Multiple codesigning identities (i.e. certificate and private key pairs) matching were found

Question

Code Sign error: Multiple matching codesigning identities found: Multiple codesigning identities (i.e. certificate and private key pairs) matching “iPhone Developer: Coders (4B4R89J5KK43GU33E64I4347VZ)” were found
CodeSign error: code signing is required for product type 'Unit Test Bundle' in SDK 'iOS 8.0'

I am unable to test the app on the device.

I also imported the .developerprofile file from my teammate, and was able to upload the app to app store, but cannot test app on device.

In keychain all the certificates are valid.

I tried to deleting iOS Provisioning Profiles.

I also refreshed my setting using these steps

• In Xcode Preferences
  • > In Accounts click on your Apple ID
  • > Click View Details
  • > Click on your projects Provisioning Profile
  • > Click refresh button bottom left

Clean and build again, but still facing the same issue not running on device.

Make sure you don't have duplicate Certificates in Keychain Access in your Mac. To check this open Keychain Access and within "My Certificates" check that you don't have duplicate certificates, if this is your case, remove the duplicates.
