Make sure you support Dynamic Type up to the largest text size available. Take into account that there are five extra accessibility sizes available from the Accessibility Settings. It can make a huge difference for lots of users.

When working with Dynamic Type, I find it useful to remember that sizes for the different text styles won't scale linearly, nor will they do proportionally between them. For larger dynamic type sizes, styles will come closer together in size.

Love this feature! Yahoo released the possibility to explore charts with audio, in the finance app, when using screen readers in 2019. You can do now something very similar since iOS 15. https://coolblindtech.com/yahoo-finance-app-makes-charts-accessible-to-blind-and-partially-sighted-users/ You can move your finger in the x-axes, and it will play a sound with a different pitch depending on the data in the y-axes, making it easier to identify trends in the graphs. You need to conform to the AXChart protocol by implementing the accessibilityChartDescriptor property.

Potential benefits from grouping logical pieces of information and moving buttons to custom actions: reduce redundancy (by removing repetitive controls) and reduce cognitive load (by making easier to know what item will be affected by each action)
