Why isn't ProjectName-Prefix.pch created automatically in Xcode 6?

Without the question if it is proper or not, you can add PCH file manually:

Add new PCH file to the project: New file > Other > PCH file.

At the Target's Build Settings option, set the value of Prefix Header to your PCH file name, with the project name as prefix (i.e. for project
named

TestProject

and
PCH file named

MyPrefixHeaderFile

,
add the value

TestProject/MyPrefixHeaderFile.pch

to
the plist).

TIP: You can use things like

$(SRCROOT)

or

$(PROJECT_DIR)

to
get to the path of where you put the

.pch

in
the project.

At the Target's Build Settings option, set the value of Precompile Prefix Header to

YES

.
