Build a TableView based app that parses a block of text and displays a concordance of Mary Wollstonecraft (Godwin) Shelley's Frankenstein in a table. Each row of the table should display a unique word in it and its frequency count next to it.
-
The usual forking and cloning. This time there is a project inside named Frankentable. Open it.
-
The project has a Table View controller and a Data.txt file with a small excerpt from the book. This file is opened and spat out in viewDidLoad to get you going.
-
Split the block of text into unique words and count their frequency. Probably going to want to use a Dictionary.
-
Display one row per word, showing the word and its frequency, Example cell:
*********************************** * * * Albatross (12) * * * *********************************** -
Sort alphabetically, with a section for each letter of the alphabet, grouping by the initial letter of each word.
-
Sort by frequency, ordered reverse. I.e. the most frequent word should be in the first cell, the least in the last. Section by distinct freqency counts. For example, say the highest frequency was 43 and there was 1 word with that frequency, then a section named "43" would have that one row. If the next most frequent word occurred 22 times, and there were three such words, they would be in the "22" section. And so on.

Optional: If you feel ambitious you could grab the full data via an web request to http://www.gutenberg.org/cache/epub/84/pg84.txt. It would be wrong to call this an API call because it's just a text file. Don't try to turn it into JSON. Just read it like we're doing with the local file. It should still be done asynchronously.
