Notes

Since this is my first iOS and Swift app, my focus is simply to try some of the features proviede by iOS and Swift. As a result, I haven't spent time improving the UI, but I do have tried to make the app as intuitive as possible.

Also, though the app looks generally good on old iPhone screen size, the app layout does not fit the bigger screens in iPhone 6, which is the issue I have not resolved.
