There are clear iOS guidelines for creating accessibility labels. For example, the label "should begin with a capital word and not end with a period."
The UITextField
text input control includes the option for placeholder text that is displayed faintly when the field is empty. I haven't found guidelines for this placeholder text except for:
Display a hint in the text field if it helps users understand its purpose. A text field can display placeholder text—such as Name (or Address)—when there is no other text in the field.
As a rule of thumb, does it makes sense to apply the guidelines for accessibility labels to placeholder text also? Are there guidelines for placeholder text?
accessibilityHint
which is different from theplaceholder
property or "placeholder text". [Apple describes what is the accessibilityHint here)[developer.apple.com/library/content/documentation/…). Use "placeholder text" instead/only.
