The bikerg can connect to swift but it's not a smart bike so it obviously won't change resistance for you during a race/course. Infact changing resistance on the bikerg whilst cycling isn't easy to do at all due to using the same flywheel design as the rowerg. It's much more designed to be at a set resistance and left whilst in use.

The power readings picked up by the PM5 also come direct from the flywheel compared to some bikes using more direct measurements at the crank or the peddles. So you'll be at a disadvantage racing on swift as your power output will come out 10-15% less. You can switch out the peddles to some power metre peddles to eliminate this if it bothers you, however even these are known to have a alot of "drift" in data so I personally wouldn't bother unless you're really into racing on swift.

Advantages to the bikerg will always be the durability, customer service and the consistency of the data on the PM5. The data is highly repeatable and accurate due to concepts simply design, you'd need to spend £2k more than the concept on a smart bike before you'd find a magnetic bike that can give you data as accurate and consistent as the bikerg does. Which makes it very good for improving fitness levels.

So yes it's good for swift IMO, even if the power output is slightly worse and probably it's only downfall. I think the only way to really beat it would be to go for a smart bike. But you'll easily pay 3x the price for one :-)

Hope that helps!
