How to Fix

Resolving Network Request Failures with React Native

When attempting to perform a fetch request within React Native, developers can encounter the error, "Network Request Failed." This occurs due to iOS security restrictions that prevent HTTP requests by default. To remedy this situation, the following steps can be taken:

  1. Understand the iOS Restriction: iOS implements a measure to protect the security and privacy of users' devices. By default, it only allows encrypted HTTPS connections, not unencrypted HTTP requests.
  2. Configure info.plist: To enable HTTP requests for your React Native app, you need to add a specific configuration to your info.plist file. This involves including the following XML code:
<code class="xml"><key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict></code>
  1. Reload Application: Once you've made this modification, rebuild and reload your React Native application. This configuration change will now allow HTTP requests to be sent and received.
  2. Test the Fetch Request: Verify that the fetch request is now successful by sending the same fetch request again. You should no longer encounter the "Network Request Failed" error.
