In the menu bar, go to Build > Build Results and post back what you see (screenshot and/or full text).

This line in the build transcript is causing the problem

-I/Users/mikezang/iPad/MyApp/Persistence/build/Persistence.build/Debug-iphonesimulator/Persistence.build/DerivedSources ? filePath

Derived sources are things like lex/yacc where a file is generated by a tool as part of the build and then compiled by the C-language compiler. I don't understand how the "? filePath" has gotten into this -I line.

I would look at that path and see if there's a file or folder there. I'd probably delete the build folder and try again. Are there any Derived sources in this project, like lex/yacc or anything else besides .m, .h?

One other thing, it might be possible to end up with something like this if you've pasted something by mistake into a framework search path or one of the other project settings. I would look over the target settings to see if anything looks wrong.

While a -I like that seems like a bug of course it isn't a common bug. At the least if Xcode thinks there is something named "? filePath" it ought to quote it.

Well, you can check my build result and I also upload my project, I hope I can get right result.
