I know you seen this error alot of times as did I, but I tried every solution I found and non of them worked for me
I updated my Xcode
to the last version 10.2.1
.
I updated the cocoapods
and the pods in the project.
I even tried to lock and unlock the keychain Access
.
I don't know what to do now, this is the last solution I got to ask you here.
