Xcode build fail using UE4.15

Hi, I am using Xcode to build for mac, since upgrading to 4.15 I get many errors and the build fails. It is a team project and older versions used to work when using Xcode however since we moved on to 4.15 I get many errors, perhaps too many to type so I will add screen shots. I am not a coder so please go easy on me. Any suggestions would be appreciated. Many thanks.

Sorted, coder helped me to fix problem so the build is successful. However the project crashes in editor now so I’m looking for solutions for this. Ill get there eventually.
