Cannot write Data to file in Swift - swift

Question

I have an image that I want it's data to be saved in this fileUri generated by ("react-native-fs"). LibraryDirectoryPath/saved_images/{filename}:
/Users/macbookpro/Library/Developer/CoreSimulator/Devices/9CBD2F1E-7330-418D-81BE-108C064DEA7E/data/Containers/Data/Application/C26348CC-3463-43EF-9B26-B7E31641E2EA/Library/saved_images/6B3A6A3A-8DE3-488B-AF43-A54775545B38.jpg
And below is my implementation:
do {
let url = URL(string: fileUri)
let fileExisted = FileManager().fileExists(atPath: url!.path)
if (fileExisted) {
try decryptedData.write(to: url!)
} else {
let handle = try FileHandle(forWritingTo: url!)
handle.write(data) // data is type Data
handle.closeFile()
}
} catch {
reject("FileError", "Failed to write file", error)
}
I also tried let url = URL(fileURLWithPath: fileUri) with and without file:// prepending to fileUri
do {
let url = URL(fileURLWithPath: fileUri)
let fileExisted = FileManager().fileExists(atPath: url.path)
if (fileExisted) {
try decryptedData.write(to: url)
} else {
let handle = try FileHandle(forWritingTo: url)
handle.write(data)
handle.closeFile()
}
} catch {
reject("FileError", "Failed to write file " + error.localizedDescription, error)
}
it says:

You are using the wrong API.
let url = URL(string: fileUri)
is for strings representing a full – even encoded - URL starting with a scheme like file:// or https://.
On the other hand fileUri is actually a path without a scheme, so you have to use
let url = URL(fileURLWithPath: fileUri)
This returns a non optional URL by adding the file:// scheme.
fileUri should be renamed as filePath.
