[SOLVED]My UI text don't update from script

I have the following script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using UnityEngine.SceneManagement;
6.  
7. public class SceneFader : MonoBehaviour {
8.  
9.     public Image img;
10.     public AnimationCurve curve;
11.     private float _progress = 0f;
12.     public Text loadingText;
13.  
14.     private void Start()
15.     {
16.         StartCoroutine(FadeIn());
17.     }
18.  
19.     public void FadeTo(string scene)
20.     {
21.         StartCoroutine(FadeOut(scene));
22.     }
23.  
24.     IEnumerator FadeIn()
25.     {
26.         float t = 1f;
27.  
28.         while(t > 0f)
29.         {
30.             t -= Time.deltaTime;
31.             float a = curve.Evaluate(t);
32.             img.color = new Color(0f, 0f, 0f, a);
33.             yield return 0;
34.         }
35.     }
36.  
37.     IEnumerator FadeOut(string scene)
38.     {
39.         AsyncOperation operation = SceneManager.LoadSceneAsync(scene);
40.  
41.         operation.allowSceneActivation = false;
42.  
43.         while(_progress < 1f)
44.         {
45.             _progress = Mathf.Clamp01(operation.progress / 0.9f);
46.  
47.             loadingText.text = "Loading... " + (int)(_progress * 100f) + "%";
48.  
49.             //Debug.Log("Loading... " + (int)(_progress * 100f) + "%");
50.  
51.             yield return null;
52.         }
53.  
54.         float t = 0f;
55.  
56.         while (t < 1f)
57.         {
58.             t += Time.deltaTime;
59.             float a = curve.Evaluate(t);
60.             img.color = new Color(0f, 0f, 0f, a);
61.             loadingText.color = new Color(1f, 1f, 1f, a);
62.             yield return 0;
63.         }
64.  
65.         //SceneManager.LoadScene(scene);
66.         operation.allowSceneActivation = true;
67.     }
68. }
69.  

and as the title say, the loadingText don't update to show what is in the function

 

I don't know if this would help perhaps?

Canvas.ForceUpdateCanvases();

 

I put it like this

Code (CSharp):

1. private void OnEnable()
2.     {
3.         Canvas.ForceUpdateCanvases();
4.     }

and no results

 

I think you have to force update AFTER you've edited the text though? if you have multiple changes you would have multiple updates? Just a random guess though

 

still no changes

 

It seems my text was not big enough to display all the content
