MBProgressHUD not working in swift: cannot import and use

Junchao Gu picture Junchao Gu · Jun 10, 2015 · Viewed 7.4k times · Source

I used cocoapods to install MBProgressHUB and in bridging header I cannot just do

 #import "MBProgressHUD.h"

I changed to

#import "MBProgressHUD/MBProgressHUD.h"

the import is OK but I cannot use it in swift code? anything I do wrong? how can I solve this problem?

Try this:

1) Specify use_frameworks! in your Podfile to use frameworks (instead of static libraries).

This is required for adding pods that are written in Swift as dependencies and a good idea in general if your app is written in Swift.

2) Do pod install

This makes sure your project is setup to actually use the above.

3) Add #import <MBProgressHUD/MBProgressHUD.h> in your bridging header (notice the angle brackets- not quotes) and import MBProgressHUD in the Swift class that needs to use it.

That is,

MyApp-Bridging-Header.h :

#import <MBProgressHUD/MBProgressHUD.h>
// ... other imports ...

This exposes the Objective-C files to Swift. Angle brackets indicate this is actually importing a framework.

MyViewController.swift :

import UIKit
import MBProgressHUD
// ... other imports...

class MyViewController: UIViewController {
  // ... yada yada...
}

This actually imports the dependency for use by your view controller.
