You can create your own accessibility elements from scratch. One use-case for doing that is when you do some custom drawing instead of building your UI using or relying on UIKit components. A circular progress bar, could be an example.
Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:
Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

Sometimes, you may want to create a custom component, even if there is a similar one in UIKit because you want to style it in a way that the default one won't let you. That's fine, just take into account that you'll need to make it accessible.
If an image does not convey additional information, maybe it's just used to make the UI look more attractive, it makes sense for VoiceOver to skip it. UIKit: set isAccessibilityElement to false. SwiftUI: create a decorative image explicitly.
If you need for a view (and all its subviews) not to be focusable by assistive tech like VoiceOver, you can set its accessibilityElementsHidden property to true. This isn't needed very often, but it can be useful for certain custom experiences.
