A simple phone restart will fix it
I have had to come back to this SO question twice in the past couple weeks. First time, I did have to update my Xcode and iOS versions, which fixed the issue. Now, the issue has returned, but there are no updates. I tried disconnecting and reconnecting my phone from my laptop, but to no avail.
What fixed it the second time was merely restarting my phone. I am curious if that would have fixed it the first time too, without needing to have updated.
I know this is just echoing the other answers here, but at the very least, I would recommend just starting with a simple phone restart and seeing if that fixes your problem. Here is the specific screenshot that I encountered, in case yours is the same (pro tip: you can open up the “Devices and Simulators” window by going to Window -> Devices and Simulators shift-command-2).
