Debugging on iOS 15 is terribly slow in Xcode

I'm using Xcode 12 with iPhone 12 Pro. Everything worked fine on iOS 14. But after I updated my device to iOS 15 I’m getting the app's splash screen for more than a minute every time I build the app.

I've also tried to use Xcode 13 with the iOS 15 device, and it also seems to be broken! 

Moreover, when I use a breakpoint and it stops I need to wait for 30-50 seconds to step over or to continue program execution.

Does anyone have these problems too?

Hi yuraist,

You are not alone. I am seeing the exact same issues with Xcode 13 and a iOS 15 device (iPhone X). The launching of app is extremely painfully slow, and debugging is slow as well. Please see my similar question here

My app starts fine, but if I stop on a breakpoint, the first load of the left panel (variables) takes a long time - about 10 seconds on a new MBPro. Once it's loaded things seem okay. Well I have other issues, like variables that I can't see or print, but that's not a speed issue.
