Exercise

For this assignment, you will be making your own Boggle Text Twist clone using the magic of UITextFieldDelegate.

Data:

The following struct and class provides the data that you will be working with. Have your model choose one of the TestTwistInfo at random on startup.

struct TestTwistInfo {
    let wordCount: Int
    let letters: String
    let words: [String]
}


class WordData {
    static let allInfo: [TestTwistInfo] = [
        TestTwistInfo(wordCount: 27,
                      letters: "cdenno",
                      words: ["conned", "coden","coned", "donne", "nonce","code","coed","cone","conn","deco","done","neon","node","none","once", "cod","con","den","doc","doe","don","end","eon","nod","ode","one"]),
        TestTwistInfo(wordCount: 18,
                      letters: "ehhssu",
                      words: ["hushes", "shush", "hehs","hues","hush","shes","sues","uses", "ess","heh","hes","hue","huh","she","shh","sue","use"]),
        TestTwistInfo(wordCount: 14,
                      letters: "hisswy",
                      words: ["swishy", "hissy","swish", "hiss","whys","wish","wiss","ywis", "his","shy","sis","why","wis"])
    ]
}

Stage One:

• Set up your UI with a text field (user input), a label (messages to the user) and 4 text views (where the correct words will be displayed)
• When the user types in a guess into the text field and presses return, they get a message if their guess was correct, or had any errors and then it gets added to the appropriate spot in the UI.

Stage Two:

• Create another label that represents the letter bank of available letters
• Only allow the user to type letters that are inside the letter bank

Stage Three:

• When the user types a letter, remove the appropriate letter from the letter bank label.

Stage Four:

• When the user deletes a letter, add the appropriate letter back to the letter bank label.

Stage Five:

• Present a message to the user if they guess a word that have already guessed before

Bonus One:

• Add handling for the user guesses all 3-letter words, 4-letter words, 5-letter words or 6-letter words, by changing the background color of the appropriate text view

Bonus Two:

• When the user guesses a six-letter word, display a message, then have the model change to another word

Bonus Three:

• Implement a scoreboard. 3-letter words are worth 3, 4-letter words are worth 4 and so on. The scoreboard should persist as the user goes onto the next word

Bonus Four:

• Improve the UI so that it looks polished
• Add more sample words here

Full Requirements:

1. Letter Bank: You'll need a letter bank for the user to select from. The letters should disappear or be greyed out when the user types it.
2. Letter Checks: You must allow the user to type out only valid letters. Perform checks in your logic to prevent incorrect letters from showing up in your TextField.
3. String Storage: Store valid words in word bank(s) once the user returns.
4. Keyboard UI: Keyboard should resign when the user hits the Return key.
