What are the differences between Pokémon Sword and Pokémon Shield for Nintendo Switch?

Why do Pokémon games release as two separate versions?

Pokémon's tagline may be "catch 'em all," but historically, it was impossible to do so with only one version of the game. Ever since it's inception, Game Freak usually releases two main Pokémon RPGs alongside each other. From Red and Blue, Ruby and Sapphire, Diamond, and Pearl, the series has stuck with these dynamic duos. For the most part, you're getting the same experience. However, each tends to have its own handful of exclusive Pokémon and a unique legendary that can only be caught in that version of the game. In Pokémon Let's Go players even had unique starter Pokémon between Eevee and Pikachu. Ruby and Sapphire, in particular, featured two separate villainous teams with Team Magma and Team Aqua, which were the region equivalent of Team Rocket.

What are the differences between them?

There are several Pokémon exclusive to Sword or Shield. You'll need to trade with friends or people online to collect them all. Note, that you need a Nintendo Switch Online membership in order to do online trading. Here's a collection of all of the Pokémon exclusive to either game:

Version exclusive evolutions

You'll find Applin in both Sword and Shield. However, it will evolve into a different Pokémon depending on which version of the game you have. To be more specific, in Sword, you have to give Applin a Tart Apple to make him evolve, while in Shield, you need to provide him with a Sweet Apple.
