Accessibility labels should not contain the type of the control, that's a job for the accessibility trait instead. If you have a button with a label like "Close button" and the ".button" trait, VoiceOver will say: "Close button, button".
Images can automatically scale for accessibility content size categories, by setting the adjustsImageSizeForAccessibilityContentSizeCategory property to true, for any UIImageView you'd like to get its size adjusted. https://developer.apple.com/documentation/uikit/uiaccessibilitycontentsizecategoryimageadjusting/adjustsimagesizeforaccessibilitycontentsizecategory
Hacks are accessibility’s worst enemy. An example. There is a ‘trick’ floating on the internet: if you want a button with an icon to the right of the text, set the semantic content attribute to force right to left. Great way to create focus traps.
