`MacCatalyst` support

[mhrastegari]

I'm trying to add MacCatalyst support to your library from mostly using your existing iOS code.
I've been successful for implementing ScreenRecordingProtection but not ScreenshotProtection!
And it's like there's nothing for it on internet :)
Do you have any suggestion or tip that can help for implementing ScreenshotProtection on macOS so can I submit a PR for it?

Hi @mhrastegari, Thank you for your contribution 😀

Unfortunately, I don't have a proper answer for you right now. When I created this package, I tried to include support for MacCatalyst, but I couldn't figure out how to make it work properly. Apple docs for MacCatalyst are awful and the most common explanation is that MacCatalyst apps work like an iPad app embedded into MacOS.

As a suggestion, you could try using the ObserveUserDidTakeScreenshot notification or the UIScreenshotService provided by Apple (I don't know if it's available on Maui) to see if you can do something with it. Some people suggest using them to detect and delete the screenshot from the user's device, but I think this approach is really invasive and probably would mess with some privacy policies or something.

SOOO awful 😣 even on native swift communities I couldn't find anything for MacCatalyst.

Oh I saw them too and to be honest that is too hacky and like you said messes with some privacy policies.

@mhrastegari @FabriBertani according to apple own representatives they say there is not such api which will allow you to prevent screenshot. i has been asked from apple a number of times but they simply denied to expose it to developer. according to some veterans there exist an API but apple is holding it back due to blue ray support. i don't know why apple is doing this kind of behavior

@mhrastegari even if you have implemented screen recording protection it is huge if possible please submit a pr for this. but have you considered google meet screen sharing or any other such services?

Hi @Akash-github-project
Like you mentioned, since there's no Screenshot API I don't think it would be a good idea to add an incomplete support for MacCatalyst! although it's all up to the owner of the library to decide!

For Screen recording implementation you can see it in my fork:

@Akash-github-project as you mentioned, there is no official support from Apple for this, so I will not add it to this plugin until that situation changes, mostly because users can face store rejection by Apple for violating privacy rules (probably) and stuff like that.
