Xcode 5.1 and iOS 7.1 - cannot install app on a specific 5S

This is the most bizarre issue I've ever seen. I have Xcode 5.1 and iOS 7.1 on a iPhone 5S, iOS 7.1 on a iPad Retina and iOS 6.something on an iPhone 4S.

My app builds and installs on the 4S no problem. It builds and installs on the iPad no problem. On my iPhone 5S it crashes and burns on build with tons of warnings and erros. What can possibly cause this? This makes no sense. Previous versions of this app installed to this phone no problem. Those previous versions also no longer install. Test "Hellow World" apps also fail.

Same exact app runs without issue on the other two devices.

Here is the result of a simple "Hello World" test app that runs fine on the other two devices (and the simulator) but crashes and burns on this 5S only.

iPhone 5s, OS X Mavericks (10.9), 16GB

Update: With a different 5S on a different dev Mac also with Xcode 5.1 the errors happen. However on Xcode 5.0.6 there is no issue.

Xcode now enforces previousl hidden warnings.

You didn't show enough of the Linker errors but I'm pretty sure I know what is wrong as this same thing happened to me.

It looks intimidating but those warnings are easily corrected.

You have a third party library that is not 64-bit.

Rebuild your project but change the build setting as show here:

You need to change one thing: ARCHS_STANDARD to ARCHS_STANDARD-32_BIT.

This creates a 32 bit app which will run fine on iOS 7.

Thanks for your answer Michael, this fixed it for me also.

I experienced this same Mach O linker error with libPD, embedding Pure Data. The error only occurred as I tried to Archive my app for submission to the app store. Tripped me up for several hours, very glad this answer is out here!
