By its name, I misunderstood what shouldGroupAccessibilityChildren does the first time I saw it. It can be used for VoiceOver to traverse all items in a view before moving to the next one, instead of grouping as in combining those elements. VoiceOver traverses elements in the natural reading order, from left to right, top to bottom, in left-to-right languages. Sometimes data is displayed in columns, so that order might not be the most logical one. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/shouldgroupaccessibilitychildren
