Swift. A modern programming language that is safe, fast, and interactive

Swift is a powerful and intuitive new programming language created by Apple for building iOS and Mac apps. It’s designed to give advanced developers the freedom and capabilities they need to create a new generation of cutting-edge apps. It also opens up a whole new world of possibilities for everyone else. Swift is easy to learn and use — even if you’ve never coded before. So now anyone with an idea can create something incredible.

Swift has been refined from the ground up. It generates faster code across the board, both for release and debug builds. The Swift compiler is also faster, even while adding new Fix-it suggestions such as where you can use let instead of var. Comments can include Markdown syntax to add rich text and embedded images that display in Xcode’s Quick Help. A new assistant shows your Swift API in a “header-like” view. And new syntax features combined with improvements to the Cocoa frameworks and Objective-C will make your code more expressive, and even safer.


Closures unified with function pointers
Tuples and multiple return values
Fast and concise iteration over a range or collection
Structs that support methods, extensions, and protocols
Functional programming patterns, e.g., map and filter

Native error handling using try / catch / throw

Software Development Methodologies

A software development methodology or system development methodology in software engineering is a framework that is used to structure, plan, and control the process of developing an information system.

There are the following methodologies:

Agile Software Development
Crystal Methods
Dynamic Systems Development Model (DSDM)
Extreme Programming (XP)
Feature Driven Development (FDD)
Joint Application Development (JAD)
Lean Development (LD)
Rapid Application Development (RAD)
Rational Unified Process (RUP)
Systems Development Life Cycle (SDLC)
Waterfall (a.k.a. Traditional)

Black Box Testing

A software testing technique whereby the internal workings of the item being tested are not known by the tester. For example, in a black box test on a software design the tester only knows the inputs and what the expected outcomes should be and not how the program arrives at those outputs. The tester does not ever examine the programming code and does not need any further knowledge of the program other than its specifications.
The advantages of this type of testing include:
The test is unbiased because the designer and the tester are independent of each other.
The tester does not need knowledge of any specific programming languages.
The test is done from the point of view of the user, not the designer.
Test cases can be designed as soon as the specifications are complete.
The disadvantages of this type of testing include:
The test can be redundant if the software designer has already run a test case.
The test cases are difficult to design.
Testing every possible input stream is unrealistic because it would take a inordinate amount of time; therefore, many program paths will go untested.

Follow these steps to clean and secure your website:

1) Lock down your site by using an .htaccess password so your customers are not attacked by the hackers code.
2) FTP all of the files to your local machine and use a program like WinGrep to identify and remove all malicious and anomalous files containing hacker code. Look for keywords such as 'base64','eval','decode'.
3) Delete the files on your hosting account before uploading the clean files.
4) FTP the clean files back to your hosting account and read and implement the security patches and contributions found in these two threads. Admin Security and Website Security.
5) Change all of your passwords: FTP, CPANEL, STORE ADMIN and DATABASE
6) Make sure File and Directory Permissions are set correctly. Directories no higher than 755, Files no higher than 644 and the TWO configure.php files no higher than 444
7) If your site has been 'black listed' as an attack site by Google, then log into Google Webmaster Tools and submit the site to be re-indexed and verified to be removed from the 'black list'
8) Remove the .htaccess password protection so your customers can resume making purchases from your website.
9) Monitor your website using the newly installed contributions to prevent future hacker attacks.
10) If you feel you can not perform any of the above steps, you should seek professional help to ensure all malware is removed.
