I have a project on objective-c and am trying to launch it in Xcode 10.

I get this error PrefixHeader.pch.gch 'is not a valid precompiled PCH file

In Xcode 9.4, everything worked without errors.

How I tried to solve the problem:

clean project
reinstall pods
create a new prefix Header - Xcode 10 again changed its extension from .pch to pch.gch

Has anyone come across this? managed to solve the problem?

try deleting your old .pch file and adding a new one. – Shubham Jan 18 '19 at 06:43

Also, precompiled header files have the extension `.pch` not `pch.gch`. – Shubham Jan 18 '19 at 06:48
