If you're dissatisfied with objc_msgSend performance, you can write C or C++ seamlessly - or use that other language that's partially designed to address the dynamic dispatch nightmare. If you're dissatisfied with JavaScript

Then you're not writing JavaScript, which was OP's concern. TypeScript is fine (although Elm, Swift, and Haskell are more interesting, IMO).

I've tried JavaScript, and I decided I preferred type safety. This kind of thing: > It lets you do stuff like redefine entire objects, properties or methods at runtime Sounds horrifying to me, because, as in Ruby[1], library authors

Well, these types of problems don't exist in languages that correctly distinguish floating-point numbers and integers as two separate incompatible things. I think that this isn't really a problem with integer division (which is f

How, specifically, are you "coerced" into those services? Voice and YouTube are owned by Google. I'd expect a Google account to just work on all Google properties, without me having to sign up for each individually. If you do

Those are (or were, at least) bridged from NSString. There's a bunch of path handling stuff available as well, because Swift String can be converted to and from NSString.

Swift solves this with "guard" statements, which must return if their condition fails. This is most commonly used in combination with converting optional values to non-optional values, to prevent pyramids of doom. guard le

The problem I have with Netflix recommendations is that while they understand genres, they're not good at recommending good shows. Since I've watched Archer and Arrested Development, Netflix thinks I'd like every mediocre c

I installed the dimmer myself after moving into this apartment somewhat recently, so it's a pretty recent model, whatever that means for a light switch.

Yeah, CFL bulbs are icky blue flickering garbage, and the LED bulbs I've used (Hue), while otherwise fine, don't support my dimmer correctly. Using the Hue app isn't as easy as walking over to the light switch, and they won&#

Why is this downvoted so heavily? Seriously, how is this implemented? I don't think Emscripten works with Swift yet, and even if it did, there hasn't been enough time since the open source release to implement an entire app.

Your cell phone's data is protected by a fingerprint reader or arbitrary-length passcode, while your wallet's data is protected by the other person not having a knife.

What is the purpose of the signature, anyways? Mine never looks anywhere close to the same as before, and most of the readers at the bad grocery store next to my apartment just select seemingly random pixels anyways when you touch it. Is th

Apple Pay is just a nice frontend for Visa, AmEx, etc., with better security - disposable credit card numbers to defeat merchant tracking and leaks.

This is not an issue on iOS. Does Android actually automatically increase permissions without opt-in from the user?

Programming in Swift with protocols[1], generics, and value types is so much more productive than Objective-C for me. The amount of reusable code that you can write now is very high - even throwing away what type safety Obj-C can offer

You also have that problem in a language with non-synthesized setters, because there's no guarantee that they don't do anything - and people avoid permitting direct field access, so you'll be going through a setter with unkno

Many modern-ish languages with OO features (Swift, C#) let you declare that a thing has a getter without having to actually write boilerplate, i.e.: private(set) var foo: Int Int foo { get } etc.

Swift has a passable type system, support for generics, and doesn't use a VM. Tooling support isn't there for Linux currently, so the act of writing code isn't much better than Python (no Xcode-type autocompletion), but onc

It's less beginner-proof, and more "doing bad things proof". The purpose of releasing Swift as open source is that they don't want it to be an Apple language. I can't wait for it to replace Python for scripting -

Swift 3 will be ABI stable, so things will break less - that might not include standard library stability, but Swift projects currently include a copy of the standard library to avoid that.
