They are very similar to strings in Javascript. StringsД«efore we get to arrays and dictionaries, there should be a short note on Strings in swift. These variables can also store objects created from class or struct (we will get to them later). This includes any Integers, Strings, Booleans, or nil (SwiftвЂ™s alternative to JavascriptвЂ™s undefined and null). All you have to do is assign a variable the type of Any: var x: Any = 2ДЄnd just like that, x can now store any value. If we want that power, itвЂ™s really not that hard. This way, it can help you avoid a whole set of problems. In fact, if thereвЂ™s even a chance that may not happen, the Xcode will complain at compile time. Swift will make sure that a variable with the type Int always has an Integer value. But this limitation, can also help you in many ways. Obviously this is a more limited compared to JavascriptвЂ™s variables where you can pretty much store ANY value in a variable. This time the compiler makes no assumptions since you told it that you want x to store Floating point numbers. And so if you wanted to store floats in a variable and initialize it with a value of 2, you could also do this: var x: Float = 2 The вЂtype inferenceвЂ™ is a convenience feature in Swift, but you can also define the type yourself. But in the second example, but putting the decimal point, youвЂ™ve made your intent clear that you want to store floating point numbers.

Though the two code block look similar, in the first example the compiler will assume you want to store integers, since 2 is an integer. Notice that this would be an error too: var x = 2 When we assigned x=2, the compiler assumed we want to store integers in x. If you have any experience with a language like C, you know Int means an integer. The above code becomes this before it runs: var x: Int = 2 The compiler is actually adding code for you. This is valid Javascript code but in Swift, it will throw an error. But what really happens behind the scenes is a little more nuanced. The semicolon is optional in both languages too. Really the way you define a variable is identical in both languages. Variables, Arrays, Functions, and Hashes (Objects in Javascript, Dictionaries in Swift).

Given the depth of both languages this will probably become a series of blog posts. And even in places where the languages are very different, there are ways where Swift can be written in a way that makes it more like Javascript. Going over the language, I see the many similarities. Others have also compared Swift to Go, Scala, F#, C# etc. It is then but natural for lots of people to directly compare Swift with Objective-C.

It uses the same APIs and in fact you can use both languages in the same project. One of these is the fact that Swift is completely compatible with Objective-C.

The syntax may be similar but there unique characteristics to the language that are not out there in any other language. Apple has managed to create a whole new language that borrows heavily from many other languages but eventually is something unlike anything out there. But the biggest surprise was the new language called Swift. This yearвЂ™s WWDC was a big surprise for anyone following Apple. This article was originally posted on his blog.
