Swift 3 : How to get path of file saved in Documents folder

Question

path = Bundle.main.path(forResource: "Owl.jpg", ofType: "jpg")

returns nil, however, using NSHomeDirectory() I'm able to verify that is under Documents/ folder.

Answer 1

First, separate name and extension:

Bundle.main.path(forResource: "Owl", ofType: "jpg")

Second, separate (mentally) your bundle and the Documents folder. They are two completely different things. If this file is the Documents folder, it absolutely is not in your main bundle! You probably want something like this:

let fm = FileManager.default
let docsurl = try! fm.url(for:.documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let myurl = docsurl.appendingPathComponent("Owl.jpg")

Third, if Owl is an image asset in the asset catalog, then say

let im = UIImage(named:"Owl") // or whatever its name is

Answer 2

Tested on: xCode 8.3.2 & Swift 3.1

First drag your file (JPG, MP3, ZIP) inside your project folder and make sure Copy items if needed is checked and project/app is selected in Add to targets

Inside relevant ViewController

let fileName = "fileName"
let fileType = "fileType"

if let filePath = Bundle.main.path(forResource: fileName, ofType: fileType) {
    print(filePath)
}

If you need to get the file URL you can use NSBundle method

if let fileURL = Bundle.main.url(forResource: fileName, withExtension: fileType) {
    print(fileURL)
}

Also NSBundle method pathForResource has an initializer that you can specify in which directory your files are located like:

if let filePath = Bundle.main.path(forResource: fileName, ofType: fileType, inDirectory: "filesSubDirectory") {
    print(filePath)
}

And for getting file URL:

if let fileURL = Bundle.main.url(forResource: fileName, withExtension: fileType, subdirectory: "filesSubDirectory") {
    print(fileURL)
}
