watchOS 3.0 Compatibility

Hi!

When I try to run my app on watchOS I get the following error

dyld: Symbol not found: _OBJC_CLASS_$_CLKComplicationTemplateExtraLargeSimpleImage

However, I do use #available declaration

if #available(watchOS 3.0, *) {
    if family ==  .ExtraLarge {
        let tmpl = CLKComplicationTemplateExtraLargeSimpleImage()
        tmpl.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "complication_plane_large")!)
        entry = CLKComplicationTimelineEntry(date: NSDate(), complicationTemplate: tmpl)
    }
}

How can I have watchOS 2.0 and watchOS 3.0 compatible app if I use CLKComplicationTemplateExtraLargeSimpleImage in code?

Thank you in advance
