FWIW, I'm on Xcode 12.0.1 on Catalina 15.7 and I'm having Xcode crash as soon as I try to unpair my iPhone XS Max. App runs fine in simulator. iPhone is running latest 14 release. I also have Xcode 12.2 beta 3 thinking that might be resolved, but same problem. Phone is up to date, as is MacOS for released version.

Still happening to me as well, I started process earlier at notification. I got to about 3gb before the installation failed. Even after the status page is updated, I'm getting this now when attempting and have rebooted since. "Installation failed (next line) An error occurred while installing the selected updates." (just wanted to add, I'm on a late 2014 5k imac which I checked is supported, and I've got 172 gb of free space on the Macintosh HD)

I'm curious about this as well. I have a certain count of a variable I know will need disclosure groups on a per view basis. However, I can't create a variable for it in the struct since it's only available in the body. I'm a bit of a newbie to swift so could just be doing things wrong, but this seems overly difficult. I want each disclosure group to expand separately from the others, so thought I might just be able to make an array of Bools in an array for each entry that will have a disclosure group. Didn't work. I can do one that applies globally to all items in one disclosure group very easily of course, and that's what I'll do until I can get a better aesthetic fix.
