No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386).

Waiting for response.

I was facing same issue, I just Replace the Twitter Library with new Library that support arm64.

Please download the updated library from https://github.com/bengottlieb/Twitter-OAuth-iPhone/tree/master/Twitter%2BOAuth

and one more thing update library path on Buid Settings -> Library Search Path very carefully

Remember me in your prayers :)

Go to Build Settings --->Architectures--->Build Active Architectures only--->Release -->NO
