I had the same problem and basically did like posted in the comment:
- Remove my account at Xcode / Preferences at the top right.
- open keychain. At the left "my certificates": Delete the Mac or iPhone etc Developer certificate.
- just starting Xcode again and creating a new account like one did when starting Xcode for the first time.

- Change your trust settings of your developer certificate in keychain access to system default
- Delete all certificates in your local keychain
- Quit and relaunch xcode
- Clean
- Run program on device
- When it asks, enter your keychain password and click always trust
The issue could be having your certificate set to always trust, that's the issue I had. If you're getting this warning that stops you from running apps on your device, this should fix everything.

I too had the same error unable to build chain to self-signed root for signer...
My mistake was that I had changed the trust setting of my distribution / developer cert to always trust. When I changed it back to Use system Default it all worked.
回答4:
You are using Distribution certificate instead of Development Certificate if you are able to install app in debug mode but it closes automatically once installation completed.

It is also important to note that the physical device you are trying to deploy to must be listed in the allowed devices list for that provisioning profile -> you can see this here in the tooltip that pops up from your cert information -> you want to make sure that your device is listed in the "Devices" section.
You can add / remove devices when you create the provisioning profile on the apple developer portal website.
