How to get current location of the phone in your iOS App? – Xcode tutorial

This video shows the steps to create your iOS App which can access the current location of your phone. The location coordinates is fetched in locationManager using CLLocation services of the phone.

The location coordinates once received is updated in the Map and also updated in the Labels widgets in the App’s layout.

Also, please note, the info.plist file should be updated with the below 2 keys to get the access of the location:

NSLocationWhenInUseUsageDescription
(Privacy – Location When In Usage Description)

NSLocationAlwaysUsageDescription
(Privacy – Location Always Usage Description)

For the value part you can input anything. For example: “This App will access your Location.”
