Hi thank you for your detailed answer.
i understand and I think that in consequence you must implement the swimming using less metrics than other workout types. The goal is to have a reliable app. If Apple does not deliver some metrics data or deliver them late then you cannot use them reliably.
I think that if we can already have the base metrics that are displayed by the Apple standard exercise app it will be a good start.
makes sense no ?
thanks again,
Fred.

I completely agree with you !
The current plan for swimming is to limit the metrics to the same as the native app and then improve things in the future. As you say, it is best to start simple.
In terms of multi-activity workouts such as triathlons, it would be relatively easy to add a command to start a new separate workout of a configurable type. However I would prefer to associate the separate activities together in the iPhone app as one workout with different sections for each activity. That would be a lot more work, so I will probably start with the separate workouts approach and then extend it afterwards.
However this is just off the top of my head - I don't plan to implement multi-activity workouts until swimming has been in the app for a while.
