How to store files in folder which is created by using “documentDirectory” swift

I am creating new folder using createDirectory with below code.

    *let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
    // Get documents folder
    let documentsDirectory: String = paths.first ?? ""
    // Get your folder path
    let dataPath = documentsDirectory + "/MyNewFolder"
    print("Path\(dataPath)")
    if !FileManager.default.fileExists(atPath: dataPath) {
        // Creates that folder if no exists
        try? FileManager.default.createDirectory(atPath: dataPath, withIntermediateDirectories: false, attributes: nil)
    }*

Now i want to store new file like log.text under “MyNewFolder”. Can anybody suggest me how to save new files under “MyNewFolder” folder

Thanks in advance.

NSSearchPathForDirectoriesInDomains is outdated. The recommended API is the URL related API of FileManager

let folderName = "MyNewFolder"
let fileManager = FileManager.default
let documentsFolder = try! fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let folderURL = documentsFolder.appendingPathComponent(folderName)
let folderExists = (try? folderURL.checkResourceIsReachable()) ?? false
do {
    if !folderExists {
        try fileManager.createDirectory(at: folderURL, withIntermediateDirectories: false)
    }
    let fileURL = folderURL.appendingPathComponent("log.txt")
    let hello = Data("hello".utf8)
    try hello.write(to: fileURL)
    
} catch { print(error) }

You are strongly discouraged from building paths by concatenating strings.

Update:

In iOS 16+, macOS 13+ Apple moved the APIs to get the URLs of the standard folders into URL. appendingPathComponent has also been changed to be able to tell the compiler that the path represents a directory

let folderName = "MyNewFolder"
let folderURL = URL.documentsDirectory.appending(path: folderName, directoryHint: .isDirectory)
let folderExists = (try? folderURL.checkResourceIsReachable()) ?? false
do {
    if !folderExists {
        try fileManager.createDirectory(at: folderURL, withIntermediateDirectories: false)
    }
    let fileURL = folderURL.appendingPathComponent("log.txt")
    let hello = Data("hello".utf8)
    try hello.write(to: fileURL)
    
} catch { print(error) }

You can try

try? FileManager.default.createDirectory(atPath: dataPath, withIntermediateDirectories: false, attributes: nil)

do { 

    let sto =  URL(fileURLWithPath: dataPath + "log.txt")  // or let sto =  URL(fileURLWithPath: dataPath + "/log.txt") 

    try Data("SomeValue".utf8).write(to: sto)

    let read = try Data(contentsOf: sto)

    print(String(data: read, encoding: .utf8)!)
}
catch {

    print(error)
}

let filePath = dataPath + "/log.txt"
FileManager.default.createFile(filePath, contents:dataWithFileContents, attributes:nil)
