Program ended with exit code: 87

Does anyone know what this exit code refers too. Google isn't helping much.
UPDATE: I have found that this was being caused when I was trying to call 
[mutArray objectForIndex:indexpath.row]

and the index was outside the range of the array. 
The stacktrace didn't include anything else besides the code 87 message. Also the console window didn't even slide up when the app crashed. Not very useful I guess. Anyone know how to make it more useful in these situations?

A:

"Anyone know how to make it more useful in these situations?"
First, use CMD-SHIFT-R in XCode to show the console window.  You should have seen an error message about accessing an array with an out of bounds index.
Also, use CMD-Y to build & debug (vice CMD-R to build & run) your app.  If it crashes, you will be in the debugger (CMD-SHIFT-Y for debug window) with the exact line of code that crashes, as well as a stack trace, all your variables, etc.

 Q:

iOS - Get current Wifi credentials (SSID & password)

I recently bought a smart personal scales including an iOS-App.
While doing the wifi-setup of the scales on my iPhone, iOS asked me to allow this App to hand on my credentials of my current Wifi-network, I was logged in. I was looking for this feature quite intensive but without success, because I'd also like to just hand it on to another device to connect it to Wifi.
How can I do this in my App to fetch the Wifi credentials?

A:

I believe this functionality is built into the HomeKit / MFI frameworks and it not a usable API. 
See the documentation here
So you can use the API to look for devices that aren't currently configured and configure them on your device. The underlying frameworks may share additional information but you wouldn't be able to request this information from another application as there isn't any public methods for it and it would definately be a security risk anyway.
