I'm having the same issue. I have a MacBook Pro 16-inch, 2019 and I'm using macOS Catalina 10.15.7 & Xcode 12.0.1 and as soon the simulator is working (Running the app) the cracking noise starts if ANY sound is coming out of the speakers... Please fix it!

Same problem, and I just started learning to use Xcode...it is not very confidence-inspiring to experience this kind of bug

Same problem on my 2017 15" MBP, basically all sound sources have the crackling sound issue on my mac, on Catalina 10.15.7

I have this problem as well on my 2020 iMac 10 core. It only happens when the Simulator is running. It appears that the simulator is competing with the audio. I have a workaround that might help, however; if you turn the volume of the Simulator all the way down, it may resolve the issue. At least, since doing so I haven't heard it happen.

Same issue here, makes watching tutorials as I code very difficult lol. The issue seems to be inconsistent and can sometimes be fixed with a restart. Any audio coming from any app is extremely distorted while Xcode is open; it starts when I run the preview or simulator in with SwiftUI.

Catalina 10.15.7 same issue still not fixed, it's actually way worst. Unbelievable. User @raymo is actually correct, switching the iOS Simulator, if you are a developer, fixes it for a bit.

I have this problem too, really feel bad.
Restart it and hope the Apple will fix it.

You can restart the coreaudio process manually. This doesn't fix the firmware issue that I just paid $5k for (Great work as always, Apple!) but it does mean you won't have to reboot your computer every time this happens.

Restart coreaudio

Open Activity Monitor
Search for "coreaudio"
Double-click coreaudio
Select Quit
Select Force Quit
coreaudio should restart on its own in a moment or so

Same problem here running Catalina and XCode 12.+.

Restarting the simulator fixes the problem instantly for a while. I have to do this once every so often ... waiting for a more permanent solution from Apple.
