[swift-users] So how do you implement a NSTextStorage subclass in Swift?

The `string` property of `NSTextStorage` is of type `String`, but the contract it must implement is that it should return the backing store of the attributed string (the underlying `NSMutableString` used as the backing store). It seems to me that this makes it impossible to implement correctly a

The decision to move from the mailing list may have surprised many but the discussion on it has been ongoing very strong.

Easy explained - The problem rises indeed not from the added features but from the fp group that imposes it’s usage in the Standard libraries and “the swifty way”. I like many features of Swift (or I wouldn’t be here) but I don’t want to live in Haskel world. And for some reason these guys becom

Re: [swift-users] [swift-evolution] Plan to move swift-evolution and swift-users mailing lists to Discourse

I have a simple question along this line: How does expanding the capabilities of Swift detract or impair its use in a fully OO manner? From what I have seen, if you want to use it in a strictly OO manner, great! If you want to use it in a strictly functional manner, no problem. If you want to us

My problem with Discourse lies in its terrible ui. It is like most modern social media: totally useless to find stuff and stay organized in it. It reminds my heavy on the terrible ui of Facebook and the redone developer forums at Apple that have gone from fine to utterly useless chaos. Perhaps

Re: [swift-users] Problem with console apps

A follow-up: flushing stdout works in console, but not in Xcode. Neither setbuf(stdout, nil) nor fflush(stdout) helps, so it appears this is an Xcode issue. import Darwin setbuf(stdout, nil) while true { print("A question.") print("Your answer: ", terminator: "") // not printed //ff

Great news — and I guess it's a plus that Discourse isn't PHP but Ruby, as I expect there are quite a lot Rubyists around here. So, hopefully the issues that might exist (especially with the mail interface) can be addressed to make everyone happy. Although Discourse looks like a really good fit,
