Xcode 9 - failed to emit precompiled header : <p>I have a project in Objective-C as well as in swift by taking <code>MyProjectName-Bridging-Header.h</code> and i also configured the Objective-C Bridging Header. 
Also i have added 'MyprojectName-Swift.h' in .pch file.</p>

<p>This works fine on xcode 8.2 but when i build my project from xcode 9 i am getting the below error. </p>
