I switched back to my beloved Objective-C for the app I was developing. Won't be using Swift for low-level image processing.
Also I have been programming the Mac for a long time and I have a lot of mental investment in Objective-C.
OTOH, I do like the functional, strongly-type features of Swift, but like any higher level language I feel more removed from the machine. That's the price for abstraction.
Can you write the app in Swift (if there are advantages to doing so) and then write the image processing routines/library in C?
I think it’s because that’s the style of Apple’s own (excellent) Swift Programming Language book.
I think it does look nicer than the traditional characters used in these kinds of things.
https://developer.apple.com/library/content/documentation/Sw... says the two are bridged, but doesn’t mention whether that is toll-free.
If that is toll-free, users of Array, just as users of NSArray, should be aware that indexing in them can be O(log n). See http://ridiculousfish.com/blog/posts/array.html
Honestly I never run into performance problems since the volume of data I work with is either really huge and done in a C or C++-based library or so small I would never think about array performance.
Good developers have battery empathy.
