Be careful if you're using Cordova iOS 4.5.0, an error of this kind may happen

duplicate symbol _OBJC_METACLASS_$_CDVLogger in:
   /Users/toto/Library/Developer/Xcode/DerivedData/imp-hkzujazvkracgugyxunzwnzpeiqx/Build/Intermediates/imp.build/Debug-iphoneos/imp.build/Objects-normal/armv7/CDVLogger.o
   /Users/toto/Library/Developer/Xcode/DerivedData/imp-hkzujazvkracgugyxunzwnzpeiqx/Build/Products/Debug-iphoneos/libCordova.a(CDVLogger.o)

ld: 2 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

It can be due to the use of cordova-plugin-console, which is not useful anymore in Cordova iOS 4.5.0 (and breaks the build too!).

To fix it

cordova plugin remove cordova-plugin-console
