When you run your code and get an unhandled exception, you can click Create breakpoint in the Run window to add a breakpoint to your code. In the Breakpoints popup, set the desired configuration for your breakpoint and click Done. Debug your code using the shortcut ⌃D (macOS) / Shift+F9 (Windows/Linux). Code execution will stop at the breakpoint, and you can examine the state of your application in the Debug tool window.
