Swift 3.0 unresolved identifier for DispatchQueue

Question

I have been trying to find the answer to this for hours now but still no avail. I am trying to use the following code:

func fetchPosts() {
    ref.child(\"Amore\         


        

Answer 1

Recently, a simple swift script I had written was yielding this error when I ran it under Linux. The same script had worked fine under macOS.

Out of curiosity, I added an 'import Dispatch' to the top of the script and it then ran fine on Linux.
