Xcode 5 and phonegap: linker errors on building for device but not for simulator

Question

Our phonegap app builds fine for the iphone simulator but generates linker errors when building the app on an iphone. the only thing that changed was installing testflight and a test app.

We already removed testflight and the test app, but the linker errors remain.

Any ideas on how to fix this?

We're on xcode 5 and phonegap 3.4.

Errors:

Answer 1

This kind of problems occur while updating your Xcode but any third party tool you are using may not be updated with this architecture armv64.

So Click on your Project Navigator from XCode.

Click On Targets from your Project and click on BuildSettings from it.

Find Valid Architectures in it.

Just double click on that and remove armv64 from that.

Make sure there is armv7 and armv7s only.

In my case this worked for me.

Clean and build your project. It should work fine now.

Hope it helps you.

EDIT

Now, as of Feb 1st 2015, apple will not allow apps without arm64 architecture supported.

So make sure that all the apps submitted have arm64 support.
