Issue Summary
Hi all,
I'm working on an Intents Extension for my app, however when I try to run an intent, Xcode pops up the following error:
Could not attach to pid: "965"
attach failed (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.)
An image of the error:
This only happens when I try debugging the Intent Extension. Running the main app target or another extension target (e.g. notifications) doesn't produce this error.
Build Setup
Here are the details of my build setup:
- Mac Mini M1
- Xcode 13
- Building to iPhone 11 Pro Max, iOS 15.0.2. I've also tried building to my iPad Pro 12.9 w/ iOS 15.1 and hit the same issue.
Things I've tried:
- Make sure "Debug executable" is unchecked in the scheme
- I've tried changing the Launch setting to "Automatic" and "Wait for the executable to be launched"
- I've made sure to run
sudo DevToolsSecurity -enable
on my mac - Rebooted iPhone devices + mac mini
- Uninstalled / reinstalled the app
- Deleted derived data
- Removing / reinstalling the development certs in my keychain --> this actually seemed to work initially, but then the problem came back and now it doesn't work anymore.
Console Logs
I've looked at the console logs while this error occurs to see if it can shed light on the issue. Here are the ones that seemed notable to me.
These logs seem to show that Siri is trying to save / write to a file that it does not have access too. Seems very suspicious

Looking for "debugserver" entries, like the error suggests, shows these logs:

I've also attached the full details of the error below via a text file if it helps.
Any help with this issue would be great, and I'm happy to provide more information if needed. Thanks in advance!
