Build Error

[eddyteddy3]

I am using Xcode 11 beta 6. I successfully installed pod files but when i tried to run it on physical device it gave the following two errors.

"No signing certificate "iOS Development" found: No "iOS Development" signing certificate matching team ID "9KDW35V6BS" with a private key was found. (in target 'ASMediaStream_Tests')"

"No account for team "9KDW35V6BS". Add a new account in the Accounts preference pane or verify that your accounts have valid credentials."

I tried signing the accounts again but didn't help.

What should i do to fix it?

"Could not find or use auto-linked framework 'WebRTC'"
