I’m sorry but what you posted doesn’t help. Your first follow-up post is a screen shot and your second is just a repeat of stuff that you put in your original question. I need a crash report. Posting a Crash Report has lots of info on how to get that.

If you post a crash report, I should be able to offer further advice.

ps Quinn’s Top Ten DevForums Tips has a bunch of advice on how to use the forums effectively.

Please check if your NSAppTransportSecurity dictionary in Info.plist is valid. This could be a known issue if you use the wrong type in the dictionary.

I am able to fetch below crash report from the XCode debugger,

I’d still like to see an actual crash report.

If you’re able to catch this in Xcode’s debugger then you can generate a crash report from there. The docs linked to by Posting a Crash Report explain how to do that.

I keep asking for a crash report and you keep posting stuff that’s not a crash report )-: This will go a lot smoother if you actually do that. A crash report will let me quickly understand the context of this failure. The screen shots and bits of debugging snippets you’ve posted so far are very hard to interpret.

Can you please find the crash report file below and do needful

=========================

Thanks for that.

Consider this snippet from your crash report:

Exception Reason: -[__NSCFBoolean objectForKeyedSubscript:]: unrecognized selector sent to instance 0x2031fc390

It indicates that something is trying to treat an NSNumber containing a Boolean value as if it were a dictionary. That’s not good. So let’s look at who that is:

This is all system code. However, frame 5 is interesting. The method name is __sec_protocol_configuration_set_ats_overrides_block_invoke, where the ats indicates App Transport Security. This brings me back to the point my colleague made earlier:

Please check if your NSAppTransportSecurity dictionary in Info.plist is valid. This could be a known issue if you use the wrong type in the dictionary.

The exception backtrace in your crash report strongly indicates that you’re hitting this problem. It’s most likely that the NSAppTransportSecurity property in your Info.plist has a Boolean value where ATS is expecting a dictionary.

What does your NSAppTransportSecurity dictionary look like?

</dict>

but still we are getting the crash please find the below crash report

I’d like to see the Info.plist embedded in your app, just to make sure it matches the values you’ve shown above. Please do this:

1. Build your app.

2. Run it and reproduce the crash.

3. In Xcode, choose Product > Copy Build Folder Path.

4. In Terminal, create a new window and cd to that path:

   % cd "<PATH_FROM_STEP_3>"
   

5. Now cd into appropriate build directory. For example, if you built the app for the device, do this:

   % cd "Products/Debug-iphoneos"
   

6. Dump the Info.plist of the built app:

   % plutil -p "MyApp.app/Info.plist" 
   {
     "BuildMachineOSBuild" => "24D81"
     …
   }
   

   Replace MyApp with the name of your app.

7. Copy that output and paste that into a reply here.

IMPORTANT Use a code block for this output. That’ll ensure it renders nicely. See tip 6 in Quinn’s Top Ten DevForums Tips.

NSExceptionDomains dictionary‘s keys are domains. They are individual domain overrides for ATS. NSExceptionAllowsInsecureHTTPLoads and NSIncludesSubdomains are in a nested dictionary of the specific domain.
