An anonymous reader writes: In October, Microsoft will publish Halo 5: Guardians, the first game in the series to be developed exclusively for the Xbox One. Microsoft is taking the opportunity to make a big play to become part of the e-sports market. They've announced a Halo competition with $1 million in prizes. As e-sports become more mainstream, and as game streaming has turned into a billion-dollar business, more and more development studios are seeing it as part of their marketing strategy. "When Halo fell out of favor among e-sports players, other games began to take off, often ones that were created with high-level competition in mind and that came from developers that invested heavily in events for professionals. Riot Games has turned League of Legends, its multiplayer online battle arena, into the most watched e-sport in the world, with 40,000 attendees at its finals in Korea last year." Microsoft wants back into that segment, and they're willing to spend big to do so.

New submitter IT.luddite sends word that Hasbro and Warner Bros. have announced Dungeons & Dragons will be getting its own film franchise. They already have a script, and they'll be working with production company Sweetpea Entertainment, but they haven't picked a director, yet. They'll have at least some of the people on board who worked on the D&D movie from 2000, which was a flop. The deal between Hasbro and Warner Bros. comes after a prolonged legal battle about who owned the rights to a D&D movie. They note, "All rights for future Dungeons & Dragons productions have been unified and returned to Wizards of the Coast, a wholly-owned subsidiary of Hasbro."

Let’s say I’m writing an image editor. (I use this example on my blog for historical reasons — because, historically, I like to rib Gus. It should not be taken as indicative.)

Here’s the problem I’m running into:

I have various layer classes (BitmapLayer, ShapeLayer, GroupLayer, etc.) that live outside the responder chain. There’s a Canvas object that is in the responder chain.

So I hook up my menu items and buttons with a nil target and whichever action makes sense.

Now, the Canvas object doesn’t implement the various actions that the layers implement. Instead, the Canvas object implements respondsToSelector: — it returns YES if the selected layer responds to that selector.

And then, if YES, forwardInvocation: in the Canvas object forwards the message to the selected layer.

Well, that’s the design, anyway. Sensible. Time-saving. Simple.

But forwardInvocation and NSInvocation are not available to Swift.

* * *

But, soft! What light through yonder window breaks!

While forwardInvocation: isn’t available, forwardingTargetForSelector: is available.

Which means the Canvas could see if the selected layer responds to that selector, and then does a performSelector: on that layer.

Correct?

If so, then it means that anyone writing an image editor is good-to-go with Swift.

(That last sentence is the rib-Gus part again.)

However, Swift support for forwardInvocation: and NSInvocation would be useful. These things have their uses, and while forwardingTargetForSelector: can take care of some of them, they don’t take care of all of them.
