Found in diagnostics on an iPhone 6s Plus. Any idea what it means?
If you look at the exception code that points to:


  0x8badf00d: Reads as “ate bad food”! (If you squint your eyes and replace the digits with alphabetic characters. :p) This code indicates that an application was terminated by iOS because a watchdog timeout occurred. Basically, the application took too long to launch, terminate, or respond to system events.


There's a nice article explaining this.
