Breakpoints Don't Get Into Xcode 7

Question

I have an Xcode project that includes a sub-project. After upgrading to Xcode 7, the breakpoints in the subproject were not affected, and I cannot enter the subproject function calls. Some breakpoints hit, but they just show the assembly to call, so it seems that the subproject is not showing correctly. I checked all the usual things, that is, it generates debugging symbols, configuration assembly during debugging is not an issue, and such things are shown in the settings of the Xcode project. Anything else I can skip? In Xcode 6.4, this was not a problem.

Answer 1

This was a problem with the lack of the correct debugging information format specified in the hosting project. I decided by creating a dummy / test Xcode project and comparing the debug file format described in detail for each configuration with the fact that the project has a problem that changes the format of the debug information in accordance with the dummy / test project project.
