Is there an example of the implementation of logic games like "Three in a row" in Swift?

Question

Game development

Maybe someone in the know, where you can read or see about logic or a "live" example of the implementation of games like 'three in a row'?

ps a game in which it is necessary, fruits, crystals, figures, etc., to line up 3-4-5 elements horizontally or vertically, they burn out, and new ones fall in their place from the top, like Tetris.

Thanks in advance!

For example , the code is already outdated, but you will understand the algorithm anyway
