The other impact of sharing so many APIs with Objective-C is that some of the benefits of Swift get lost – especially around strict type checking and null reference safety. Thus, people with experience developing in Objective-C quite obviously have a huge head start with Swift. For the most part you’re actually dealing with the OS X (or iOS) APIs which are shared with Objective-C. Swift does have its own core API which is unique to it, but that’s very limited. APIsĬalling Swift a new language is correct but it would almost be more accurate to call it a new syntax instead. I figure it’s much like have a if events != nil check. The main reason for this is that I can never think of a better name. I’ve dropped into a habit here which might be a bit overly clever – naming the unwrapped variable the same as the wrapped one. That would be painful if it weren’t for the ‘if let’ construct: let events: String? = "" You can’t call any methods from String on a String? variable directly you have to unwrap it first – confirming it isn’t null. A variable of type String is guaranteed to not be null, a variable of type String? might be. My favourite feature is the built-in optional support. Unlike many languages it doesn’t seem to go too far with that though – it doesn’t seem likely that people will abuse its features and create overly complex or overly succinct code. Swift has some really nice language features that make dealing with common scenarios simple and clear. It’s been a great little project to get used to Swift the language without spending too much time trying to learn all the OS X APIs.

The code is up on GitHub if you’re interested – code reviews and patches most welcome. So I’ve been building a very small little utility in swift so I can pull out information from OS X’s system calendar from the command line and push it around to various places that I happen to want it and can’t otherwise get it. In other words, I’m not a complete moron, I’m just a complete moron with Objective-C.Īnyway, obviously when Swift was announced it was complete justification for my ignoring Objective-C all these years and interesting enough for me to actually get around to learning it.

I do however have a ton of experience in Java and JavaScript plus knowledge and experience in a bunch of other languages to a wide range of extents. This is probably best exemplified by the approach to memory management those utilities took: it won’t run for long, so just let it leak. Essentially they were small enough and short-lived enough that I only needed the barest grasp of Objective-C syntax and no understanding of the core philosophies and idioms that really make a language what it is. I’ve picked up bits and pieces of it and even written a couple of working utilities but those were pretty much entirely copy/paste from various sources. Java is a registered trademark of Oracle and/or its affiliates.Ever since the public beta of OS X I’ve been meaning to get around to learning Objective-C but for one reason or another never found a real reason to.
