Summary: The `||=` operator in an expression like `x = a ||= b` works in a way that: - if a is null, it assigns b to x - if a is `falsy`, it assigns b to x - otherwise, it assigns a to x. In our setup, if the user set `hermes_enabled` to `false` in the Podfile (one of the suggested way to disabled Hermes), the `options[:hermes_enabled]` part will evaluate to false and, therefore, `hermes_enabled` will obtain the value of `true`. ## Changelog [iOS][Changed] - Use the correct operator to decide whether Hermes is enabled or not.
