Error: Unrecognized font family Material Design icons after installing react-native-elements?

If you are coming from react-native 0.60+ so please add the UIAppFonts (below mention) in info.plist file . And drag and drop the fonts folder under node_modules/react-native-vector-icons to the project in xcode. Make sure your app is checked under "Add to targets" and that "Create groups" is checked if you add the whole folder.

<key>UIAppFonts</key>
<array>
  <string>AntDesign.ttf</string>
  <string>Entypo.ttf</string>
  <string>EvilIcons.ttf</string>
  <string>Feather.ttf</string>
  <string>FontAwesome.ttf</string>
  <string>FontAwesome5_Brands.ttf</string>
  <string>FontAwesome5_Regular.ttf</string>
  <string>FontAwesome5_Solid.ttf</string>
  <string>Foundation.ttf</string>
  <string>Ionicons.ttf</string>
  <string>MaterialIcons.ttf</string>
  <string>MaterialCommunityIcons.ttf</string>
  <string>SimpleLineIcons.ttf</string>
  <string>Octicons.ttf</string>
  <string>Zocial.ttf</string>
</array>

Try running following command -

react-native link react-native-vector-icons

if this does not solve your problem then once rebuild your app using,

react-native run-ios

sometimes CLI is not able to get the updates automatically.

Just add these lines in info.plist, delete the build/ folder inside ios folder and rebuild the app npx react-native run-ios It worked for me.

<key>UIAppFonts</key>
<array>
  <string>AntDesign.ttf</string>
  <string>Entypo.ttf</string>
  <string>EvilIcons.ttf</string>
  <string>Feather.ttf</string>
  <string>FontAwesome.ttf</string>
  <string>FontAwesome5_Brands.ttf</string>
  <string>FontAwesome5_Regular.ttf</string>
  <string>FontAwesome5_Solid.ttf</string>
  <string>Foundation.ttf</string>
  <string>Ionicons.ttf</string>
  <string>MaterialIcons.ttf</string>
  <string>MaterialCommunityIcons.ttf</string>
  <string>SimpleLineIcons.ttf</string>
  <string>Octicons.ttf</string>
  <string>Zocial.ttf</string>
