I just prepared a python script that is downloading the tar.xz the podspec files are pointing to. I do not use the podspec itself in my project but in the past copied the URL in the podspec to download the VLCKit builds, whenever there is a new version.
So I did it yesterday based on the branch "3.0" which features the latest beta as "unstable". I assume, that after finishing the beta, this will be merged to master branch.
I was just a bit confused, that the downloaded file is named "VLCKit-3.3.18b1-d83fc519-1f870b73.tar.xz", I first thought it might be an issue in my script

In the repo I found the commit 32babf755496b41a3f55697f31331608a0e95d5f where you updated the podspec files and saw, that you updated the version number to "3.3.18b2", but not the filename. So I thought, just worth to mention, even it is not a real issue

I will anyway now integrate the beta in my project and check for issues
