Come across a task in an Interview or a website that challenges you to this. The thing that intrigues me is a good challenge (and many a times I do struggle with it, I am no Genius) However it is still worth a try.

Chaining cout in swift like C++

In an earlier article, we discussed the possibility of adding a cout like functionality in Swift as seen in C++ (http://swift.oz-apps.com/2015/04/using-a-cout/). There were a couple of impediments that prevented the full functionality of our cout function. Let us revisit that and add chaining

WIP: Use Swift Arrays like Lua Tables

This is work in progress and there are somethings that Swift cannot do where as Lua excels with them. Since everything in a Lua table is a reference or a pointer, you can recursively add table to refer to subtables. You could also store functions in the tables and invoke them based on the key. […]

Tip: Creating an Int from a String in Swift

Talking to a couple of developers over various mediums about Swift has had mixed results. However one thing that came up again and again was that it is a little confusing. While confusing in the literal sense would not be the correct word. So let me elaborate the issue first.

Using a cout << like function with Swift to work with console and String

If you have worked with C++, you might be well aware of the cout function, it is one of the most commonly used functions with C++. That is simply because you can just use it so

and it prints Hello World to the console. Well, using the println("Hello World") is not difficult either, but…
