Xcode: build failed: error message

Question

I am building and running my Xcode app but I get a build failed message on account of the following error message:

Undefined symbols for architecture x86_64:

      objc-class-ref in AppDelegate.o

      -[AppDelegate dealloc] in AppDelegate.o
ld: symbol(s) not found for architecture x86_64

How do I resolve this/these issue(s)?

I would set Architectures in your project to $(ARCHS_STANDARD_32_BIT), which will do the right thing for both iOS builds and OS X / simulator builds.

The problem is that your library is not built for x86_64, but your project is trying to build for both i386 and x86_64, so the link step fails. Apple changed the default architecture in Xcode 5.1 to include 64-bit architectures.

See these other questions for more info:

Click on your project in xcode and go to build settings -> valid architectures and remove arm64 also change Standard Architectures to armv7 and armv7s .Clean and rerun the project

It looks like you need to include the Salesforce Mobile SDK iOS framework in your project.
