I have same issue. Xcode Version 12.4 (12D4e), no devices connected, just closing an open file from IDE takes few seconds, and beachball is shown. Xcode 11.7 had no such issue, nor Xcode 12.3. I have 32GB ram so it is not caused with swap or anything like that. Running on Bir Sur 11.1.

That port number might be a problem. http://localhost:5000/ios/hola?hola=hola -> http://localhost/ios/hola?hola=hola

it is still happening in 14.3.1 and also 15 beta 2. Resolving package graph on slower internet is full of errors about unresolved dependencies. But yes, it works on 1GB fiber optic connection.. :( This part of package resolving process is clearly not ideal/finished.

Well, checking on Xcode Version 15.0 (15A240d), and behavior is like this: I see this in the log: #FactoryInstall Unable to query results, error: 5 Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder -you have to have patience if you have enabled breakpoints and active debug session, because you need to pass 12 exceptions -if you are lucky and xcode does not freeze, you will eventually hear the sound. So the best at the moment is to switch off breakpoints for "Swift Error" (delete it from list of breakpoints) Not ideal, but it works for now. I filled the bug report.

The hack with .plist file I saw in one of the apple's examples. I was wondering how they did it. Unfortunately it is not usable for any other md files. It is good for readme.md only.

After last fiasco in Windows world (CrowdStrike) I would say that adding anything "Anti virus" is just adding another vector of attack to your system. Install apps from trusted sources only and you should be fine.

Only properties that are referenced in view and "registered" are accessed. From my experience it makes sense to add ObservationIgnored when you as a programmer really don't want that property to be tracked by view by error.

for iOS..use it..it is mostly fine, but for macOS...not so much. constant performance problems. New OS release == new problems.

from macOS Sequoia 15.1 RC Release Notes Resolved Issues Fixed: Back-deploying apps that link QuickLookUI to macOS 11 or earlier might crash. (133213738) (FB14667312) So re-compile with Xcode 16 + macOS 15.1..and it should work

Yes, I basically had same question. Why it is missing from Mac? What happens if iPad app is running on MacOS? Why when both devices have required HW you are introducing such SW limitations?

Local LLMs with LM Studio works in Xcode 26 beta 1 on UTM virtual machine with Tahoe installed. ChatGPT does not work as on VM you are unable to setup Apple Intelligence. I got quite a few crashes as well. Overall, this has huge potential.
