Use the recently created iOS app as the baseline and extend it to provide the following features:
- Add a text box to allow the user to enter the text that the game names must match in order to be displayed as an option in View Picker
- After the user selects a game in View Picker, display a new view that shows the highest score and the played count for the chosen game
