Xcode breakpoints stopped working
I was having a normal working day debugging an UI issue with a working env on Xcode 16.2 on simulator 18.0 iphone pro 16... was able to debug and breakpoints were working fine... after a small UI adjustment in code i re-run the app and breakpoints stopped working "out of the blue".
I already attempted these steps:
1- clean build
2- clean pods
3- clean cache
4- clean derived data
5- clean userdata
6- multiple reboots
7- delete projcet folder and reclone it and install from scratch
8- deleted simulator and recreated and tried on versions (17.5, 18.0, 18.1 and 18.2) that I never used before
9- updated to macOs 15.4
10- deleted my 2 xcode installations (16.2 and 16.0) and installed xcode 16.3 and xcode 16.0 and attempted on both versions with multiple sim versions as well including new 18.4
11- reinstalled xcode tools
12- attempted breakpoint in another project
13- checked all configuration mentioned in stack overflow and all suggestions were already in place. I disabled and re-enabled them to see if that fixed but it didn't. (schema debug checks, code optimization disabled, no show disassembly, etc.)
Only thing that works is symbolic BP like UIViewAlertForUnsatisfiableConstraints this gets triggered but all other "normal" breakpoints are ignored.
I tried starting without breakpoints and adding them on the run. starting with them enabled. etc. etc. all the combos. nothing seems to work.
Please can I get urgent support here?
