SWIFT PROGRAMMING : Mock Remote Control II|

a) The segmented control allows you to select which of the four favorite channel buttons is to be configured. The favorite channel buttons are numbered 1 4 from left to right. b) The text box allows you to enter a short label to be displayed on the favorite channel button. The label must be between 1-4 letters in length. If the label is too long or to short, an alert should popup with an appropriate message. c) The channel number should be in the range of 1-99. The widget next to the channel number is a Stepper object for selecting an integer value. d) The Save button saves the current configuration, while the Cancel button will ignore the current values, and the configuration of the favorite buttons will remain unchanged. If the new configuration is saved, the favorite channels in the TV remote should reflect the new configuration, i.e., the label and channel number will be adjusted according to the configuration.

Below is a previous assignment that I implemented it already :
