Customizing Your Workflow
Specify behaviors that affect your workflow through the Xcode Behaviors preferences. Choose Xcode > Behaviors to specify what should happen when a variety of events occur while building, running, and debugging your app.
For example, Xcode can display the debug area when your code pauses at a breakpoint, and it can display the issue navigator when a build fails.
In the screenshot below, behaviors are customized for whenever the code pauses. Here are some examples of customized behaviors:
Play an alert sound at every pause.
Create a tab named Debug in the workspace window for displaying the debug navigator.
Show both the variables view and the console view in the Debug tab.
Hide the utilities area in the Debug tab.
As a result, when the code in the project hits a breakpoint, Xcode creates a Debug tab in the workspace window with the specified content.
You can design custom behaviors that are triggered by menu items or their keyboard equivalents. Choose Xcode > Preferences, select the Behaviors preferences pane, and click the Add button (+) at the bottom of the pane. Type the name of the new behavior, and press Return. Select checkboxes to specify what should happen when you invoke this behavior. For example, create a Unit Testing behavior that saves a snapshot of your project and runs your unit tests. After you’ve created a behavior, it appears in the Xcode > Behaviors menu.
To assign a keyboard equivalent to a custom behavior, choose Xcode > Preferences and click Key Bindings. In the Key Bindings preferences pane, select the Customized tab to find the custom behavior you want. In the text field, enter the keys you want to use for the key binding in the text field, and click outside the text field to complete the operation.
