Best Possible way to add instagram like layout guide with UIPinchGestureRecognizer UIRotationGestureRecognizer & UIPanGestureRecognizer?

I have used UIPinchGestureRecognizer UIPanGestureRecognizer & UIRotationGestureRecognizer with UILabel to achieve instagram like zoom and drag functionality but now i would like to show layout guid like when UILabel is drag in center it will show layout guid like below example which is example of instagram. It will also display layout guid when you rotate UILabel

What is the best and accurate possible way to achieve this functionality.

This is What i have already done

Here is code i have done for simple drag and zoom functionality.

SnapGesture Class

import UIKit

/*
 usage:

    add gesture:
        yourObjToStoreMe.snapGesture = SnapGesture(view: your_view)
    remove gesture:
        yourObjToStoreMe.snapGesture = nil
    disable gesture:
        yourObjToStoreMe.snapGesture.isGestureEnabled = false
    advanced usage:
        view to receive gesture(usually superview) is different from view to be transformed,
        thus you can zoom the view even if it is too small to be touched.
        yourObjToStoreMe.snapGesture = SnapGesture(transformView: your_view_to_transform, gestureView: your_view_to_recieve_gesture)

Add Gesture in UILabel

// define 
var snapGesture: SnapGesture?

// add gesture
self.snapGesture = SnapGesture(view: self.myLabel!)
