I have a problem with that error :

Undefined symbols for architecture i386:

When I build and go, it run successfully on the simulator but not on the device, I try a simple new project, I try to run it on the device, it was ok, but this project didn't run because of that error, the full stack error is this :

I changed the build mode, so I have choosed the device(in my case i use an iPod 4.3.5), now I have an other error :

'FavoriteCities.app' was built for 'i386', but the device 'iPod (Imac)' requires 'armv7' or compatible architecture.

FavoriteCities is my application name, please help me to figure out what could be the problem causing all that.


You need to change build architecture for device builds. It should have been armv6/7 by default for iOS app, but I guess you or something you did messed those settings up.

(In Xcode 4) select your project, go to Build Settings tab and make sure it looks like this:
