Determining iOS Signal Strength

Question

Is there a way to determine the signal strength of an iOS device?

I found this: iOS Get Signal Strength in Swift (Core Telephony)

But there didn't seem to be a solution here. Has an API been written for this?

Keep in mind, I need the solution to be valid for sale on the app store so it can't use any private libraries.

take a look at this: #14604773 - it is possible to call objective-c code from swift, as long as you set up the appropriate bridging headers and import the header file of your objective-c method: #import "MyObjectiveCCode.h" – Ariose

This might sound stupid but I've never written any Objective-C code. Will I need to create a header and main file for the class? – Sherrer
