At the timeframe discussed on the panel, I don't think Swift is really lagging. In few years, it has gone rather well, and in few more years, it should mature a lot more on multiple platforms. Right now, I think attempting to use Swift on a Linux server would be a big nuisance; it's enough to look at the open-source implementation of Foundation & co. and the many trivial things still missing. Once that is complete, it should start becoming more interesting. I don't think the push for Windows support will be very difficult.

I beg to differ. Look at Vapor, Kitura & Perfect.
I know Foundation is missing implementations for Linux, but it is not something that makes it a big nuisance IMO.
You can quickly have a setup with Swift on Linux running a simle CRUD app.
Yes it is possible and IBM is the one pushing for it.
However it is still light years behind JEE and Spring features, including parity with existing JDBC drivers.
Also besides instruments on OS X, there are no comparable performance monitoring tools like VisualVM, Mission Control and many others from the JDK vendors.
But as far as I know, Instruments is using tools available already in lldb, clang and dtrace. So building a UI that displays the collected data should be more than possible.
