привет Я работаю над приложением, которое будет отображать существующего пользователя в пределах 50 миль от местоположения текущего пользователя, использующего приложение.
У меня уже есть базовая страница регистрации, на которой хранится имя пользователя иэлектронная почта в базе данных fire, но мой вопрос: как мне узнать текущее местоположение пользователя, который регистрируется для сохранения в базе данных firebase?
вот мой код для страницы регистрации:
import Foundation
import UIKit
import Firebase

Я действительно новичок в swift, поэтому любая помощь будет потрясающей!
Заранее спасибо :))
