While I was waiting for updates to download I finally took a look at Microsoft’s Objective-C ‘bridge’ for porting iOS apps to the Windows 10 platform.
It’s technically a pretty nice system; they’re using clang to build your Objective-C code natively to the Universal Windows Platform as native x86 or ARM code, with an open-source implementation of (large parts of) Apple’s Foundation and UIKit APIs on top of UWP. Since you’re building native code, you also have full access to the Windows 10 APIs if you want to throw in some ‪#‎ifdefs‬.
I suspect there are a lot fewer ‘moving parts’ in it than were in the ‘Project Astoria’ Android bridge (which would have had to deal with Java etc), so in retrospect it’s not super surprising that they kept this one while canceling the Android bridge.
I don’t know if it’ll get used much other than for games that targeted iOS first and want to port to Xbox One and Windows tablets easily, but it’s a neat idea.
Probably tricky to get something like the Wikipedia app working since that app does lots of WebView magic etc that’s probably a bad API fit… but might be fun to play with!
