I want to build very simple code using Structure SDK. However, I get an error (see below)

Code :

import UIKit
import Foundation

class ViewController: UIViewController {

    override func viewDidLoad() {
        if (myclass.isConnected() == true){
            myTextView.text = "Exist."
        }
        else{
            myTextView.text = "Not Exist!"
        }
    }

    @IBOutlet weak var myTextView: UITextView!

    var myclass = STSensorController()
}

Error:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_STSensorController", referenced from:
      objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Please help me debug

Clean code with this command shift + option + command + k. If this fail, make sure your STSensorController class have reference in module.

  • Did you mean not ‘swift’ but ‘shift’? Also, can you explain more about “Make sure your STSensorController class have reference in module.”? I also think that there is a problem about STSensorController... – youjung Jan 15 '19 at 07:43
