Kubernetes (from open sourcing to about 1.3 or 1.4) is a second system mostly written by senior engineers (from several companies) with deep experience in the problem domain and strong architectural guidance, and a willingness to stop at “just good enough” and then let stuff mature. Kube was mostly “done” from a design perspective in early 2015. Swarm was 2-3 people in the early days, without as much strong opinionation about what exactly they were building, which meant while it was a tighter, simpler system, it couldn’t evolve as easily. I’m obviously biased - I was the first non googler to have commit on the repo. But it’s much easier to build something when you know upfront exactly what it looks like and you have a set of committed and experienced engineers with good leadership.
