问题
When having an element on screen that has the UIAccessibilityTrait .adjustable, Voice Over reads out the automatic hint provided by iOS, saying "swipe up or down with one finger to adjust the value".
How do I stop iOS from saying that hint? I want voice over to only read my own accessibility hint.

When you use an accessibility element whose trait is .adjustable, the system will automatically read out its hint and it's not possible to remove only this one and let yours spoken as you wish.
However, the user can specify to stop listening to ALL hints in his settings (iOS 12: Settings - General - Accessibility - VoiceOver - Verbosity - Speak Hints):
When you deal with the system hint, it's all or nothing unfortunately.
