UIApplicationMain issue

Hi all, i'm trying xcode 8 and swift 3 with one of my apps. I have an own main.swift file that works on swift 2.3.

My main.swift file looks like this:

UIApplicationMain(Process.argc, Process.unsafeArgv, nil, NSStringFromClass(AppDelegate))

The problem now is that Process.unsafeArgv has changed and it's declaration is:

public static var unsafeArgv: UnsafeMutablePointer<UnsafeMutablePointer<Int8>?>

And the declaration of UIApplicationMain is not expecting an optional value for argv parameter:

public func UIApplicationMain(_ argc: Int32, _ argv: UnsafeMutablePointer<UnsafeMutablePointer<Int8>>!, _ principalClassName: String?, _ delegateClassName: String?) -> Int32

Any help to fix this is welcome

Thanks!!
