Questions tagged [debug-symbols]

A debug symbol is information that expresses which programming-language constructs generated a specific piece of machine code in a given executable module.

A debug symbol is information that expresses which programming-language constructs generated a specific piece of machine code in a given executable module. Sometimes the symbolic information is compiled together with the module's binary file, or distributed in a separate file, or simply discarded during the compilation and/or linking. This information enables a person using a symbolic debugger to gain additional information about the binary, such as the names of variables and routines from the original source code. This information can be extremely helpful while trying to investigate and fix a crashing application or any other fault.

Is there a downside to running `strip -S -x` on all frameworks in my macOS binary? If not, how can I automate that process?

I noticed that running strip -S -x (remove all debug and all local symbols) on the binaries in my app's 'Frameworks' folder makes them ~25% smaller, even when I have enabled stripping of debug symbols in my build settings. Also note that this makes…

Swift: how to fully strip internal/inline symbols?

I need to write some license checking code in Swift. I know Swift is not optimal for that kind of code in the first place, as it is harder to obfuscate. But if the code that needs to know whether the app is registered is written in Swift, this is…
