Debugger breakpoints not hitting since updating to macOS 26.1

Hi,

I have started facing an issue with Xcode since updating to macOS 26.1. The debugger is not stopping at breakpoints in Objective-C code, however breakpoints in Swift file are working fine. I am using Xcode 16.4.

For breakpoints in Objective-C files I have started to get this message since the OS update - 'Xcode won't pause at this breakpoint because it has not been resolved.' I have already tried cleaning derived data and build folder.

I do not want to upgrade to Xcode 26. Could someone help with the fix?

Thanks
