Is it possible to disable ATS in iOS 9 just for debug environment?

Question

I\'m working on a development environment without HTTPS setup. Is it possible to automatically disable ATS just for the development (debug) mode?

Answer 1

Yes, you can configure your project settings to use different Info.plist file for Debug, Release or whatever configuration you use in your project (similar to the way Provisioning Profiles are set), so in your Debug plist you can disable ATS totally.

Go to Project -> Your Target -> Build Settings -> Info.plist File

Answer 2

My solution is to keep ATS disable option at the default NO value and add a New Run Script Phase to change it in the app bundle's Info.plist when building the app.

This is the script:

#Disables ATS in debug builds.
INFOPLIST="${TARGET_BUILD_DIR}"/"${INFOPLIST_PATH}"
case "${CONFIGURATION}" in
"Release"|"Adhoc")
/usr/libexec/PlistBuddy -c "Set :NSAppTransportSecurity:NSAllowsArbitraryLoads NO" "${INFOPLIST}"
;;
"Debug")
/usr/libexec/PlistBuddy -c "Set :NSAppTransportSecurity:NSAllowsArbitraryLoads YES" "${INFOPLIST}"
;; 
esac

Answer 3

Another solution. By using INFOPLIST_PREPROCESS = YES and INFOPLIST_PREPROCESSOR_DEFINITIONS = DEBUG=1,

it can be conditional preprocess like C code using #ifdef or #if directly in Info.plist.

<key>UIMainStoryboardFile</key>
<string>Main</string>
#if DEBUG
<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>
#endif
<key>UIRequiredDeviceCapabilities</key>
<array>
