Project 17, part 4

Continuing with Flashzilla

Coloring views as we swipe

• Swipe right → correct
• Swipe left → guessed wrong
• take care to consider differentiation without color

Counting down with a Timer

“Add a little bit of pressure to get the user to speed up”

I really don’t like timed games

Detect when the app is moved to the background so the timer doesn’t cheat you out of seconds

Ending the app with allowsHitTesting()

Use to disable swiping cards when the timer runs out
