I have noticed the snap behaviour does not take effect upon first click of the image. It only works on the second click of the same image. I have my snap implementation in the viewDidLoad method

If you notice Sam added that behavior to viewDidAppear.

Hi Amit,

Putting it on viewDidAppear did not solve the above problem too. I am also debugging it. Is it because on first image load, the image file is downloading asynchronously and the snap behaviour can not be implemented with the asynchronous downloaded image. While subsequent click on the same image will have been cached, and the snap behaviour can be applied on the cached image immediately.

Will like your opinion on this.

Thanks
