How to hide symbols of iPhone app binary?

Question

I checked several IPAs downloaded from the App Store by running `strings'. None of them shows meaningful symbol.

But the binary I built in the release mode shows all the symbol names in the strings output.

Answer 1

In your Project Build Settings, set Strip Debug Symbols During Copy to YES for Release. That's the default.

If that doesn't work, try toggling these build settings:

• Symbols Hidden by Default
• Strip Linked Product
