Hello,

Our project compiles fine in Xcode 9.4.1, but upon moving to Xcode 10, a framework we are compiling for use in our main app fails to compile with the following error pointing to a large number of files. Below is a small sample of what we are seeing.

<unknown>:0: error: duplicate input file 'WatchKit'
<unknown>:0: error: duplicate input file 'App'
<unknown>:0: error: duplicate input file 'WatchKit'
<unknown>:0: error: duplicate input file 'App'
<unknown>:0: error: duplicate input file 'Files'
<unknown>:0: error: duplicate input file 'Files'

I am at a loss for how to address this problem. If anyone else has run into this problem and found a fix, I would greatly appreciate it.

Did you perform a clean build folder first ?

Then, for each file in the project, I would check what targets are defined in the files attributes inspector.
