Step through the program
Stepping is the process of controlling step-by-step execution of the program.
AppCode provides a set of stepping actions, which are used depending on your strategy (for example, whether you need to go directly to the next line or enter the methods invoked on your way there).
The stepping buttons are located on the Debug window toolbar.
Step over
Steps over the current line of code and takes you to the next line even if the highlighted line has method calls in it. The implementation of the methods is skipped, and you move straight to the next line of the caller method.
Click the Step over button
or press F8.
If there are breakpoints inside the skipped methods, the debugger will stop at them. To skip any breakpoints on the way, use Force step over.
Step into
Steps into the method to show what happens inside it. Use this option when you are not sure the method is returning a correct result.
Click the Step into button
or press F7.
Some methods are skipped by Step into as you normally might not need to debug them. This list can be fine-tuned on the page of the Preferences dialog (⌃ ⌥ S).
Step out
Steps out of the current method and takes you to the caller method.
Click the Step out button
or press ⇧ F8.
Run to cursor
Continues the execution until the position of the caret is reached.
Place the caret at the line where you want the program to pause.
Click the Run to cursor button
or press ⌥ F9.
Also, you can Run to Cursor by clicking the line number in the gutter.
You can configure whether you want Run to Cursor to work on clicking a line number in .
To skip any breakpoints on the way, use Force run to cursor.
Force step into
Steps in the method even if this method is skipped by the regular Step Into.
Click the Force step into button
or press ⌥ ⇧ F7.
In case the source code of the method or function that you want to step into is unavailable, you can debug disassembled code in a dedicated view.
Force run to cursor
Continues the execution until the position of the caret is reached. All breakpoints on the way are ignored.
Place the caret at the line where you want the program to pause.
From the main menu, select or press ⌃ ⌥ F9.
Force step over
Steps over the current line of code and takes you to the next line even if the highlighted line has method calls in it. If there are breakpoints in the called methods, they are ignored.
From the main menu, select or press ⌥ ⇧ F8.
