W--iPhone apps with a deployment target lower than 4.3 should include an armv6 architecture (current IPHONEOS_DEPLOYMENT_TARGET = "3.0", ARCHS = "armv7").

Add armv6 and armv7

E--xcode the current deployment target does not support automated __weak references

__weak references only work on iOS 5 and above. If you have the deployment target set to anything earlier, then you'll get the error. Basically, if you want to deploy to earlier devices you can't use automated __weak references. The substitute would be __ unsafe_unretained

Sollution is---

In the Project Navigator, select your Xcode Project file. This will show you the project settings as well as the targets in the project. Look in the "Copy Bundle Resources" Build Phase. You should find the offending files in that list twice. Delete the duplicate reference.

Xcode is complaining that you are trying to bundle the same file with your application two times.
