Stretch Problem

Longest Word in String

1. Write a function that takes a string and returns the biggest word in that string.
2. Make sure to remove punctuation and whitespace.
Example output:
longestWord("This string, has a gigantic! word in it...") returns "gigantic"
longestWord("one, two, three") returns "three"
Hint: Look up NSCharacterSet methods to remove whitespace and punctuation. Create the charSets as NSMutableCharset objects so you can combine the two CharSets. Call the componentsSeperatedByCharacterInSet method on the parameter string to get an array of strings after separating them by the charSets. Loop through the array to check against your return string length.

Solution

Guided Project

Bulletin Board

Simple project teaching CloudKit concepts and APIs including fetching, saving, and subscriptions.

Project

• Timeline

  Timeline is a simple photo sharing service. Students will bring in many concepts that they have learned, and add complex data modeling, Image Picker, Collection Views, NSURLSession, Firebase, and protocol-oriented programming,

  This is a Capstone Level project spanning many class days and concepts. Most concepts will be covered during class, others are introduced during the project. Not every instruction will outline each line of code to write, but lead the student to the solution.
