Concentration (Stanford University)

With this App you can play the card game "Concentration", also known as "Memory", on your iOS Device. This is a project made in the Stanford's Course "Developing Applications for iOS" (CS193P, Fall 17/18). My version includes possible solutions to the assignments (required tasks + extra credit tasks).

Features

• shuffle cards
• match cards
• scoring system (+2 for found matches, -1 if selected card was flipped before and mismatched, bonus/deduction dependant on how much time it took to match/mismatch two cards)
• bonus/deduction system dependant on time (+2 if it took <0.75s to find a match, +1 if it took <1.00s to find a match, -2 if it took >2.25s to find a mismatch (at least one of the flipped cards where flipped before))
• label showing time bonus/deduction fades away
• restart button
• random theme (card color, strings (emojis) on card, background, labels and restart button are affected by themes, currently there are 4 themes)
• auto layout using container views

Future Updates

• cleaner code
• choose theme
• choose difficulty level
• better animations

Build With

• XCode 9
• Swift 4
• MVC Architecture

What I've Learned in This Project

How to:

• use access control (private, private(set), fileprivate, asserts)
• use extensions properly
• use computed properties
• use static properties and static/mutating methods
• use filter method
• animate show and fade away text
• get time intervals (Date(), DateFormatter())
