Customizing the Editor
Choosing Syntax-Aware Fonts and Text Colors
Xcode parses code based on the language, and it assigns a syntactic label to each token or string—for example, each comment, keyword, and class name defined in the project. Xcode assigns a color and font to each syntactic type to make it easier for you to read the code. You can select from several font and color themes by choosing Xcode > Preferences and then selecting Fonts & Colors. For example, the Presentation theme increases the font sizes so that the text is easier to read when projected on a screen. You can also create your own custom font and color themes.
Customizing Editing and Indenting Options
You can change source editing and indenting settings to suit your preferences. Choose Xcode > Preferences, and select Text Editing to modify options such as these:
Display line numbers in the source editor gutter.
Automatically insert closing braces as you type.
Suggest code completions while you enter code.
Use spaces or tabs for an indent.
Perform syntax-aware indenting.
