Update Dependencies (request)

[paulrd]

Trying to update dependencies (swagger-service) - using lein-ancient - results in some errors. Looking into it so far reveals cljs problems with spec (clojure 1.8 -> 1.9 breaking change?) when I run lein figwheel. There are various other issues when trying to run on upgraded dependencies. I might look into this as an exercise, but I'm pretty new to luminus and web dev.
