Why do you need Xcode?

Xcode is great because it helps you track logs and look more in-depth at why your app may or may not work. It also allows one-click submission to the App Store and is very efficient due to its being an Apple product.
Requirements
  • Mac OS computer
  • Connected to GitHub
  • GitHub desktop app installed
  • Xcode app installed
  • VSCode installed
  • Apple Developer Account
