I have a UITextview. It has enough text in it that it flows into multiple lines. However when I run the app on a device, the text does not flow onto subsequent lines, it's as if the text is carrying on beyond the bounds of the view.
All the settings for the view are the default, but user interaction is disabled. The view has constraints which bound it to the margins of the viewport. I've coloured the background of the view to check this - the view is not running off the edge of the viewport, and has sufficient height that the 2nd and 3rd lines of text should fit on the view, but below the first line of text the view is empty.
What is going on?
