upgrade - 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: '/Users/call01/Library/Developer/Xcode/DerivedData/Comp-Lite-Apps-gytvmossqptokeafrddvvmnlzadk/Build/Products/Debug-iphoneos/SG11.app/SG11

which did not exist before my upgrade and I'm tempted to revert back but would like to stick with version 10 if I can resolve this issue.

Answer 1

Try to switch back to the Legacy Build System (File > Project Settings > Workspace Settings > Legacy Build System)
