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

Question

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 1

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)

Solution 2

There should be an easier way but -- at worst -- this should work:

let filePath = NSString(string: "~").expandingTildeInPath

Yeah it works but only for 10.12+ I need it to work with 10.9 Up I should have mentioned that in my post sorry

You sir... I could kiss you write now =). very simple and works like a charm. I guess I was trying to over think it.

This doesn't add anything that isn't already in the accepted answer

This will return app's home folder instead of user's if sandbox

This Answer is just for macOS, do we have home dir or something like that for iOS as well?

@ioscoder There is no home folder for iOS. What you have is the documents directory

@ioscoder for more info about which folder to use you should take some time and read File System Basics. If you would like to get a specific folder in your app check this post Getting list of files in documents folder
