How to get user home directory path (Users/"user name") without knowing the username in Swift3

I am making a func that edits a text file in the Users/johnDoe Dir. 

let filename = "random.txt"
let filePath = "/Users/johnDoe"
let replacementText = "random bits of text"
do {

 try replacementText.write(toFile: filePath, atomically: true, encoding: .utf8)

}catch let error as NSError {
print(error: + error.localizedDescription)
}

But I want to be able to have the path universal. Something like 

let fileManager = FileManager.default
    let downloadsURL =  FileManager.default.urls(for: .downloadsDirectory, in: .userDomainMask).first! as NSURL
    let downloadsPath = downloadsURL.path

but for the JohnDoe folder. I haven't been able to find any documentation on how to do this. The closest thing I could find mentioned using NSHomeDirectory(). And I am not sure how to use it in this context.

when I try adding it like...

let fileManager = FileManager.default
    let downloadsURL =  FileManager.default.urls(for: NSHomeDirectory, in: .userDomainMask).first! as NSURL
    let downloadsPath = downloadsURL.path

I get an error:

"Cannot Convert value of type 'String' to expected argument type 'FileManager.SearchPathDirectory'"

I've tried it .NSHomeDirectory, .NSHomeDirectory(), NShomeDirectory, NShomeDirectory()

Solution

  • You can use FileManager property homeDirectoryForCurrentUser

    let homeDirURL = FileManager.default.homeDirectoryForCurrentUser

    If you need it to work with earlier OS versions than 10.12 you can use

    let homeDirURL = URL(fileURLWithPath: NSHomeDirectory())

    print(homeDirURL.path)
