I have been developing a project that was able to be built fine on iPhones up until I updated Xcode. Now the only option I have as destination simulators is iPads. I have done things like change the development target to a specific version of IOS but this has done nothing for me. I believe I was able to build on the iPhone once after I updated Xcode. This problem really started when I was fiddling with settings trying to fix a bug with my companion app saying the ios app was not installed. With that aside, the only setting I changed was in target of WatchKit extension and was called App can run independently of companion iPhone app I changed it from "YES" to "NO". But after the app wouldnt run I changed it back. After that I was no longer able to build IOS on iPhones. It seems like an unrelated option for destination paths but I thought I would include it. I also did searches through build settings while looking for target stuff becuase I was confused at first. But I did not change any build settings that I know of.
