In love with Swift!

Some days ago I began to work with Swift, the new programming language of Apple, and iOS! Some people even said that I betrayed the movement! LOL! Really, I feel a little sad to let the open source projects in background for a time but for other side I am really motivated to work with new things and learn new technologies.

Swift is a mix of the best of programming languages, she have tuples, dictionaries, nested functions and little new concepts like optionals! I am really enjoying learning a lot with my new tech friends and really liking the new spirit of innovation that surrounds here.

Some basic tips of Swift:

– Variables are generic but you also can put his value type.

– You need ‘let’ or ‘var’ to declare one variable.
let something: String = “This is a immutable string”
var somethingOther = “This is a muttable string”

– Enums can be almost anything not just only numbers.

– Cases in switch can do amazing things like compare if value is some value type or another.

– Default parameters in functions are awesome like in Python!

– Doing for-loops are very fun!
for i in 1..<someVariable.count { makeWhatYouNeed() }

– Lazy properties are crazy and useful
private var someNasty: String
var usefulThing:String { get { return someNasty } set { someNasty = usefulThing } }

It’s easy create some fun to a nerdy guy! For the first time in my life, I have to thank to Apple for this!
