Save-To-iCloud-Drive

Save a document to iCloud drive

Steps to follow:

1. Start new Project

2. Enable iCloud Documents with Xcode, from tab Capabilities

3. Create App Id and enable iCloud feature to your App Id

4. Go to Info.plist of you application and add something similar to this.

   Note: You need to have NSUbiquitousContainerIsDocumentScopePublic=true in Info.plist before you run the app for the first time, Otherwise directory will not be shown in iCloud Drive, It will be a hidden directory.

   <key>NSUbiquitousContainers</key>
   <dict>
   	<key>iCloud.$(PRODUCT_BUNDLE_IDENTIFIER)</key>
   	<dict>
   		<key>NSUbiquitousContainerIsDocumentScopePublic</key>
   		<true/>
   		<key>NSUbiquitousContainerName</key>
   		<string>Folder_Name</string>
   		<key>NSUbiquitousContainerSupportedFolderLevels</key>
   		<string>Any</string>
   	</dict>
   </dict>

5. In ViewController Create Directory

   func createDirectory(){
       if let iCloudDocumentsURL = FileManager.default.url(forUbiquityContainerIdentifier: nil)?.appendingPathComponent("Documents") {
           if (!FileManager.default.fileExists(atPath: iCloudDocumentsURL.path, isDirectory: nil)) {
               do {
                   try FileManager.default.createDirectory(at: iCloudDocumentsURL, withIntermediateDirectories: true, attributes: nil)
               }
               catch {
                   //Error handling
                   print("Error in creating doc")
               }
           }
       }
   }

6. Then put all files inside to this Directory

   func copyDocumentsToiCloudDirectory() {
       guard let localDocumentsURL = FileManager.default.urls(for: FileManager.SearchPathDirectory.documentDirectory, in: .userDomainMask).last else { return }
       
       guard let iCloudDocumentsURL = FileManager.default.url(forUbiquityContainerIdentifier: nil)?.appendingPathComponent("Documents").appendingPathComponent("Subdirectory") else { return }
       
       var isDir:ObjCBool = false
       
       if FileManager.default.fileExists(atPath: iCloudDocumentsURL.path, isDirectory: &isDir) {
           do {
               try FileManager.default.removeItem(at: iCloudDocumentsURL)
           }
           catch {
               //Error handling
               print("Error in remove item")
           }
       }
       
       do {
           try FileManager.default.copyItem(at: localDocumentsURL, to: iCloudDocumentsURL)
       }
       catch {
           //Error handling
           print("Error in copy item")
       }
   }

   7: Run the application
