Not much take up.
The problem in this case is that IBM and a few others were looking for an alternative to Java for server-side use that wasn't tied in with a potential competitor, and as Apple had just come out with Swift, they thought this would solve that problem.
However, Apple remained the driving force behind Swift and they had no real experience with or interest in third party server applications. IBM and friends on the other hand did, but were not able to build a viable community around Swift. Without that community the third party activity to build a large ecosystem of third party libraries and software tools never really developed.
There's lots of fairly good programming languages out there. The few who make it past niche applications and hobbyists into the mainstream are the ones which build up a large and active community.
For example, look at Python. It succeed on a shoe string and without corporate backing because of the community built up around it.
I'm not surprised to hear this news about Swift, as the writing on the wall was evident years ago.
