IOS is unable to fetch data using $http.get() method

Ionic Framework ionic-v3
1

Hi,

I am trying to fetch data using $http.get() method for hybrid app. This method is perfectly working for browser, android but not for ios. I know about TLS policy, so i have used secured server for this. I got too many post to add following code to Info.plist file

<key>NSAppTransportSecurity</key>
<dict>
   <!--Connect to anything (this is probably BAD)-->
   <key>NSAllowsArbitraryLoads</key>
   <true/>
</dict>

But this piece of code is already there in the plist. I have also tried to modify the plist file but whenever i run ios project, this file is getting overwrite with default code. I am running with ios 10.

I have noticed one more thing that i am fetching data from local server i.e https://192.168.XXX.XXX in this case i am unable to fetch it with following error :

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)

but whenever i use https://www.mydomain.com then it works perfectly.

Where i am wrong ? Please suggest me a way to get ride of it.

Thank you.
