Guidance to create a catalogue app

Hello everyone!

I am in the process of creating an iOS app for a catalogue app that I created for Android which you can see it here (https://play.google.com/store/apps/details?id=com.dynmk.bonbonup) or here if you don't have an Android phone (https://appetize.io/app/ctxjvzhu56fjh01dw89urmvq9g)

I want to create an iOS app that is similar to the one I did for Android using JSON files to retrieve the images and info of the product as you can see in the GridView in the Android app. I create the JSON files through a JSON editor online and then upload the files to a webhost file manager in which all images and JSON files are kept.

My experience with Xcode is not too much and I am still in the learning curve by checking the tutorials in tree house and searching through the web.

I have been reading about UICollectionView to create a GridView similar to the one I have in the Android app but my main question would be, will it work with the JSON files I have created?

Any suggestion would be appreciated,
