Xcode: Undefined symbols for architecture arm64 error

Question

In my Xcode 5 project I use RestKit for REST communication. Everything works fine with the simulators, but generating the ipa file, I get the following error:

ld: warning: ignoring file /Users/joseph/Library/Developer/Xcode/DerivedData/XXXXXXXXXX-gdwdekevxtdfivfpsnmyykeqhulk/Build/Products/Debug-iphoneos/libRestKit.a, missing required architecture arm64 in file /Users/joseph/Library/Developer/Xcode/DerivedData/XXXXXXXXXXXXX-gdwdekevxtdfivfpsnmyykeqhulk/Build/Products/Debug-iphoneos/libRestKit.a (2 slices)

If in RestKit project, I change in "Build Settings" -> "Architectures" the "Standard architectures (ARMv7, armv7s)" by Standard architectures (including 64-bit) (ARMv7, armv7s, arm64) option, everything compiles fine . Is this correct?, Does not bring any result, I have to change some other settings.

Did you try changing in **your** project and in **RestKit** "Build Settings" -> "Architectures" to "Standard architectures (ARMv7, armv7s)"? — Refael.S, Jan 04 '14 at 21:26
I change in my project and in RestKit to "Standard architectures (including 64-bit) (ARMv7, armv7s, arm64)". — Jose Rodriguez, Jan 04 '14 at 22:02
So whats the question? you build succeeds but archive doesn't? — Refael.S, Jan 04 '14 at 22:08
My question is, if it brings no disadvantages or if I have to add some other configuration. Because RestKit has by default"Standard architectures (ARMv7, armv7s)" on "Build Settings" -> "Architectures". — Jose Rodriguez, Jan 04 '14 at 22:30

It just means you are building your project also for 64bit (iPhone 5s) and nothing to worry about, see this link for some more explanations: Xcode 5 and iOS 7: Architecture and Valid architectures

Just change in RestKit project -> Build Settings -> Architectures to Standard Architecture (armv7, armv7s, arm64). After that everything should work.

This worked for me:

ios sdk 9.3

into your build setting of app.xcodeproj valid architecture: armv7 armv7s Build Active architecture : No

Clean and build , worked for me.

I ran into the same/similar issue implementing AVPictureInPictureController and the issue was that I wasn't linking the AVKit framework in my project.

The error message was:

Undefined symbols for architecture armv7:

"_OBJC_CLASS_$_AVPictureInPictureController", 
referenced from:
   objc-class-ref in yourTarget.a(yourObject.o)
ld: symbol(s) not found for architecture armv7

clang: error: linker command failed with exit code 1 (use -v to see invocation) The Solution:

Go to your Project Select your Target Then, go to Build Phases Open Link Binary With Libraries Finally, just add + the AVKit framework / any other framework. Hopefully this helps someone else running into a similar issue I had.
