I just created one new cordova ios project via CLI, and i opened that project in Xcode 7.1 and while running on simulator am getting some error on mainViewController.xib, if
I have the same problem. The only way I have found to get round this is to update the target 'Deployment Target' to 8.1 and also the CordovaLib project 'Deployment Target' to 8.1 this allows the app to build and run without the MainViewController error. However this is not a great solution as I assume it no longer supports devices with ios 7.1 installed.
