Answer 1

Xcode to 7.3

I have encountered this issue when archiving and in my case, downloading all provisioning profiles on preferences cant fix this so I update it.

Try to check your app's Provisioning Profile on Member Center.

Go to Developer > Certificate, IDs & Profiles > Provisioning Profiles > All

Look for your app's Development and Distribution Profile, check if status is Invalid then Edit,

Modify your profile contents and select the Generate button to save changes

Finally, Go to Xcode> Preferences > [Apple account] > View Details and Download All to refresh your provisioning profiles

Clean. Build. Archive. Success ! Hope it helps :)
