| | The Swift computer language is the brainchild of a number of Apple associates. In my humble opinion it shows some nice features, but also some warts. Part 1 (constants, variables, strings, tuples, arrays) explores a number of the features to give you a taste of the language. I hope I … |
| | Part 2 of exploring/tasting the Swift language takes a look at dictionaries; process flow controls like loops, if/else and switch/case; functions and sorting. I hope I can follow this up with part 3, a closer look at class operations.  |
| | In part 4 of tasting Swift, we explore structures. Swift has added some interesting features to structures like defaults, methods, multiple init(). This way struct objects come close to class objects with a little less overhead. As an option, methods can be added externally too. Take a look! Down the … |
| | This is the updated version of the Tiny Tkinter Calculator. It has more power, since you can type in functions contained in the Python math module then press the equals key. You can then move the result into memory for other calculations. The code is written in OOP class style … |
| | Like most modern languages Swift has sets and set operations. Here is a quick look. Coming in the fall of 2015 ... Swift2 replaces println() with just print() that has a newline default. The sort of thing that Python3 did to print(). There are some other syntax changes. Good news, … |
| | The example shows how to establish a dictionary of (row, column):value pairs to mimic a two dimensional array. This can be easily expanded to more dimensions. Python3 has dictionary comprehension, making the process of creating a dictionary of this type easier. |
