I have the same issue, but I can't find "prebuild nativescript" in my Build Phases. I just find "Output Files" in another places, like [CP] Copy Pods Resources and Embed Pods Framework. My path is different but I guess is the same problem. Error: error build: Build input file cannot be found: '/Users/Guilherme/Documents/VisionWithRoom/DerivedData/VisionWithRoomExample/Build/Products/Debug-iphoneos/VisionWithRoomExampleObjC.app/VisionWithRoomExampleObjC'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it?
