i was also facing this issue for the past 2 months. atlast we changed to https .
today too when i checked issue still there but i tried many steps and,
Fixed the issue now.
steps.
remove your existing http request checking code in info.plist
add this
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>localhost</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
</dict>
</dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
then Xcode -> product -> Clean Build folder
then run the app in your iOS device.
Now we can run your http urls in your ios as you needed .
