cncontact

I'm trying to insert into var contacts: [CNContact] = [] the var store = CNContactStore() but I did not find the right code for this job, i found this function that I need to give that a name func findContactsWithName(name: String) { AppDelegate.sharedDelegate().checkAccessStatus({ (accessGranted) -> Void in if accessGranted { dispatch_async(dispatch_get_main_queue(), { () -> Void in do { let predicate: NSPredicate = CNContact.predicateForContactsMatchingName(name) let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactBirthdayKey, CNContactViewController

I am able to observe the CNContactStoreDidChangeNotification when the contact database is changed while the app is in background state. I am pretty sure that only one observer was added to NSNotificationCenter . The problem is NSNotificationCenter posts MULTIPLE times (2, 3, 5, and even more times) even if I only add one new contact. Where is the problem? Make certain you aren't adding the observer multiple times. This can happen without you realizing it if (for example) you call -addObserver from -viewDidLoad or -viewDidAppear in your view controller (as these might get called more than once

[Appears to be fixed in iOS 10!] So what follows applies to iOS 9 only... I have been experimenting with Apple's new Contacts framework, and I've found a huge bug in one of the three forms of CNContactViewController. It destroys the surrounding interface so that your app becomes useless; the user is stuck. To make this bug easy to see, I've posted an example project at https://github.com/mattneub/CNContactViewControllerBug . To experiment, run the project and do the following steps: Tap the button (Unknown Person). Grant access if requested. You are shown the partial contact, in our navigation
