Microsoft recently went all-in on the dark mode train, releasing dark modes for Microsoft To Do, the Office suite, and OneDrive. Dark mode for Outlook on iOS shipped just before iOS 13 came out. Now, developers can use the same solution Microsoft used for Outlook within their own iOS apps.

OnMSFT points out that Microsoft's dark mode solution involves an API that doesn't require a lot of code changes. It also allows the dark mode to apply without requiring a person to restart an app.

This is just the latest example of Microsoft open sourcing code. Microsoft continues to show its newer, more open, nature regarding coding.
