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?

  • 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.

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
