how to download facebook and youtube ios 12.

If you have an iPhone 5s, 6, or 6 Plus that cannot update any further than iOS 12, and you need to run modern apps, it is time to buy a new iPhone, preferably one that will be compatible with iOS 18.

The iPhone 5s came out about 11 years ago. The iPhone 6 and 6 Plus came out about 10 years ago. All three have only 1 GB of RAM. No iPhone capable of running iOS 15 or later has that little.

You don't. The developer of the app makes the choice on what iOS version they want to support and can drop an older version anytime they wish.
