> I actually mentioned that. Like, immediately after the quoted phrase.

I'm rereading your previous comment multiple times but unfortunately still failing to see what you're referring to. The only explanation I can see is "we were quite familiar with Lattner and LLVM, so we were quite aware of his propensity for WIN. That gave me some confidence, going forward."

I'm not quite sure what you mean by "a full system API", and does Apple ever announce a product roadmap? I would definitely be interested in this roadmap of which you speak. :-)

You are correct. It was the next comment I made (so I removed that smartass line).

I apologize.

They have had a Swift roadmap forever. I think it's now kept on swift.org. I'll see if I can find it. I think it's a fairly sparse one. I really only cared about the evolution through ABI Stable. All I needed to hear, was that was a goal.

You are right. They tend to eschew roadmaps, but they did a "hard-sell" with Swift. They knew it would be difficult to build momentum with.

"Full System API" is the native frameworks; UIKit, AppKit, WatchKit, etc., as well as things like WebKit and MapKit.

When Swift was announced, they had APIs for most of that stuff. I was pleasantly surprised. I had a full app, working within a day or so (using beta Xcode, of course).

Ok, but that came later and wasn't present in 2014.

I agree with that. :-)

Swift did of course have bridging to Objective-C and the preexisting Objective-C API. I find it strange to equate language bridging with announcing a full system API — an API originally announced around the turn of the century (can't believe I'm using that phrase now). Cocoa-Java, which no longer exists, also had such bridging, as does PyObjC and MacRuby/RubyCocoa. Still, most of the system API to this day are written by Apple in Objective-C.

That's a good point. I never thought of that. It was actually an old bridge. I remember when they tried to make Java a "full citizen" language. Boy, that flopped...

SwiftUI shows promise, but it is still quite nascent.

Pretty much every bit of code I write is "pure" Swift linkage. I like things like Swift's enums too much to give them up. They make APIs really fun.
