Use:

NSURLSessionConfiguration:backgroundSessionConfiguration:
instead of

NSURLSessionConfiguration:defaultSessionConfiguration
From the NSURLSessionConfiguration:backgroundSessionConfiguration: documentation:

Upload and download tasks in background sessions are performed by an external daemon instead of by the app itself. As a result, the transfers continue in the background even if the app is suspended, exits, or crashes.
So in your case, change:

vsouza

# Set variables in .bashrc file

# don't forget to change your path correctly!

export GOPATH=$HOME/golang
export GOROOT=/usr/local/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin
