Activating Swift extension failed on ARM Windows 11

[joakimsuarez]

Hi,
I', on windows 11 and ARM (Surface Pro) and I get this every time I start VS Code. As a result e.g. outline is not working.

"Activating Swift extension failed: (t || "").replace is not a function"

what can I do to fix it?

Kind regards,
Joakim

Did you manually override the swift.path setting? If so, what is it set to?

Hi! I had a look in vs code settings and had this in my workspace settings: // "swift.path.swift_driver_bin": "C:\\Users\\joaki\\AppData\\Local\\Programs\\Swift\\Toolchains\\6.1.3+Asserts\\usr\\bin\\swift.exe", // "swift.path": "", commented them and restarted, got: appleMyCore: The Swift extension would like to update launch configurations 'Debug appleMyCoreCLI (appleMyCore) and Release appleMyCoreCLI (appleMyCore)'. Do you want to update? Clicked update and now everything works fine! Outline as well. You can then close this. Many thanks! :) Joakim

Thank you for confirming! The extension should provide a better error message here. So, I'm going to leave this open to fix it.

True, sounds good. Thx again 👌🏻
