I have suffered from this problem for a couple days. Basically I have tried every way which can be found on the internet but none of those was helpful indeed. I even reinstalled Xcode two times (Xcode 8.3.2 8E2002, simulator iOS 10.3 14E269). And of course, there was nothing wrong with my project, scheme and empty settings.. everything seems normal. Finally I found that the best way to solve this is before you deploy your app to the simulator, you should clean your project (shift + cmd + K) and then you run again (cmd + R). This will solve your problem.
