This is not a request for change in the syntax and I don't if this is the
appropriate place, but for many Swift programmers experience and my own
experience, some things in Swift are very, very slow than Objective-C and
other languages. One of these things is parsing JSON data using
dictionaries/arrays (using Swift native types or NSDictionary, the result
is near the same).
You can read more info in articles like this one:
Other thing: since I am talking indirectly of JSON parsing, there is some
expectation that it be handled natively on the Swift, with a suitable JSON
data format than just dictionary/array?
That particular article is almost a year old. We looked at this very workload and improved its performance significantly in Swift 1.2.

If you find a specific test case that is slower than objective-c, please create a benchmark and contribute it via pull request. The benchmarks are located in ./swift/benchmark/
