Doubled text upon Paste action in Xcode 12 Beta 3?

I'm also seeing this on Xcode 12 Beta 3. It's driving me nuts.

Can confirm this. And it beeps like crazy.

Oh my god, finally somebody else is seeing this! It seems like all keypresses are being duplicated. Often the second one results in the alert beep, but things like CMD-T will open *two* tabs and CMD-W will close *two* tabs. CMD-N to add a new file shows the template chooser but also an alert saying "An assistant session is already running on this window".

What on earth is going on?

Like the original poster, I only see this on Xcode Version 12.0 beta 3 (12A8169g). But I am seeing it on macOS 10.15.6 (19G73).

Hello fellow keystroke doubling Xcode restarting beta users! 👋😄

I'm seeing this happen about 1-2x per hour working with Version 12.0 beta 3 (12A8169g) on 10.15.6. Given the reports so far it seems like it's not correlated with macOS version.

There seems to be some sort of triggering event that puts the entire UI into the keystroke doubling / bell-on-every-keypress failure mode, which I've only been able to remedy w/ a full Xcode restart. I have yet to narrow down the specific steps that produce this state, but I'll continue to squint at this and report back if I stumble on any more information.

I'm experiencing this too. Only fixed by restarting Xcode. Have to do it a handful of times an hour.

For me restarting Xcode didn't seem to fix it. Maybe the trigger happened really quickly for me.

But Xcode 12 beta 4 seems to be fixed for me! I hope so.

Anybody else still getting this with Xcode 13.2.1?
