Three buttons control the visibility of the navigator area, debug area, and utility area.

Choose from this menu the macOS or iOS device (or simulator) the build and run operation will execute on. A look at these options is provided in Debugging Options in the Scheme Editor. For most uses, the defaults created with a project suffice, but there are useful debugging options configurable in the scheme editor’s Run action. Xcode schemes control the build process based on the settings they contain for the Product action you choose and the target build settings. Click to stop the current running task or app. Note: The Run button presents an alternative way of choosing actions from the Product menu. Using the Shift key modifies the menu to a “Build for” operation similarly, using the Control key modifies the menu to perform an action “without Building.” The default operation is to build and run, which starts the debugger as well. Click and hold to select other actions (Run, Test, Profile, Analyze) from a menu. The Xcode toolbar contains the most basic controls you need to start debugging. For a basic introduction to LLDB, see LLDB Quick Start Guide. The Xcode debugger provides all the functionality needed for most debugging situations, but a little familiarity with LLDB can be helpful. LLDB is tightly integrated with the compiler, which enables it to provide the Xcode debugger with deep capabilities in a user-friendly environment. The Xcode debugger uses services and functions provided by LLDB, the underlying command-line debugger that is part of the LLVM compiler development suite. In other words, how you put a tool to work for you often determines which part of the debugging effort it addresses, and it is the combination of what the tool does, what data using it uncovers, and your creative insight into the context of the situation that delivers success to your debugging efforts. For instance, you use the Quick Look feature to inspect the state of a graphical object as you work through a problem, but you can also think of it as being a discovery tool, using it to see how a complex graphic is “assembled” as you iterate through a set of drawing calls. Think of the debugging tools as addressing the five parts of debugging more as a function of how you use them.

The division of labor in these five parts of debugging are not necessarily reflected in the specifics of the debugging tools, although some tools are more pointed at discovery (for instance, the debug gauges), some are particularly useful for dealing with locations of interest in your code (breakpoints), and others are more specific to inspection (the debug area’s variables view and the debug navigator’s process view).

After editing, run the app and check it with the debugger to be sure the fix was successful. Apply your insight into the cause of the problem to devise a solution, and edit the code to suit.Ĭonfirm. Examine the control flow and data structures of the running code to find the cause of the problem.įix. Determine where in the code the problem occurs. There are five parts to the debugging workflow: The Five Parts of Debugging and the Debugging Tools Here are a few notes about debugging in general and some basic information about Xcode as you begin to read this chapter. The illustration below shows the default layout of the Xcode debugger with the app paused at a breakpoint. To customize how Xcode displays portions of the UI, choose Xcode Preferences > Behaviors.

The debugging UI is dynamic it reconfigures as you build and run your app. The Xcode debugging tools are integrated throughout the Xcode main window but are primarily located in the Debug area, the debug navigator, the breakpoint navigator, and the source editor.
