How to upload on iOS?

Hello, I’m new to this website so I’ve never uploaded or messaged anything. But, in my Youtube channel, I want to send a link for people who want my world. If this is not available on iOS, please let me know. And if yes, then how? I already know how to upload, but the thing is, I can select the folder to upload it. Thank you!

You need to connect your iphone/ipad to a mac/pc using your charger . then open itune on you pc and choose your connected device. head to the minecraft folder / save/ and copy your world to your pc.
change the world (lol) to a zip format and upload it!

Cool! Thank you for your help! I will try that soon.
