Nativescript localhost http call fails on iOS

Question

I am using Nativescript sidekick cloud build on windows to test my app on iOS - I have also connected my iPhone.

According to this post I am sending my http requests

Answer 1

You can disable the security or add localhost as exception in your info.plist.

<key>NSAppTransportSecurity</key>  
 <dict>  
      <key>NSAllowsArbitraryLoads</key><true/>  
 </dict>

Answer 2

Add localhost as an exception to your app/App_Resources/iOS/Info.plist file to allow insecure (non-HTTPS) communication with the http://localhost domain:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>localhost</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </dict>
</dict>

This is preferable to allowing insecure communication with all domains.

EDIT: Also, remember that you must rebuild your app after editing that Info.plist file! Its changes cannot simply be live-synced or hot module reloaded like JS.
