Building error for Kivy-ios. Failing to download openssl
Trying to build my first kivy app for ios. Following this video: https://www.youtube.com/watch?v=6gLGyrlgqCU
When I run toolchain build kivy it gets stuck downloading and openssl link. I don't know anything about ssl. Any help is greatly appreciated.
i also tried toolchain build openssl but that had the same error result

Solution
I found the issue on my own. I needed to install Certificates.command from python's application folder.
