Hello,

Thanks for the submission! Things look good - I like that you added some color to the application. As one small note, in the U.S. we often use two decimal places (so you should use %.2f but that is no big deal.

"Saving" the default tip percentage across restarts was an optional task, which is pretty easy: if you ever have time, look into NSUserDefaults.

Other than that, the submission looks good! I'll send you course details shortly.

Hi Charles,

Thank for your tips!

I've finished an option task: "Remembering the bill amount across app restarts" using NSUserDefault.

However, could you let me know how to handle the condition (if < 10mins) in Swift?

Thanks, Bao

Nothing fancy - just using NSUserDefaults to store a timestamp. When the application is closed, just record the time, and when the application becomes active, check to see how long it has been.
