Delete specified file from document directory

I checked your code. It's working for me. Check any error you are getting using the modified code below

- (void)removeImage:(NSString *)filename{  NSFileManager *fileManager = [NSFileManager defaultManager];  NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];  NSString *filePath = [documentsPath stringByAppendingPathComponent:filename];  NSError *error;  BOOL success = [fileManager removeItemAtPath:filePath error:&error];  if (success) {      UIAlertView *removedSuccessFullyAlert = [[UIAlertView alloc] initWithTitle:@"Congratulations:" message:@"Successfully removed" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];      [removedSuccessFullyAlert show];  }  else  {      NSLog(@"Could not delete file -:%@ ",[error localizedDescription]);  }}

Swift 3.0:

func removeImage(itemName:String, fileExtension: String) {  let fileManager = FileManager.default  let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory  let nsUserDomainMask = FileManager.SearchPathDomainMask.userDomainMask  let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)  guard let dirPath = paths.first else {      return  }    let filePath = "\(dirPath)/\(itemName).\(fileExtension)"  do {    try fileManager.removeItem(atPath: filePath)  } catch let error as NSError {    print(error.debugDescription)  }}

Thanks to @Anil Varghese, I wrote very similiar code in swift 2.0:

static func removeImage(itemName:String, fileExtension: String) {  let fileManager = NSFileManager.defaultManager()  let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory  let nsUserDomainMask = NSSearchPathDomainMask.UserDomainMask  let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)  guard let dirPath = paths.first else {    return  }  let filePath = "\(dirPath)/\(itemName).\(fileExtension)"  do {    try fileManager.removeItemAtPath(filePath)  } catch let error as NSError {    print(error.debugDescription)  }}

Swift 2.0:

func removeOldFileIfExist() {    let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)    if paths.count > 0 {        let dirPath = paths[0]        let fileName = "someFileName"        let filePath = NSString(format:"%@/%@.png", dirPath, fileName) as String        if NSFileManager.defaultManager().fileExistsAtPath(filePath) {            do {                try NSFileManager.defaultManager().removeItemAtPath(filePath)                print("old image has been removed")            } catch {                print("an error during a removing")            }        }    }}
