There was a problem hiding this comment.
I removed this since DeviceType 3 is used for tvOS, which breaks deployment for iOS.

What does the pull request do?
Implements SaveFilePickerAsync for Avalonia.iOS
What is the current behavior?
Throws an exception saying that Saving Files is unsupported.
What is the updated/expected behavior with this PR?
Allows for saving files on iOS and Mac Catalyst.
How was the solution implemented (if it's not obvious)?
UIDocumentPickerViewController can "export" and "copy" files to a user's device. For it to work, you need to create a temp file that is passed into the picker, set as a copy. The user picks the file name and location to save to. If they follow through, you get an IStorageFile with a URI that can be written to.
It's similar in approach to the MAUI CommunityToolkit implementation, except the file is written to after the fact.
Note that for Read/Write access from outside the App Sandbox, you need to enable
in the info.plist.
