Find if user is in a call or not?

Question

I wanted to see if a user was using the application and to see if they were in a phone call or not. I was following this link to see check if a user was in a phone call or not: iOS How to check if currently on phone call. However, this looks like it's for Objective-C. I was wondering if there was a Swift equivalent for this. This is my attempt:

    var currCall = CTCallCenter()
    var call = CTCall()

    for call in currCall.currentCalls{
        if call.callState == CTCallStateConnected{
            println("In call.")
        }
    }

However, it doesn't seem as if call has an attribute .callState like how it does in the previous example. Any help would be appreciated! Thanks!

iOS 10, Swift 3

import CallKit

/**
    Returns whether or not the user is on a phone call
*/
private func isOnPhoneCall() -> Bool {
    for call in CXCallObserver().calls {
        if call.hasEnded == false {
            return true
        }
    }
    return false
}
