Your account already has a signing certificate for this machine but it is not present in your keychain

Question

I get this error, verbatim, when trying to build and install to a device.

This is my environment:

• Xcode 8
• El Capitan

Has anyone run

Answer 1

Go to Xcode Preferences -> Accounts tab -> Double-click your team name -> Click the + at the bottom left of the dialog box that appears -> Select iOS Development.

This will create a new development certificate that will allow you to install and test on your device.

Answer 2

In my case problem was in revoked certificate.
To fix this problem:

1. Go to Xcode –> Preferences –> Accounts –> Select needed Apple ID –> Double-click your Team –> Check certificate with Status Revoked.
2. Go to Keychain Access –> Search for certificate was revoked –> Delete it.

Answer 3

I got this error immediately after a repair to replace the MagSafe module on my MacBook Pro (I am guessing the long period with the battery unplugged reset the SMC). I really didn't want to recreate the signing certificate so I went into the Keychain, realised I had so many expired keys still present and decided to delete the expired ones. I Go back to Xcode, clean the project and rebuild and boom...everything works fine. Hope this helps someone

Answer 4

go to your apple developer site and download the signing certificate. Once downloaded you should be able to click and it will auto do its thing and should be good after that
