Answer 1

import MobileCoreServices for swift
@import MobileCoreServices; for objective c

Answer 2

You have to add the framework MobileCoreServices to the project, and then import it:

Objective C:

#import <MobileCoreServices/MobileCoreServices.h>

That will make the problem go away.

Swift 4:

import MobileCoreServices

Answer 3

I am a novice at iOS development and xcode and spent some time trying to find out why just the import was not working. After figuring out the problem with a more experienced member of my team I found out that not only must you include

#import <MobileCoreServices/MobileCoreServices.h>

but you must also link binaries to the library of the MobileCoreServices framework to the build phases of your project.

Hope this helps! I sure needed this info when I was doing this.

Answer 4

swift

import MobileCoreServices

objective c

#import <MobileCoreServices/MobileCoreServices.h>

Answer 5

Swift 4 answer, with video camera code and imagePicker delegate:

import MobileCoreServices

Open Video Camera

   @IBAction func openVideoCamera(_ sender: Any) {
     if UIImagePickerController.isSourceTypeAvailable(.camera) {
        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = .camera
        imagePicker.mediaTypes = [kUTTypeMovie as String]
        imagePicker.videoMaximumDuration = 10 // or whatever you want
        imagePicker.videoQuality = .typeMedium
        imagePicker.allowsEditing = false
        present(imagePicker, animated: true, completion: nil)
    }

ImagePicker delegate:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let mediaType = info[UIImagePickerControllerMediaType] as AnyObject

    if mediaType as! String == kUTTypeMovie as String {
            let videoURL = info[UIImagePickerControllerMediaURL] as? URL
            print("VIDEO URL: \(videoURL!)")
    }
    dismiss(animated: true, completion: nil)
}

Answer 6

1. Add MobileCoreServices.framework if not added already. Select your target and add linked binaries with library.
2. Add #import <MobileCoreServices/MobileCoreServices.h>
