UPDATE
I tried the following code solution and it allows for me to save to Google Drive now, but Egnyte and Dropbox are still greyed out.
func exportPhotosToFileLocation() {
var fileURLArray = [URL]()
for data in reviewDataController.tableViewReviewData {
guard let imageData = data.image.jpegData(compressionQuality: 1.00) else {
print("ERROR: Unable to print convert image to jpegData in exportPhotosToFileLocation!")
return
}
let fileManager = FileManager.default
do {
let fileURL = fileManager.temporaryDirectory.appendingPathComponent("(data.imageTitle)").appendingPathExtension("jpeg")
try imageData.write(to: fileURL)
fileURLArray.append(fileURL)
print("Successfully created file from jpegData in exportPhotosToFileLocation!")
} catch {
print("ERROR: Unable to create file from jpegData in exportPhotosToFileLocation!")
return
}
}
if #available(iOS 14, *) {
let controller = UIDocumentPickerViewController(forExporting: fileURLArray)
present(controller, animated: true)
}
else {
let controller = UIDocumentPickerViewController(urls: fileURLArray, in: .exportToService)
present(controller, animated: true)
}
}
Here is the developer documents for Egnyte. Unfortunately, none of it makes sense to me as a beginner.

ORIGINAL POST
In my app, I’m trying to allow the user to select a save location (so choose a folder). Whenever I use this code, Egnyte/Google Drive/Dropbox are all "greyed" out and inaccessible.
let supportedTypes : [UTType] = [UTType.folder]
let documentPickerController = UIDocumentPickerViewController(forOpeningContentTypes: supportedTypes)
documentPickerController.delegate = self
self.present(documentPickerController, animated: true, completion: nil)
If I change supportedTypes to
let supportedTypes : [UTType] = [UTType.text]
It does let me access them. Does anyone have a solution for this? I obviously need the user to be able to select a folder in these applications… you can see why that is important.

This is up to the file provider extension (Google Drive, etc.). To allow picking a folder, the file provider has to lay content in its directory in a hierarchical manner… if they do this, they need to specify NSExtensionFileProviderSupportsPickingFolders in their Info.plist to tell the system it’s allowed to choose folders.
Do you need to choose a save location and persist it? If yes, then you’ll be blocked on the file provider implementing the necessary API. If not, the type you pass should the type of the document you are actually saving. The document will be saved once in the chosen folder (without any additional requirements on the file provider extension), and you will have to use the document picker again to save the next document.
If you are trying to select Dropbox as a location to import files from in the Apple File Importer but it does not advance to the file selection screen I found that restarting my iPhone seemed to resolve that issue.
