I have gone through the Apple documentation and found the solution for this question.

Apple has changed few guidelines to get user location.

Full code for location access in Swift & Objective-C both

Solution:

Now we need to add three Authentication Key into Plist:

NSLocationAlwaysAndWhenInUseUsageDescription
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription

Please ask for the other permission also "When ever in use permission" and add both permission on the plist.

回答3:

I've added both Keys in the info.plist file in order to ask for permissions, however after deleting the app and opened it again the simulator didn't display the alert to permit the user select one option.

I could make the alert appear again after deleting the app, then opening the settings application and finally installing again the app.

Hope it could help somebody.

Please change requestAlwaysAuthorization to whenInUseAuthentication. Then it will start working. I think this might be due to GM Seed/Beta version of xcode. In stable version we might not have this issue.
