Pure-Haxe interfaces don't work

[zeen]

The generated Xcode project fails to build (even without actually implementing the interface, just defining it breaks things):

import objc.foundation.NSDictionary;
import ios.ui.UIApplicationMain;
import ios.ui.UIApplicationDelegate;
import ios.ui.UIResponder;
import ios.ui.UIApplication;
import ios.ui.UIWindow;

interface MyInterface {}
class MyClass /*implements MyInterface*/ {
    public function new() { trace("New!"); }
}

class InterfaceTest extends UIResponder implements UIApplicationDelegate {

    public static function test() {
        trace("Before");
        var v = new MyClass();
        trace("After");
    }

    public static function main() { return new UIApplicationMain ( InterfaceTest ); }
    public static function unusedMain(){}
    public var window :UIWindow;
    public function application(application:UIApplication, didFinishLaunchingWithOptions:NSDictionary) :Bool {
        test();
        return true;
    }
    public function applicationDidBecomeActive(application:UIApplication) :Void {}
    public function applicationWillResignActive(application:UIApplication) :Void {}
}
