Hi @DavoBR,
Can you check if you are using the latest version of nativescript vs code extension - 0.8.1? Also, does this happen when deploying the app on a device or on a simulator?
I tested the VSCode debugging with Launch on iOS option and the project stopped on the breakpoint.

Hi @tsonevn,

I am having the same issue. For me I have the newest code extension installed (0.8.1) and tried it with the latest nativescript version (4.2.4) and the nativescript RC 4.2.4-2018-09-17-12236. I used node version 10.11.0. For me it happens when deploying on a simulator, didn't have the chance to try deploying it to a device in this setup yet.

the first time I had installed node 8.12.0 now I install version 10.11.0 but likewise the error persists.

this is the output of vscode after start debug

Is there a way to solve it? Same happens to me when I tns debug ios from the terminal without VScode

[tsonevn]

Hi @racknoris,
Can you try restarting the device and simulator, that you are using for debugging then start again the tns debug ios command?

[JonLevy]

Edit: It turned out I needed to brew uninstall and reinstall python. Now it is working.

The problems initially:

tns debug ios is working for me, but not the VSCode extension.

When trying to use the extension, the debugger fails to attach. Here is a sample output:
