Upgrading to Xcode 8, run my application on iOS 8 simulator crash, although iOS9 and iOS10 are not a problem.

If you have any subprojects within the main project, one of the reasons this can happen is because one or more subprojects have a “ Deployment Goal ” above the main project.

For example, if your main project has an 8.0 deployment goal, set deployment goals for all subprojects prior to 8.0. I think this will fix your problem. Let me know if this happens. Greetings.

I had exactly the same problem after upgrading to Xcode 8, and as @Shaggy noted, in my case this is because the deployment goals in the dependent projects are set to 9.3, while my main project has a deployment target of 8.0.

I had the same problem after changing function arguments in a loaded library. Cleaning up the build directory did this for me.
