 ## Usage
 
+### Xcode 27
+
+1. Copy your preferred `.xcworkspacecolortheme` files from [`themes/xcode-27/`](./themes/xcode-27/) to `~/Library/Developer/Xcode/UserData/FontAndColorThemes/`. Create the folder if needed and back up any existing files with the same names.
+2. Open **Xcode → Settings → Appearance → Theme → Choose…** and select your theme. Use Light appearance for Latte and Dark for the other flavors. Restart Xcode if the new themes are not listed.
+
+These native themes preserve exact palette values and leave fonts and cursor shape unchanged. Copy the files directly rather than using the classic-theme importer. See [Xcode 27 compatibility, coverage and development notes](docs/xcode-27.md) for tested builds and remaining limitations. The previews above show the existing legacy themes.
+
+### Earlier Xcode versions
+
 1. Copy your preferred flavor(s) from [`themes/`](./themes/) to `~/Library/Developer/Xcode/UserData/FontAndColorThemes`.
 2. Go to **Xcode** > **Preferences** (<kbd>Command</kbd> + <kbd>,</kbd>), choose the **Themes** tab, and select your desired Catppuccin theme.
