Swift is an innovative new
programming language for iOS and OS X. Coding with swift is really interactive
and fun. The syntax is short yet expressive. The apps built with swift runs
lightning fast. To add, the best part is that Swift code works side by side
with Objective-C. As a language developed wholly by Apple, it’s the bright
future for iPhone and iPad app development.
Swift was developed with a lot of
research on programming languages. The decades of experience building Apple
platform is an extra topping. The creators of Swift have had the advantage of
viewing many languages grow and mature .The named parameters brought forward
from Objective-C are expressed in such a way that the APIs in Swift is really
easier to read and maintain. And the best part is No More Semicolons!
Inferred types make code cleaner
and less prone to mistakes, while modules eliminate headers and provide
namespaces. Any time you declare a variable implicitly, Swift automatically
infers its type at compile time. It does this by scanning your code and
determining the best type based on how you use the variable. Memory is managed
automatically, and you don’t even need to type semi-colons.
Closures are unified with
function pointers. Closures are stand-alone blocks of functionality that can be
used throughout your code. Dependent on the context in which they’re used,
closures contain references to variables and constants.
Generics allow you to create one
function for multiple inputs. This means you can cut down on duplicate code,
making your program more concise and efficient.
Tuples allow you to store
compound values in a single variable.
Fast and concise iteration over a
range or collection
Functional programming patterns,
e.g.: map and filter
Swift was designed to have a low
barrier to entry. The core syntax is simple and clean, and can be run in an
environment called a Playground, an interactive programming environment that
immediately displays the results of your code. Playgrounds make writing Swift
code incredibly simple and fun. Type a line of code and the result appears
immediately. If your code runs over time, for instance through a loop, you can
watch its progress in the timeline assistant. Not only is this useful for
developers experimenting with new frameworks or libraries, it’s also incredibly
useful for those learning how to program.
Swift is rapidly becoming one of
the most-loved and most-used languages by developers. As the future of iOS
development, usage will only continue to increase. Apple has made it clear that
Swift is the future of iOS and OS X programming. As a result, an increasing
number of developers and companies are picking up the language and porting
their apps.
Swift eliminates entire classes
of unsafe code. Variables are always initialized before use, arrays and
integers are checked for overflow, and memory is managed automatically. Syntax
is tuned to make it easy to define your intent — for example, simple
three-character keywords define a variable (var) or constant (let).
In the 2015 Stack Overflow
Developer Survey, developers listed Swift as their most loved language to
program in.
So, you can say that this is one
of the promising languages of 2015 to be engaged in!
