Ionic Version 3 Gestures

Hey Geeks

I was watching a video on youtube on how to use gestures. link

I have fully developed an app on ionic 3 and want to implement this functionality. This is simple and its not that complex. I have tried to implement this using tabs(slide up on another tab) but its not working proper because it gets to using multiple tabs. If gestures on ionic 3 are not really implementable please can i get an update as soon as possible so that i can find another alternative.
