Hi
I have downloaded
I am not able to build demo cause of a few errors as follows

Also should mention that this is using the latest version of the SDK and demo

Hi @petergpls.

We have just released an update to Photon UE demo project, that makes it compatible with UE4.18.

Please re-download the demo zip and try again.

Also please replace the version of ToStringImplementation.h that ships with version 4.1.8.1 of the Client SDK with the version at https://www.dropbox.com/s/7zke9qaviu1tejz/ToStringImplementation.h?dl=1.

This new version of the file includes a fix for those "instantiation of variable 'ExitGames::Common::Helpers::ToStringImplementation::converter' required here, but no definition is available" errors that you can see.

Versions of Xcode prior to 9.1 did not throw this error, so this issue only popped up recently.

We will of course include this fix with the next release.
