[swift-evolution] Swift Performance (JSON parsing, for example)

[Vanderlei Martinelli]

Hello.

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:
https://blog.sudeium.com/2014/12/10/swift-performance-too-slow-for-production/

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?

Regards,

-Van
