Week2

BullsEye Game App Collection

Week 2 Assignment

Refactor the BullsEye project to make it conform to the Model-View-Controller architecture. The app can be used with any iPhone that supports iOS 13

Assigment Requirements completed

• Refactor the ViewController in BullsEye Game to create a UI-independent model.
• Test UI-independent model on RGBullsEye Game replace Int() type with RGB() type.
• modify slider’s minimum track tint color in BullsEye Game to provide a visual hint to the player

Stretch Above and Beyond Requirements completed:

• “Reverse” the BullsEye game to use a text field.
• Modify slider’s minimum track tint color in RevBullsEye Game to provide a visual hint to the player
• Prevent the user from submitting text that won’t work, either because
  • The text isn’t a number
  • The Number outside the slider’s range
• User can dismiss the keyboard using two methods for the RevBullsEye
  1. Tap screen
  2. Tap done button

Additional Assignment Goals completed

• Groups all game projects and packages under one Xcode workspace so it's easier to work on them together
• Model code for games BullsEye & RevBullsEye moved to Swift Package to avoid duplicating code.
• As an SPM Package model code can be distributed to other developers to make their version of BullsEye
• Use Apples Combine framework so UI can listen for changes in the model.
• Show animation when the user has a high score.

Class vs Struct:

My personal preference is always to start with a struct. why you wonder?

Because Crusty said so.

All joking aside,

The reason I prefer structs is the value semantics especially immutability. But as game model required mutation I changed the model to a class to avoid adding mutation keyword to all my model functions. The next version of the 3 games could be rewritten for MVVM so the model is a struct & the view model is a class.

Shared Game assets :

The shared game assets could also be moved from the individual game project to Swift Package. The feature SE-0271: Package Manager Resources will be available in swift 5.3. So the next version of BullsEye & RevBullsEye can take advantage of that.
