Description

When using Hyperloop I am trying to get the NSThread callStackSymbols It is supposed to return an NSArray, but I am getting an object with key as $native. I have tried casting, create a new NSArray from the data etc but I am completely unable to use the data. Steps to reproduce: 1. Create new alloy hyperloop enabled project 2. In alloy.js, put this:

var NSThread = require('Foundation/NSThread');
var crashStackTrace = NSThread.callStackSymbols;
Ti.API.log(Object.prototype.toString.call(crashStackTrace));
Ti.API.log(Object.keys(crashStackTrace));
Ti.API.log(Object.values(crashStackTrace));

This logs out as:

It returns an NSArray instance that needs to be accessed via objectAtIndex. Working example:

   var NSThread = require('Foundation/NSThread');
   var win = Ti.UI.createWindow({ backgroundColor: '#fff' });
   
   var btn = Ti.UI.createButton({
       title: 'Test'
   });
   
   btn.addEventListener('click', function () {
       try {
           btn.crash();
       } catch (e) {
           var crashStackTrace = NSThread.callStackSymbols;
   
           for (var i = 0; i < crashStackTrace.count; i++) {
               Ti.API.warn(crashStackTrace.objectAtIndex(i));    
           }
       }
   });
   
   win.add(btn);
   win.open();
