Where can a sandboxed Mac app save files?

My Mac app is sandboxed and I need to save a file. Where do I save this file? I can't seem to find the specific place where this is allowed without using an open panel. This is how I do it on iOS:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [paths objectAtIndex:0];

What is the equivalent for the sandboxed directory on Mac?

Converting @Mazyod's answer into Swift (5.1):

var appPath: URL? {
    //Create App directory if not exists:
    let fileManager = FileManager()
    let urlPaths = fileManager.urls(for: .applicationSupportDirectory, in: .userDomainMask)
    if let bundleID = Bundle.main.bundleIdentifier, let appDirectory = urlPaths.first?.appendingPathComponent(bundleID,isDirectory: true) {
        var objCTrue: ObjCBool = true
        let path = appDirectory.path
        if !fileManager.fileExists(atPath: path,isDirectory: &objCTrue) {
            do {
                try fileManager.createDirectory(atPath: path, withIntermediateDirectories: true, attributes: nil)
            } catch {
                return nil
            }
        }
        return appDirectory
    }
    return nil
}

However, the directory has changed and I am not sure that the additonal repetition of the bundle ID is needed as the path is 

"/Users/**user name**/Library/Containers/**bundleID**/Data/Library/Application Support/**bundleID**".

But it seems to work.

Is is even easier. For sandboxed apps on macOS the function NSHomeDirectory gives you the path where you have read and write access and can save all your files. It will be a path like this

/Users/username/Library/Containers/com.yourcompany.YourApp
