When I was user testing, my test subjects would often have typos (which is fine), then iOS's usual "spell check" pops up with the right word intended, and I found people clicking it to implement what they want, however, on clicking it, it closes it out. They then let out a sigh of frustration.
I found myself doing that too, and often, even though I know tapping it will close it out and "ignore" the change. The change happens only if you continue typing (which also makes it frustrating for me when I'm speaking another language through text. It auto corrects my correctly typed word).
So my question: Does anyone know what was their reason behind implementing this even though it seems contrary to what they were trying to do? (Note: Maybe this was what they were trying to do, and if so, what was their findings?)
