Cannot find protocol declaration for 'ABPeoplePickerNavigationControllerDelegate' - ios

Question

In a Project having already ObjC, I'm adding a Swift Class
import AddressBookUI
class MyVC : UITableViewController, ABPeoplePickerNavigationControllerDelegate {
}
MyApp-Swift.h:289:42: Cannot find protocol declaration for 'ABPeoplePickerNavigationControllerDelegate'; did you mean 'UINavigationControllerDelegate'?
No, Swift, I really mean ABPeoplePickerNavigationControllerDelegate. Really wondering what I am doing wrong here...

Answer 1

FWIW, the reason this works with ABRecord in pure Swift, but not in the Objective-C compatibility header is that there is a typealias which the latter apparently doesn't translate back correctly:
typealias ABRecordRef = ABRecord
see https://developer.apple.com/library/prerelease/ios/documentation/AddressBook/Reference/ABRecordRef_iPhoneOS/index.html#//apple_ref/c/tdef/ABRecordRef
Might be worth filing a Radar 📡

Answer 2

I need to add
#import <AddressBookUI/AddressBookUI.h>
in my Briding-Header.h. One could think the import in my Swift file was enough. It was not.
That said, now I have a new problem when implementing
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!, didSelectPerson person: ABRecord!, property: ABPropertyID, identifier: ABMultiValueIdentifier) {
}
Here comes the next error:
-Swift.h:297:110: Expected a type
It has a problem with the ABRecord type in
didSelectPerson:(ABRecord)
Doesn't help if I also import AddressBook in Briding Header or Swift File.

Answer 3

You can check the code I've used here
Pure Swift project, no Objective-C involved
For me, this is compiling fine without using any Bridging-Header
import UIKit
import AddressBook
import AddressBookUI
class ViewController: UITableViewController, ABPeoplePickerNavigationControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!, didSelectPerson person: ABRecord!, property: ABPropertyID, identifier: ABMultiValueIdentifier) {
}
}
I'm adding relevant frameworks (AddressBook, AddressBookUI) to the link binary with libraries phase of my target
Objective-C Project, with Bridging Header
My Bridging-Header.h:
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
make sure your Bridging-Header is properly referenced in your target
swift VC code is the same as above

Fixed my second Problem thanks to #neonacho on Twitter. Instead of ABRecord I had to use ABRecordRef to compile. Not sure why Diego's code works and not mine. So it became
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!,
didSelectPerson person: ABRecordRef!, property: ABPropertyID, identifier: ABMultiValueIdentifier) {
}
and it works.
