SearchPathDirectory.documentDirectory, FileManager. SearchPathDomainMask.allDomainsMask, true) if dirs.count > 0 { let dir = dirs[0] //documents directory filePath = dir.appending("/" + fileName) print("Local path = \(filePath)") } else { print("Could not find local directory to store file") return } // Read file content. Example in Swift do { // Read file content let contentFromFile = try NSString(contentsOfFile: filePath, encoding: String.Encoding.utf8.rawValue) print(contentFromFile) } catch let error as NSError { print("An error took place: \(error)") } |
