Share folders and files in iCloud Drive on iPhone
After you set up iCloud Drive, you can use the Files app 
to share folders (iOS 13.4 or later) and individual files with friends and colleagues. When you share a folder or file with iCloud Drive, you send a link to the item, not a copy. When you make changes to a folder or file, others see your changes automatically. If you allow people to make edits, their changes appear automatically as well.
Folders and files shared in iCloud Drive have these important characteristics:
If you share a folder, all items added to that folder by you or other participants are automatically shared.
The link to a shared file includes its name. If the name or content is confidential, be sure to ask recipients not to forward the link to anyone else.
If you move a shared file to another folder or location, the link no longer works, and people lose access to the item.
Depending on the app, users might need to reopen a file or tap the original link to see the latest changes.
Share a folder or file
If you own a folder (iOS 13.4 or later) or file in iCloud Drive, you can invite others to view or change its contents.
You can share a folder and file so that only people you invite can open it, or anyone with the link can open it.
You can allow the contents of a folder or file to be changed, or you can restrict access so that the contents can only be viewed.
When you share a folder, only the people you invite can access the files in the shared folder. To invite more people to access the files, you must change the settings of the shared folder to add more participants. You canʼt select an individual file within the shared folder and add participants to it.
Touch and hold the folder or file.

Access option: When you change the access option from “Anyone with the link” to “Only people you invite,” the original link no longer works for anyone, and only people who receive a new invitation from you can open the folder or file.
Permission option: When you change the permission option, everyone who has the file open when you change the permission sees an alert. New settings take effect when the alert is dismissed.
Change access and permission settings for one person
If you’re the owner of a shared folder (iOS 13.4 or later) or file and its access is set to “Only people you invite,” you can change the permission for one person without affecting the permission of others. You can also remove the person’s access.
Touch and hold the folder or file.

Stop sharing a folder or file
If you’re the owner of a shared folder (iOS 13.4 or later) or file, you can stop sharing it.

, then tap Show People.Tap Stop Sharing.
Anyone who has a file open when you stop sharing it sees an alert. The item closes when the alert is dismissed, the file is removed from the person’s iCloud Drive, and the link no longer works. If you later share the item again and set the access to “Anyone with the link,” the original link works. If the access is set to “Only people you invite,” the original link works again only for people you reinvite to share the item.
