Changing the gears to Generic Programming
Practical usage of generic programming can be narrowed down to two forms:
Subclassing UILabel in 2015
UILabel is one the most smart view in UIKit family. It knows a lot
about itself. If you constraint it to a certain width, the UILabel can
calculate the height for itself. Another smart thing about UILabel is
that is saves you machine cycles by not redrawing its content unless
something is actually modified. And if you use NSAttributedString, you
can in fact draw a more sophisticated text content.
Curious case of Generics Specialization with Swift
Today, I want to talk about a curious case I discovered while playing with generic programming with Swift.
Concurrency: Atomics
I think we have covered most of the core concurrency concepts. With the
current knowledge we are good enough to tackle all real world
concurrency related problems. But this doesn’t means that we’ve covered
everything the thread libraries have to offer. And by thread libraries I
mean just the C++ standard thread library and libdispatch. For example,
we’re yet to see std::future, std::promise, std::packaged_task,
dispatch_barier, dispatch_source in action.
