问题
I have .p12 file of ios Development certificate, I want to import it into my login keychain. But when I double tap it goes inside certificates instead of MyCertificates and it doesn't have expand arrow.
Because of this, I am not able to archive my iOS project. While codesigning I am getting an error saying "The specified item could not be found in keychain". keychain after importing p12
And I also cant see any private keys for my system keychain certificates(cant see the expand arrow). Please help.
