> for debug, after web searching, i connect my daw(reaper, cubase) and xcode release If you mean you were using 'release' mode for building your plugin then yes, that'd prevent breakpoints from working. ---

XCode 7 seem to have issues in general with C++ BPs. I havent verified with 7.2 yet, but previously it was very unpredictable when and where a BP would actually trigger breaking into the debugger. If somebody knows the cause or has a solution/workaround I would be very happy to learn about that! Cheers, raketa ---

- Make sure you are running a Debug build. - Make absolutely sure you are runnng a Debug build. - Make sure you are in the _plugin's_ Xcode project, the process you are attached to is the _host_, and you actually load the plugin in the host. - Create a file named .lldbinit (with the dot in front) in your home folder, and add this line to it:  settings set target.inline-breakpoint-strategy always ---

first edit target , must select debug( for break point)  and Executable, choose your daw   last  cmd + r and you can debug with break point   thank you all. ---

Thanks, timur, I am pretty sure I am using the debug build for debugging. And I guess that wouldn't explain why it breaks somewhere and certainly not where my BP was. (Previous Xcode versions where picky about mixed line-endings and assigning the BP correctly, but that doesn't seem to be the cause here.) Its not that some optimizations are turned on, creating a bit wired debug experience. Cheers, raketa ---
