Camera boundaries

I'm trying to set boundaries so the the camera doesn't show outside of the tilemap.
My code for the camera is below.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class CameraFollow : MonoBehaviour {
4.     public Transform target;
5.     public float camSPD = 0.125f;
6.     public float xMin = -1;
7.     public float xMax = 1;
8.     public float yMin = -1;
9.     public float yMax = 1;
10.  
11.     Transform t;
12.  
13.     void Awake () {
14.         t = transform;
15.     }
16.  
17.     void LateUpdate () {
18.         float x = Mathf.Clamp(target.position.x, xMin, xMax);
19.         float y = Mathf.Clamp(target.position.y, yMin, yMax);
20.  
21.         t.position = new Vector3(x, y, t.position.z);
22.  
23.         Vector3 desiredPosition = t.position = target.position;
24.         Vector3 camPosition = Vector3.Lerp(t.position,desiredPosition,camSPD*Time.deltaTime);
25.      
26.         transform.position = camPosition;
27.      
28.     }
29. }

Any help is appreciated

Edit: Solved it

Code (CSharp):

1. using UnityEngine;
2.  
3. public class CameraFollow : MonoBehaviour {
4.     public Transform target;
5.  
6.     Vector3 velocity = Vector3.zero;
7.  
8.     public float camSpeed = 0.15f;
9.  
10.     public bool xMinEnabled = false;
11.     public float xMin = 0;
12.     public bool xMaxEnabled = false;
13.     public float xMax = 0;
14.     public bool yMinEnabled = false;
15.     public float yMin = 0;
16.     public bool yMaxEnabled = false;
17.     public float yMax = 0;
18.  
19.     void FixedUpdate () {
20.         Vector3 targetPos = target.position;
21.  
22.         // Horizontal Boundaries
23.         if (xMinEnabled && xMaxEnabled) {
24.             targetPos.x = Mathf.Clamp(target.position.x, xMin, xMax);
25.         } else if (xMinEnabled) {
26.             targetPos.x = Mathf.Clamp(target.position.x, xMin, target.position.x);
27.         } else if (xMaxEnabled) {
28.             targetPos.x = Mathf.Clamp(target.position.x, target.position.x, xMax);
29.         }
30.  
31.         // Vertical Boundaries
32.         if (yMinEnabled && yMaxEnabled) {
33.             targetPos.y = Mathf.Clamp(target.position.y, yMin, yMax);
34.         } else if (yMinEnabled) {
35.             targetPos.y = Mathf.Clamp(target.position.y, yMin, target.position.y);
36.         } else if (yMaxEnabled) {
37.             targetPos.y = Mathf.Clamp(target.position.y, target.position.y, yMax);
38.         }
39.  
40.         targetPos.z = transform.position.z;
41.         transform.position = Vector3.SmoothDamp(transform.position, targetPos, ref velocity, camSpeed);
42.     }
43. }
