Unlike the Android version of Facebook Cloud Gaming which can be accessed through the Facebook Mobile application directly, the iOS version of Facebook Cloud Gaming cannot do that.
The reason is because Apple does not allow games that run in an application.
Games on Apple's iOS operating system must be released in the App Store.
If this can not be done, then the game can be released in the web version, so that later iOS users can access it through the Safari browser.
This is what Facebook did, where they released Facebook Cloud Gaming for iOS in the web version so that the games on the game streaming service can be accessed through the Safari browser.
This step made by Facebook is arguably similar to what was previously successfully done by Microsoft xCloud Gaming version of iOS.
Microsoft also released their iOS version of xCloud Gaming in the web version, so it can be accessed through Safari.
Meanwhile, to be able to access Facebook Cloud Gaming, iOS OS users must visit a special link.
The special link will directly direct iOS users to the main page of the Facebook Cloud Gaming web.
There, there are various kinds of games that can be played by iOS OS users.
As explained earlier, iOS users can access and play games on Facebook Cloud Gaming through the Safari browser.
