I'm trying to create a complication bundle for my app by following these instructions:https://developer.apple.com/library/prerelease/content/releasenotes/WatchKit/AddingComplications/index.html#//apple_ref/doc/uid/TP40017258However, the generated gallery.ckcomplication bundle only contains a single file named complicationManifest.json. That file contains a single key, supported complication families, and the value for the key is an empty dictionary.If I try to save the complication bundle again in the same session, I get this error dialog:Failed to save complication bundle.clockkitutil terminated with an unexpected status: 256 : exited? 1,1 signaled? 0,0 stopped? 0,1My app supports a variety of complication sizes and I'm able to select them when editing a watch face.I've implemented getLocalizableSampleTemplateForComplication: in my ComplicationController and verified it is getting called and generating valid templates (FWIW, all of my templates are image only templates except CLKComplicationFamilyUtilitarianLarge, which contains a non-localized text provider with my app name).I'm assuming I missed a step or have some sort of configuration error with either my watch app target or watch app extension target. Has anyone else run into this? Any ideas on what settings I should check or things I should try?
