Apple News – Update your application

Apps must accurately describe new features and product changes in their "What's New" text. Simple bug fixes, security updates, and performance enhancements may rely on a generic description, but more significant changes must be listed in the notes.

About this Apple is written in the official guide, paragraph 2.3.12: developer.apple.com/app-store/review/guidelines/#accurate-metadata Update game and application for IOS in App Store Details description Apple guide

var test: Int {
get {
return x
set (newVal){
x = newVal

let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 20, left: 10, bottom: 10, right: 10)
