CNContact for Mac OS X 10.11 - macos

Question

from OS X 10.11 and iOS 9.0 Apple provided this framework Contacts:
https://developer.apple.com/library/prerelease/mac/documentation/Contacts/Reference/Contacts_Framework/index.html#//apple_ref/doc/uid/TP40015328
and I would like to access contacts from Mac, but I cannot do anything, because the app does not have access to contacts:
switch CNContactStore.authorizationStatusForEntityType(.Contacts) {
case .Authorized:
print("Authorized")
NSUserDefaults.standardUserDefaults().setBool(true, forKey: "contactsAllowed")
case .Denied:
print("Denied")
NSUserDefaults.standardUserDefaults().setBool(false, forKey: "contactsAllowed")
case .NotDetermined:
print("Not Determined")
case .Restricted:
print("Restricted")
}
The app never prompts to allow access to contacts, neither can I select it in System Preferences (it does not show up).
Has anyone any idea how to acccess them on Mac (on iOS it works well)?

Answer 1

Any call to instance of CNContactStore should trigger request. If not try
Reboot (actually this helped me; I was granted access)
Turn on sandboxing
Resetprivacy settings "sudo tccutil reset AddressBook"
Call it on main thread
Instance of CNContactStore call:
[[CNContactStore alloc] init];
Privacy
Users can grant or deny access to contact data on a per-application
basis. Any call to CNContactStore will block the application while the
user is being asked to grant or deny access. Note that the user is
prompted only the first time access is requested; any subsequent
CNContactStore calls use the existing permissions. To avoid having
your app’s UI main thread block for this access, you can use either
the asynchronous method [CNContactStore
requestAccessForEntityType:CNEntityTypeContacts completionHandler:] or
dispatch your CNContactStore usage to a background thread.

Are you trying this from the playground? This won't work.
Try this method in your project:
func getContactImage(name:String) -> NSImage?
{
let store = CNContactStore()
do
{
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingName(name), keysToFetch:[CNContactImageDataKey])
if contacts.count > 0
{
if let image = contact[0].imageData
{
return NSImage.init(data: image)
}
}
}
catch
{
}
return nil
}
Anyway your question led me on the path to find a way to get the contacts image, so thanks for that.
