In Xcode, when execution stops at a breakpoint, is there some way to skip some lines or go back? In other IDEs like Visual Studio, you can drag to the target line using mouse.
There is. To skip the breakpoint and go to the next one hit F6, to step into the code hit F5.
Here’s a full list of shortcuts for XCode: https://developer.apple.com/library/archive/documentation/IDEs/Conceptual/xcode_help-command_shortcuts/MenuCommands/MenuCommands014.html

I have VSCode Windows and Microsoft Python extension installed.
By pressing F5, the IDE just executes my code immediately. I don't get the chance to choose if I want to run the code or to use debugging features like step-over or step-into. The debugging menu bar appears on top and disappears very quickly.
In some tutorial videos I see that pressing F5 actually brings up that menu bar. Then the developer has to choose to run the program or step it. I want the same thing.
Please assist.
so first you have to add a breakpoint in which the debugger will pause at the line of code. You can add the breakpoint by pressing f9 in the same line of the code. After that, you can press f5 to debug the code and later on press f10 to step over!
I am working on a program and a lot of the buttons and menu items are dynamically created. Its especially hard to work on because I don't know where they are created and assigned to. It would help if I could start up the program via debugger, get to the menu, then switch to "line by line" style debugging like pressing F10, where the next line of code ran would break, and then press one of the buttons to get more info about it once the break happens. Is there any way I can do this in visual studio?
In Visual Studio, you have the Solution Explorer. There you see the Project files, they are under the top level Solution. If you right click on your main project, go to: Debug > Step Into New Instance.
If you work on a .NET application, you can use my Runtime Flow tool to see what code is executed when you select a menu item or press a button.
The closest way I could figure out how to do this is to go into Debug>Disable All Breakpoints and then when I get to where I need to be in the program go back and Enable All Breakpoints. Of course this only works if there is a large number of breakpoints in places in the program.
How can I find out which line will be executed after performing any action?
If I know what will be executed I can put break point there. But what if I am not sure where to set breakpoint or just I need to go to the executing line faster (without setting breakpoints).
"Break All" is not what I look for. It is pausing debugging, so I cannot perform any action (just after which I want Visual Studio sets breakpoint automatically)
In other words, for example I want to start debugging each line after clicking a button, without putting breakpoints. Is it possibile?
For a .NET application you can use my Runtime Flow tool (30-day trial) to see code that is executed after some action.
Set a breakpoint at the line you want to stop after. Then once the breakpoint is hit Step Into or press F11 in Visual Studio. This takes you to the very next line of code that executes, no matter where it is in the project.
I want to remove several breakpoints along my program execution path. XCode stops at each breakpoint and I want to clear it immediately. In contrast to all other tools that I used to, Xcode does not put cursor on the line it stopped. Therefore, "toggle breakpoint" shortcut instead of clearing current breakpoint, puts breakpoint somewhere out of sight.
To clear current breakpoint I need to grab mouse or press extra shortcut before actually clearing breakpoint. It gets very annoying for several breakpoints in row.
Maybe there's workaround?
You can click inside the topmost thread in the Debug Navigator ⌘+6 to see where you stopped.
If you want to automatically skip a breakpoint or perform other actions when it's triggered you can Right-Click or Control+Click the breakpoint, choose Edit Breakpoint... then check Automatically continue after evaluating actions.
How can I prevent Visual Studio from tracing into strlen() and other such functions?
I have a source line like:
i = my_function(x, strlen(x));
When I step into this line of source, I don't want to step into strlen(), but only my_function(). Is there a way to remove these as I encounter them?
You can right-click on the line in the debugger and choose to step directly into my_function, or if the call has multiple argument function calls, you can step into one of your choosing from the right-click menu. This doesn't let you skip those automatically, but it is helpful.
Assuming you mean stepping through the code in the debugger within Visual Studio. You should be able to just press F10 to step over code when you're on that line. If you press F11, that'll step into the code which means you'll travel down into the code for strlen().
