Hi,

I am currently encoutering issues with the starter projects. I am exactly executing every step stated in the book. But for some reason is gives me the following error:

Playground execution failed:

error: Couldn’t lookup symbols:

It’s already being fixed. Apparently more people have this issue:

Please refer to: Playground execution failed for error: Couldn't lookup symbols · Issue #1660 · ReactiveX/RxSwift · GitHub

Hi @shogunkaramazov

This fixed worked for 2 compilations but now it seems it doesn’t work anymore. Especially the playground files do not work.

Errors like:

Symbols not found etc.

Do you know what to do?

@kevinvugts Please try out the solutions mentioned in this thread and let me know if they work for you:

Thank you!

Hey @kevinvugts!

We’re working on a more stable solution for the RxSwift book playgrounds - I was wondering if you’re still having issues? If so, I’d love to send you a demo playground to test and see if resolves your issues.

If it does solve it for you, we’ll be hopefully able to push a similar solution to all of the book’s playgrounds :slight_smile:

Let me know if you can/want to help test this :slight_smile:

Thanks!
Shai.
