The below code worked for me.
Button {
if post.post_type != PostType.mp4.rawValue {
let imagedData = NSData(contentsOf: imageURL)!
InstagramManager.instance.postImage(image: UIImage(data: imagedData as Data)!) { success in
print("insgram shared success = \(success)")
}
} else {
let videoData = NSData(contentsOf: videoUrl!)
InstagramManager.instance.postVideoToInstagramFeed(videoData: videoData!)
}
import SwiftUI
import Photos
final class InstagramManager : NSObject {
public static let instance = InstagramManager()
func postImage(image: UIImage, result:((Bool)->Void)? = nil) {
guard let instagramURL = NSURL(string: "instagram://app") else {
if let result = result {
result(false)
}
return
}
// let image = image.scaleImageWithAspectToWidth(640)
do {
try PHPhotoLibrary.shared().performChangesAndWait {
let request = PHAssetChangeRequest.creationRequestForAsset(from: image)
let assetID = request.placeholderForCreatedAsset?.localIdentifier ?? ""
let shareURL = "instagram://library?LocalIdentifier=" + assetID
if UIApplication.shared.canOpenURL(instagramURL as URL) {
if let urlForRedirect = NSURL(string: shareURL) {
UIApplication.shared.open(URL(string: "\(urlForRedirect)")!)
}
}
}
} catch {
if let result = result {
result(false)
}
}
}
func postVideoToInstagramFeed(videoData: NSData) {
getLibraryPermissionIfNecessary { granted in
guard granted else { return }
}
PHPhotoLibrary.shared().performChanges({
let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0];
let filePath = "\(documentsPath)/\(Date().description).mp4"
videoData.write(toFile: filePath, atomically: true)
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: URL(fileURLWithPath: filePath))
},
completionHandler: { success, error in
if success {
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "modificationDate", ascending: false)]
let fetchResult = PHAsset.fetchAssets(with: .video, options: fetchOptions)
if let lastAsset = fetchResult.firstObject {
let localIdentifier = lastAsset.localIdentifier
let urlFeed = "instagram://library?LocalIdentifier=" + localIdentifier
guard
let url = URL(string: urlFeed)
else {
print("Could not open url")
return
}
DispatchQueue.main.async {
if UIApplication.shared.canOpenURL(url) {
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: { (success) in
print("Sucess")
})
}
else {
UIApplication.shared.openURL(url)

}
}
else {
print("Instagram not found")
}
}
}
}
else if let error = error {
print(error.localizedDescription)
}
else {
print("Could not save the video")
}
})
}
func getLibraryPermissionIfNecessary(completionHandler: #escaping (Bool) -> Void) {
guard PHPhotoLibrary.authorizationStatus() != .authorized else {
completionHandler(true)
return
}
PHPhotoLibrary.requestAuthorization { status in
completionHandler(status == .authorized)
}
}
}
