Problems after upgrading to Xcode 10: Build input file cannot be found

Question

I upgraded my Xcode SDK to version 10 last night and then find I cannot build.

I\'m getting this error:

Build input file cannot be found: \

Answer 1

In my case I had a build script that generated the .app binary (Buck). The Buck build script ran in parallel with Swift Embed build step. Because the .app binary was not generated yet the Swift step would fail.

In my build script I added "$BUILD_PRODUCTS_DIR/$EXECUTABLE_PATH" under "Output Files".

This tells Xcode's New Build System that this script will output the app Binary and in turn Xcode will make sure to synchronize any build steps that depend on this artifact.
