How can a command wait for some action happen ?

[amadeu01]

I would like to make some calls to a webserver and only finish the command after get some answer. How could I achieve this?

@amadeu01 Use something like that:

...
Networking.get(url: url) { result in
    ...handle result here...
    CFRunLoopStop(CFRunLoopGetCurrent())
}

CFRunLoopRun()
print("Ended OK")
