xcode - iOS Simulator not connecting to web service -


i developing cordova project on xcode.

am using cordova v5.4.1, xcode v7.2 , ios simulator v9.2.

the app building , deploying on emulator rest web services not being consumed. able view json response web service in emulator's safari browser, app not show same.

i have enabled "allow http services" in developer settings , tried restarting emulator , xcode, nothing helps. have added these lines config.xml.

<plugin name="cordova-plugin-whitelist" spec="1" /> <access origin="*" />

how can issue fixed?

maybe you're getting blocked ios 9 ats (app transport security)?

to test if case, try on mac, using terminal.app:

nscurl --ats-diagnostics https://api.your-server.com

if ats allow connecting https://api.your-server.com, should see this, in first block of response:

default ats secure connection --- ats default connection result : pass ---

anything else means ats block http(s) requests going through.

to resolve this, can either fix issue @ root (use https tls 1.2, sha256 or better, , forward secrecy), recommended solution, not possible, or define exception server allowed in app-info.plist file. example:

<key>nsapptransportsecurity</key> <dict>     <key>nsexceptiondomains</key>     <dict>         <key>api.your-server.com</key>         <dict>             <key>nsexceptionminimumtlsversion</key>             <string>tlsv1.1</string>             <key>nsexceptionrequiresforwardsecrecy</key>             <false/>         </dict>     </dict> </dict>

more info on ats, , values can use define exceptions: https://developer.apple.com/library/prerelease/ios/documentation/general/reference/infoplistkeyreference/articles/cocoakeys.html

if else fails, can try use cordova plugin: https://github.com/robertklein/cordova-ios-security don't recommend it, disables ats, pretty-bad-idea™.
