unable to delete file from the app documents folder

Using Swift 3, I'm writing a video file to the documents folder. here's the path of the file.

file:///var/mobile/Containers/Data/Application/D031AB20-CB7E-4B14-9483-E7C3F4C0EC55/Documents/output11:10:04.mov

now I want to delete the file again using the filemanager. I retrieve the path above from the avassetwriter and use the outputurl I defined earlier to remove the file using the filemanager.

let fileManager = FileManager.default

   do {
       try fileManager.removeItem(at: (self.assetWriter?.outputURL)!)
      } catch let err {
        print(err)
      }

but I get the error that there is no such file or directory. using self.assetWriter?.outputURL.pathgives me the same error.

Error Domain=NSCocoaErrorDomain Code=4 "“output11/10/04.mov” couldn’t be removed." UserInfo={NSFilePath=/var/mobile/Containers/Data/Application/D031AB20-CB7E-4B14-9483-E7C3F4C0EC55/Documents/output11:10:04.mov, NSUserStringVariant=( Remove ), NSUnderlyingError=0x174240150 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}

before deleting file , please check if file is exist at that path or not? As your error is showing that this file is not exists at location. – Saurabh Prajapati

Do not use colons in file names.

(For legacy reasons) the OS treats them as path separators and replaces them with slashes.

First Check weather the file exist at this path or not if exist then delete it :-

let file_manager = FileManager.init()
        if let url = self.assetWriter?.outputURL{
            if file_manager.fileExists(atPath: url.path){
                if file_manager.isDeletableFile(atPath: url.path){
                    do {
                        try file_manager.removeItem(at: url)
                    } catch let err {
                        print(err.localizedDescription)
                    }
                }
            }
        }

remove "file://" string from starting. 

 let path = documentPathValue.replacingOccurrences(of: "file://", with: "")

complete code

 func clearAllFilesFromDirectory() {

    let fileManager = FileManager.default
    let documentsUrl = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] as NSURL
    let documentsPath = documentsUrl.path

    do {
        if let documentPathValue = documentsPath{

            let path = documentPathValue.replacingOccurrences(of: "file://", with: "")
            let fileNames = try fileManager.contentsOfDirectory(atPath: "\(path)")
            print("all files in cache: \(fileNames)")

            for fileName in fileNames {

                let tempPath = String(format: "%@/%@", path, fileName)

                //Check for specific file which you don't want to delete. For me .sqlite files
                if !tempPath.contains(".sql") {
                    try fileManager.removeItem(atPath: tempPath)
                } 
            }
        }

    } catch {
        print("Could not clear document directory \(error)")
    }
}
