One of my developer is asking me to export my Apple Distribution certificate and key from my Keychain and send it to him. He claims he need this to run the app we are developing on his device. I am concerned about sharing this certificate. what should I do? is there an alternative way which does not involve sharing the certificate?
Developer will need the Apple Development Certificate to run and debug the application in the device. You can use TestFlight for Testing purpose but for development one will need the certificate.
If the functionalities of the application doesn't require device then the app can be used in the simulators as well.
