Users don't recognize Swing, but I wouldn't say it didn't succeed. There are an unbelievable number of little utilities, obscure programs, and company-internal tools written in Swing that people use every day and don't really think about. Swing didn't catch on much for big name software, but it still manages to be everywhere, and is much of the reason a lot of intermediate users reflexively install Java on new systems when they get them.
