Question

I’m trying to integrate an additional ampp class file XMPPPubSub class from XMPP framework to my application. It says that we have to enable ARC for these files.

I have added -fobjc-arc flag against the file in Build Phases-> Compile Sources.
The class has this code in it

#if ! __has_feature(objc_arc)
#warning This file must be compiled with ARC. Use -fobjc-arc flag (or convert project to    ARC).
#endif

Even then i get this error

cc1obj: error: unrecognized command line option "-fobjc-arc"

I have seen these links already

1) How to require ARC in a class?

2) How to add ARC for specific file?

3) How to enable ARC for a single file

But yet no luck. Am i missing something here?

Please give some suggestions

Possibly your project is set to use the wrong compiler. In your project settings, check that you are using Apple LLVM Compiler and not LLVM GCC.
