Alamofire: [Alamofire 5] po command in LLDB is not working

[himaratsu]

• [-] I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

In Alamofire 5, We can't use po (expr) command in LLDB for debugging.

What did you expect to happen?

@IBAction func didTapButton(_ sender: Any) {
    AF.request("https://httpbin.org/get").response { response in
        debugPrint(response)    // <= breakpoint here
    }
}

When typing po response at the breakpoint,, we expect to be shown the content of response.

What happened instead?

This error message was given.

error: Couldn't materialize: can't get size of type
error: errored out in DoExecute, couldn't PrepareToExecuteJITExpression

Yes, I've noticed this too. It seems to be a bug in lldb or Xcode's use of it. I suggest you file a bug with Apple.

I'm getting same problem tryng to debug my application using alamofire ; is there a fix ?

[jshier]

@atrebbi No fix yet, still broken from lldb. Alternate debugging approaches like expr print(variable) might work, depending on the scenario.
