When we create a project from an Xcode template, the resulting App needs to be customized to provide the interface that we want in our App. So as soon as we have created the basic project we need to make our interface changes.
Note
Because the sample program code used in this and the next section is both short and concise, the explanation of the code is included in the code as comments rather than using descriptive text surrounding the code. We can identify comments in the program code by looking for the // characters that start each line or the /* and */ characters that surround a block of comments in the code. We need to become comfortable with reading program code and distinguishing the comments in the code, from the code.
The way that we implement our features is to open the files created from the template and change their contents to include the new program code that implements the behaviors that we want to add.
