I tried to store a new version of my app to Apple Store.
I updated my last version with i-tunes connect by B4I (I have a Windows pc) and then Apple wrote me:
ITMS-90338: Non-public API usage - The app references non-public symbols in ServiceH24: __NSSetLogCStringFunction. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed.
What means?
Someone can help me?
