This change will come starting next year.
Apples Lightning port has almost come to an end.
However, the tweet doesnt say 2023, but we can expect it to happen along with iPhone 15.

Portless iPhone may cause more problems due to current limitations of wireless technologies & the immature MagSafe ecosystem.2.
According to Kuo, USB pop in-C will improve the transfer and charging speeds of the iPhone.
Ming-Chi Kuo also clarified about the Apple creating an iPhone with no ports.

He said such a rig would create a lot of problems.
The USB-C chargers are a little bit thicker than Lightning connectors, but it comes with an advantage.
It offers faster charging, and data transfer speeds than Apples connector.

There are third-party accessories including chargers and adapters, which uses the Lightning connector.
So, the third-party manufacturers of these accessories will be forced to switch.
However, the exact reasons behind this new change by Apple are not known.
