Note I am already unlocking the keychain. Solution: The Key used by ${codeSignIdentity} “iPhone Distribution: My Company” Certificate does not have Access Control granted to codesign

1. Open your keychain in Keychain Access
2. Select Certificates category
3. Maximize so you can see the Key under the Cert
4. Double click the key then select “Access Control”
5. Ensure codesign is listed in the “Always allow access by these applications:”

— If it is not:

1. Click the +
2. HitG & in the popup window, enter /usr/bin then click Go
3. Select codesign & click Add
4. Click Save Changes then enter your password
