Error when compiling with Xcode?

[D-an-W]

I just downloaded the latest build (Thanks for the continued development!) and seem to have a problem when trying to compile with Xcode that prevents the process completing?

File '/Users/Me/Downloads/HWSensors-master/GPUSensors/GPUSensors-Prefix.pch' has been modified since the precompiled header was built

It could be me doing something wrong but I used the same method as I did yesterday that worked.
