use of unimplemented initializer 'init(contentURL:)

I've got a problem.When i integrated the MobilePlayer(Swift version) into my OC project using Cocoapods. I've also added the MobilePlayer into my Swift-bridge.h file.

Here come's the problem:

when i doing this

MobilePlayerViewController *player = [[MobilePlayerViewController alloc] initWithContentURL:url];

The Xcode warning me that MobilePlayerViewController.swift: fatal error: use of unimplemented initializer 'init(contentURL:)' for class 'MobilePlayer.MobilePlayerViewController' after i run it in simulator.

Had anyone know why? Thx
