Answer 1

Check if your project links libCordova.a (in my case Xcode forgot about the reference, when moving CordovaLib.xcodeproj to another location).

• select your project in the Project Navigator
• go to the Summary tab
• drag CordovaLib.xcodeproj > Products > libCordova.a to Linked Frameworks and Libraries

Clean & build.

Answer 2

Please check your ViewController.m file and goto to 1. Build phase in xcode 2. Select Compile Sources 3. Press + button to add .m/.mm file

I think it will run successfully now

Answer 3

Remove armv7s from your build settings, for both your project and the referenced subproject Cordova. Set your target to 4.3.

Answer 4

I had a similar issue. Somehow my the NSManagedObject Sub-classes of my Core Data entities were in the Compile Sources table twice. The compiler would choke when it hit the first of these duplicates.

I just went into the Compile Sources table and deleted the second occurrence of each .m listing.
