# init(coordinate:addressDictionary:) Creates and returns a placemark object using the specified coordinate and Address Book dictionary. ``` init(coordinate: CLLocationCoordinate2D, addressDictionary: [String : Any]?) ``` ## Parameters `coordinate` The geographic coordinate to associate with the placemark. `addressDictionary` A dictionary containing keys and values from an Address Book record. For a list of strings that you can use for the keys of this dictionary, see the “Address Property” constants in `ABPerson`. All of the keys in should be at the top level of the dictionary. ## Return Value An initialized `MKPlacemark` object. ## Discussion You can create placemark objects manually for entities for which you already have address information, such as contacts in the Address Book. Creating a placemark object explicitly avoids the need to query the reverse geocoder object for the same information. ## See Also [Location and Maps Programming Guide](https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/LocationAwarenessPG/Introduction/Introduction.html#//apple_ref/doc/uid/TP40009497) --- Copyright © 2026 Apple Inc.
