Create a take in data function to read original price, amount bought, and selling price from text fields, convert strings to numbers, and prepare for price calculation.

Learn to calculate profit by combining selling price, amount bought, and original price, test with examples, and format output with a dollar sign while debugging code.

Learn to build a savings app for iOS 9 that tracks weekly and yearly savings, using Xcode in the Tauriel series, with a focus on creating an effective, user-friendly app.

Design the app interface by adding and arranging labels and a numeric text field for income, including hourly, weekly, monthly, and yearly income and savings percentages, with a decimal keypad.

Learn how to print variables by wiring hourly, weekly, monthly, and yearly income and tax values into text, and display monthly and yearly savings and percentages.

Hide the keyboard in an iOS app by adding a hide keyboard function, resigning first responder, and using touches began; test early and often, and fix input issues.

Test the app and set up the clear functionality to reset all labels and text fields, adjust the UI layout, and verify calculations for weekly, monthly, and yearly savings.

identify and fix final bugs in the app, refine the monthly savings calculation to percent, and run tests to show how saving $111 a week yields about $6k yearly.

Explore how the app calculates earnings per hour, per week, and per month, shows savings amounts and saving percentages, and tackles the challenge by adding more financial items.
