I'm trying to get the same path you'd get by running getconf DARWIN_USER_CACHE_DIR in the terminal, but via

FileManager.default.urls(for: , in:) , but can't really find out how is there a way to do that other than running the shell script via swift?

It's done like this:

let cachesDirectory = Filemanager.default.urls(for: .cachesDirectory, in: .userDomainMask).first

let darwinUserCacheDir = cachesDirectory!.appendingPathComponent("com.apple.darwin.user-cache", isDirectory: true).absoluteString

If you want exactly that value, it’s not hard to call confstr from Swift:

func darwinUserCacheDir() -> URL? {
    var buf = [CChar](repeating: 0, count: 1024)
    let success = confstr(_CS_DARWIN_USER_CACHE_DIR, &buf, buf.count) >= 0
    guard success else { return nil }
    return URL(fileURLWithFileSystemRepresentation: &buf, isDirectory: true, relativeTo: nil)
}

Keep in mind that these values can diverge based on the context in which the code is running. For example, if you run this code in a sandboxed app you’ll get a very different result.
