Face ID (iOS)

iOS 11 added support for Face ID and was first supported by the iPhone X. The developer needs to provide a value for NSFaceIDUsageDescription, otherwise your app may crash.

You can provide this value (the reason for using Face ID) by adding something like this to App/info.plist:

<key>NSFaceIDUsageDescription</key>
<string>For easy authentication with our app.</string>
