Summary of some errors in video development using Mac mini devices

The recent real-machine testing, found that the video true function point of the broadcast, the simulator crashed in main, and there is no crash information, which makes me very troubled, no hint, after the person's advice got some methods, hereby share:

Because the crash in main and there is no crash log output, so we can not be judged by the output, so we break the point to debug, step by step, but there is no useful information hint also jumped here:

At this time many people may be inside the collapse, for example I ~ Now, when the breakpoint debugging here we press F8, always press, and observe the console output, and the code jump, I was the console at some point in time the error message appears as follows:

Before that, I have not seen this hint, after translation, this hint refers to the development of hardware problems caused by the device, not our code error, in a word, in short, you put the headset into the Mac Mini to try on it!! \ (^o^)/~ Try it, it's amazing.
