Getting the url of a video (PHAsset) for video uploading - swift - ios

Question

I've created two different functions for uploading PHASSets to my backend -
the uploadImageAsset() uploads all of the assets that are images:
func uploadImageAsset(asset: PHAsset, projectRef: String) {
let userID = Auth.auth().currentUser?.uid
let db = Firestore.firestore()
let dbRef = db.collection("projects").document(projectRef)
let manager = PHImageManager.default()
let option = PHImageRequestOptions()
option.isSynchronous = false
option.isNetworkAccessAllowed = true
option.resizeMode = .exact
option.version = .original
option.deliveryMode = .highQualityFormat
let imageSize = CGSize(width: asset.pixelWidth, height: asset.pixelHeight)
let uniqueImageID = NSUUID().uuidString
let storageRef = Storage.storage().reference().child("project-images").child("\(uniqueImageID).jpeg")
manager.requestImage(for: asset, targetSize: imageSize, contentMode: .aspectFill, options: option) { (image, info) in
let uploadData = image?.jpegData(compressionQuality: 0.6)
storageRef.putData(uploadData!, metadata: nil, completion: {
(metadata, error) in
if error != nil {
return
} else {
storageRef.getMetadata(completion: { (metadata, err) in
if let error = err {
print(error)
} else {
storageRef.downloadURL(completion: { (url, err) in
if let error = err {
print(error)
} else {
self.imageURLs.append((url?.absoluteString)!)
dbRef.updateData(["image": self.imageURLs], completion: { (err) in
if err != nil {
print(err)
} else {
SVProgressHUD.dismiss(withDelay: 0.3)
self.dismiss(animated: true, completion: nil)
}
})
}
})
}
})
}
})
}
}
and the uploadProjectVideos() uploads all of the assets that are videos:
func uploadVideoAsset(asset: PHAsset, projectRef: String) {
let userID = Auth.auth().currentUser?.uid
let db = Firestore.firestore()
let dbRef = db.collection("projects").document(projectRef)
let manager = PHImageManager.default()
let option = PHVideoRequestOptions()
option.isNetworkAccessAllowed = true
option.deliveryMode = PHVideoRequestOptionsDeliveryMode.highQualityFormat
manager.requestAVAsset(forVideo: asset, options: option) { (video, videoAudio, nil) in
let avurlAsset = video as! AVURLAsset
let fileURL = avurlAsset.url.absoluteString as! URL
let fileName = NSUUID().uuidString + ".mov"
let uploadTask = Storage.storage().reference().child(fileName).putFile(from: fileURL, metadata: nil, completion: { (metaData, error) in
if error != nil {
print("Failed upload of video", error)
return
}
Storage.storage().reference().child(fileName).downloadURL { (url, error) in
self.imageURLs.append("\(url)")
dbRef.updateData(["image": self.imageURLs], completion: { (err) in
if err != nil {
print(err)
} else {
SVProgressHUD.dismiss(withDelay: 0.3)
self.dismiss(animated: true, completion: nil)
}
})
}
})
}
}
When it comes to uploading images, my function for that works perfectly. However, my function for uploading videos is returning nil. Videos aren't being uploaded to the backend at all.
This is my first time working with PHAssets and Im really confused as to how I can get the video url of a phasset and upload it

You can use the requestAVAsset(forVideo:options:resultHandler:) method as shown in the documentation: https://developer.apple.com/documentation/photokit/phimagemanager/1616935-requestavasset.
And here's a little handy extension originally made by #iMHitesh Surani, updated to swift by #diegomen:
extension PHAsset {
func getURL(completionHandler : #escaping ((_ responseURL : URL?) -> Void)){
if self.mediaType == .image {
let options: PHContentEditingInputRequestOptions = PHContentEditingInputRequestOptions()
options.canHandleAdjustmentData = {(adjustmeta: PHAdjustmentData) -> Bool in
return true
}
self.requestContentEditingInput(with: options, completionHandler: {(contentEditingInput: PHContentEditingInput?, info: [AnyHashable : Any]) -> Void in
completionHandler(contentEditingInput!.fullSizeImageURL as URL?)
})
} else if self.mediaType == .video {
let options: PHVideoRequestOptions = PHVideoRequestOptions()
options.version = .original
PHImageManager.default().requestAVAsset(forVideo: self, options: options, resultHandler: {(asset: AVAsset?, audioMix: AVAudioMix?, info: [AnyHashable : Any]?) -> Void in
if let urlAsset = asset as? AVURLAsset {
let localVideoUrl: URL = urlAsset.url as URL
completionHandler(localVideoUrl)
} else {
completionHandler(nil)
}
})
}
}
}
