I started with the custom workout example from Apple. I was able to load the apps from my mac (xcode) to my iphone. I can run the apps on my iphone. I completed the authorization and reviewed the workout. I then uploaded the workout to the watch and it appeared to work. It never showed up on the watch. I tried restarting the watch and iPhone. I have. a second watch and I tried that. Nothing helped. IPhone 14 with ios 18.2. Watch is Series 6 with watch OS 11.2. I also tried it with the watch on the charger but no change. Workout Kit seems like a good idea, but not if you cannot get it on your watch. It seems very few people are using it as there is little info online.
