Thanks *again*, worked like a charm!

Is there a way to be able to access the data in theList outside the scope of the "do"? Make it available to the entire ViewController?

Thanks SO much for the reply! I had set up the structs and gotten the result as you show, but then had used the JSONSerialzation line further on and tried to run the decode on that. I think I read one too many articles and was overcomplicating it.

Thanks to both of you!

Thanks I'll check that out. When I put the button enable lines in the submitPost code, I get this error message:-[UIButton setEnabled:] must be used from main thread only

Wow thanks for the answer, I had been searching for hours! I am still hitting an error though, I have a few buttons on the view that start disabled, then when the user successfully logs in, the buttons enable.When I putself.button.isEnabled = truein the success case, I get a message-[UIButton setEnabled:] must be used from main thread onlyso I tried to do this: submitPost(post: myPost) { (result) in switch result { case .success(let value): print(value) loginSuccessful = value //...use value here case .failure(let error): print(error) fatalError(error.localizedDescription) } }if (loginSuccessful == "Success"{ //enable Buttons}but while the print(value) does print "Success", I then try to set loginSuccessful to value, but loginSuccessful is "" outside the case and so the buttons never enable..Thanks for the help!
