Unity www class crashes on iOS 64 bit
I just built an application for iOS 64 bit using unity 5.1, xcode 6.4. I'm calling a Rest API with some headers inside. But the application crashes on this www call.
The crash point is somewhere in FeedUnityWebStream which is an assembly file, hence no help from crash point. Crash log has some entries of CFNetwork library.
This API has been working fine on 32 bit build.
Please help
Api Call
string url = "http://gamelootnetwork.com/apis/RestServer.php/";
WWWForm form = new WWWForm();
form.AddField("method","imatrixLogin" );
form.AddField("imatrix_id", strEmail);
form.AddField("password", strPassword);
WWW www = new WWW(url, form);
loading = DashUpUtil.showLoadingIndicator(transform.parent);
StartCoroutine(WaitForRequest(www));

In case you haven't already, be sure to officially report this as a bug (in addition to posting here to help narrow down cause/find workarounds) so that it can be fixed in Unity itself.
@faizie Was this ever resolved? I'm getting a similar crash using 5.3.4p1 under some pretty specific circumstances, though my crash is happening in a different thread and has slightly more stack available above FeedUnityWebStream.
For me the problem was that I had disabled ARC in Xcode. When I enabled it in build settings, the problem was solved. Go to "Build Settings", Look for "Apple LLV$$anonymous$$ 7.0 - Language - Objective C" Under that menu, select "Yes" for "Objective-C Automatic Reference Counting"
Add -ObjC in linker flag and enable ARC in build Settings.
If you get some other errors because of ARC enabled then....
You can disable ARC for a specific class using the -fno-objc-arc compiler flag. In Xcode, go to Target --> Build Phases tab --> Compile Sources group.
Double-click the file for which you want to set the flag, enter -fno-objc-arc in the pop-up panel, then click Done.
(This might not a direct answer to your question) I've been using Best HTTP instead of Unity's WWW for about 2 years. Never had any issue with it so far.
