I am using Xcode for creating a watchOS app with iOS application. When I run my empty application, I am getting the errors below in debug console. I'm not sure why I am getting these errors. 
WatchApp Extension[1722:69488] [default] lookupMainFuncAddressInMachHeader:71: Invalid Swift entry point data
WatchApp Extension[1722:69488] [default] lookupMainFuncAddressInMachHeader:77: Swift entry point address could not be determined.

If you run your app and you get some build errors, that means Xcode has detected that the syntax of your code is wrong. If Xcode is complaining that a specific identifier doesn’t exist, then check that all of your opening curly braces have corresponding closing curly braces.
After the crash, go to Xcode in the lower right hand pane, scroll all the way to the top. So now that you know how to find the actual error message when your app crashes, the next step is to learn to recognize some of the more common types of messages because they will hint at what’s wrong.
You will often see this error if Xcode cannot find the variable or property you are referring to. “Unresolved” means that Xcode couldn’t find something, and “identifier” is another word for a variable, property, function name, etc. Here are several reasons why you could receive this error:
