Warning on my first Hello World App, please guide


So as I was just making my first hello world app , I keep getting this warning -

libMobileGestalt MobileGestalt.c:890: MGIsDeviceOneOfType is not supported on this platform.

My only concern is that this warning may become an error as I move ahead , why was this not there earlier in playground but seems to be here ... kindly guide


Below is my project setting snap -

This is just log noise. If it really bothers you then please do file a a bug report about it, but I’m quite certain that it won’t cause you any runtime problems.

Note that I’ve pointed you to Apple Bug Reporter, not the Swift bug site, because this message is coming from something deep in iOS (well, in your case the iOS Simulator). Also, if you do file a bug, please post your bug number, just for the record.

Share and Enjoy

@eskimo - thanks, I was under impression that I had made some wrong setting , I can now move to next section, I have bookmarked the link to file bug report , will use it if I find such issues ...
