Why does the iPad2 simulator work, but the iPad Retina and iPad Air don't work?

I'm a beginner in iOS development, but I'm trying to develop universal apps that work with iPhone and iPad without using storyboard.If you select iPhone and iPad2 in the simulator and start it, it will start without any problems, but if you select iPad retina and iPad Air, you will get an error when starting it.

What is the possible cause of the error from this information?
Personally, I feel that I made a careless mistake related to the setting...
Please let me know if there are people who have similar symptoms and have been able to solve this problem.

}

Xcode6 removed armv7s from Standard Architectures and
If you want to run on iPad Air, you will need to manually add settings to Build Settings ->Architectures.

I don't know the details, but I think the architecture configuration during the build was also a mistake. The XCode build configuration item has an entry called Valid Architectures. Perhaps armv7 is set.

For iPhone 5 and later models, a Apple A6 CPU or later is used.This corresponds to an architecture called armv7s, so I think this may be the cause, but I'm not sure.

I found a solution, so I'll write it here

I built it after setting it to iPad only instead of universal, and then I put it back to universal setting and built it, and it started working.I don't know the cause, but now it works.

Based on what @KeiMinagawa wrote in the questionnaire, this post was posted as a separate response on the community wiki.
