Make certain that you have an Apple ID that you will use for your development, and then choose your program. If you are working for a business or are enrolled in a school, check to see if you are eligible to join a program there: It may save you some money. Planning Your Environment Your development environment is centered around a Mac with Xcode installed on it, but you can use several Macs for development. Each one should have Xcode on it (see further topics in this section for a discussion of multiple versions of Xcode).

This opens the Font window.  Chapter 1: Setting Up an Xcode Swift Project Figure 1-7: Setting fonts and colors. Use + at the bottom left to add a new style. You can provide a title for the new style, as well as set colors and fonts. To experiment with these settings, begin by creating a new style (as shown in step 6) before you modify the existing styles. Use the Text Editing tab to set editing and indentation preferences. The editing preferences are shown in Figure 1-8.

You can use the + and – buttons below the lists to adjust them. Explore your Swift files. You can look over these at this point, but don’t touch. Look at the text fonts and coloring. If you don’t like the way your code looks, adjust those preferences until the code looks meaningfully colored and indented. You may also want to resize your window to make lines wrap better. Remember that you can show and hide the navigator and utilities areas at the left and right of the window. Experiment! Build and run the project.
