I'm also getting this duplicate tasks error: Target 'TrashQuest' (project 'TrashQuest'): CoreMLModelCompile /Users/kmcph3/Library/Developer/Xcode/DerivedData/TrashQuest-glvzskunedgtakfrdmsxdoplondj/Build/Products/Debug-iphonesimulator/TrashQuest.app/ /Users/kmcph3/Desktop/FinalTrashQuest/TrashQuest.swiftpm/TrashDetector 1.mlmodel

Never mind guys, I figured it out. I compiled the model using Terminal, created resources and sources folders, and played around with the package.swift file, and eventually got it to work.
