited. Also, how are custom phone types handled?

hey chris, how can i access favorite contacts in contacts frame work?

@aldobergamini462 4 ай бұрын

Very nice video! I do have a question, that is about something of a follow up to this intro, but in the same area of iOS Is it possible to add custom fields to contacts in system contacts database? Say your app is about matching people with the ice cream they like and you do not want to have your own db, that would need to be kept in synch with system contacts...

Hi Chris, I love your videos and your tuts. They are great and I learned so much. But this lesson took me half a day to find a solution, why your code doesn't work on macOS. No errors in code but access to contacts wasn't granted and never asked and debugging with print(error.localizedDescription) always said: Access denied. For all having the same problem on macOS: go to project info in your project. Select "TARGETS" and choose the tab "Signing & Capabilities". There scroll down to "App Sandbox" and check App Data -> Contacts. Et voilá!
