FileManager.default.copyItem throws error "The file doesn't exist"

reno_queen

I am a beginner at SwiftUI and my practice code repo is here. I am trying to use LLMFarm Core to create a local LLM. While trying to run this code try FileManager.default.copyItem(atPath: temporaryURL.path, toPath: fileURL.path) I'm getting the error which I'm guessing comes from the temporaryURL variable: Error: The file “CFNetworkDownload_rr8uC6.tmp” doesn’t exist. This is what my code function looks like status = "downloading"...

Great question — answering as the UphillTech team:

It looks like FileManager.copyItem(atPath:toPath:) is throwing a misleading error. The temporary file does indeed exist at temporaryURL . However, the destination directory, file:///Users/salman/Library/Containers/com.guinmoon.LLMFarm23/Data/Documents/models , does not exist. Since copyItem(atPath:toPath:) does not automatically create directories needed for new files, the attempt to copy the file to fileURL is failing. Before beginning the download, create the models directory by calling try FileManager.default.createDirectory(at: fileURL.deletingLastPathComponent(), withIntermediateDirectories: true) , and the copy operation should succeed.
