iOS 11 で追加される CLGeocoder の geocodePostalAddress を試してみました。既存の reverseGeocodeLocation と合わせて、住所と緯度経度とが相互に変換できるようになりそうです。

コード

//: Playground - noun: a place where people can play

import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true

import UIKit
import CoreLocation // CLLocation, CLGeocoder
import Contacts // CNPostalAddress

// lat_long -> address

var cur = CLLocation(latitude: 35.66, longitude:139.75);

CLGeocoder().reverseGeocodeLocation(cur, completionHandler:
    {(placemarks, error) -> Void in
        if((error) != nil){
            print("Error", error!)
        }
        if let placemark = placemarks?.first {
            print("State:       \(placemark.administrativeArea!)")
            print("City:        \(placemark.locality!)")
            print("SubLocality: \(placemark.subLocality!)")
        }
})

// address -> lat_long

var postal = CNMutablePostalAddress()
postal.state = "Tokyo"
postal.city = "Minato"
postal.subLocality = "Shibadaimon"

CLGeocoder().geocodePostalAddress(postal, completionHandler: {(placemarks, error) -> Void in
    if((error) != nil){
        print("Error", error!)
    }
    if let placemark = placemarks?.first {
        print("latitude:    \(placemark.location!.coordinate.latitude)")
        print("longitude:   \(placemark.location!.coordinate.longitude)")
    }
})

playground での実行結果

State:       Tokyo
City:        Minato
SubLocality: Shibakoen
latitude:    35.6600347
longitude:   139.7538893
