Swift Using Contacts Framework, search using Identifier to match - swift

Question

Trying unsuccessfully to get a contact match providing contact Identifier. I desire to return contact, then to use the image associated with it. I am getting a nil match. thank you. This code I got from a demo, I'm kinda new to programming
import Contacts
var contact = CNContact()
var contactStore = CNContactStore()
let foundContact = getContactFromID("94AAD3B1-E9E1-48C9-A796-F7EC1014230A")
func getContactFromID(contactID: String) -> CNContact {
AppDelegate.getAppDelegate().requestForAccess { (accessGranted) -> Void in
if accessGranted {
let predicate = CNContact.predicateForContactsWithIdentifiers([contactID])
let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactEmailAddressesKey, CNContactPhoneNumbersKey, CNContactImageDataKey, CNContactImageDataAvailableKey]
var contacts = [CNContact]()
var message: String!
let contactsStore = AppDelegate.getAppDelegate().contactStore
do {
contacts = try contactsStore.unifiedContactsMatchingPredicate(predicate, keysToFetch: keys)
if contacts.count == 0 {
message = "No contacts were found matching the given name."
}
}
catch {
message = "Unable to fetch contacts."
}
if message != nil {
dispatch_async(dispatch_get_main_queue(), { () -> Void in
Utility.showAlert(nil, message: message)
})
} else {
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.contact = contacts[0]
print("self.contact: \(self.contact)")
})
}
}
}
return self.contact
}

I solved it :), I removed the dispatch_async stuff, works now: here is fixed code.
func getContactFromID(contactID: String) -> CNContact {
AppDelegate.getAppDelegate().requestForAccess { (accessGranted) -> Void in
if accessGranted {
let predicate = CNContact.predicateForContactsWithIdentifiers([contactID])
let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactEmailAddressesKey, CNContactPhoneNumbersKey, CNContactImageDataKey, CNContactImageDataAvailableKey]
var contacts = [CNContact]()
var message: String!
let contactsStore = AppDelegate.getAppDelegate().contactStore
do {
contacts = try contactsStore.unifiedContactsMatchingPredicate(predicate, keysToFetch: keys)
if contacts.count == 0 {
message = "No contacts were found matching the given name."
}
}
catch {
message = "Unable to fetch contacts."
}
self.contact = contacts[0]
}
}
return self.contact
}
