Xcode build fails, How to ?

Hi guys,

I’m creating iOS game, but after I build it in Unity, open with Xcode and trying to build it says : The identity 'iPhone Developer' doesn't match any valid, non-expired certificate/private key pair in your keychains

Could you help ?
Thanks in advance !

This is not a Unity problem, but your own iOS one. You need to make sure your Code Signing Identity, provisioning profiles, and bundle ID are all in working order. It sounds like your bundle ID and provisioning don’t match.
