Read file in Xcode project with Swift

Question

I made a method to read a file from the temporary folder. I use the following lines to get the document's path:

path = NSTemporaryDirectory().stringByAppendingPathComponent(folder)
path = path.stringByAppendingPathComponent(fileName + "." + fileType)

And it works great. My question is: how do I get the path for a file located in the main folders of the Xcode project? They are two text files that I drag and drop from a folder to the Xcode project. I selected the option "copy files if needed" when dropping the files. Thanks!

Answer 1

What you are looking for is app's main bundle. You get a path of a file in it like this:

if let path = NSBundle.mainBundle().pathForResource(fileName, ofType:fileType) {
    // use path
}

Keep in mind this folder is read-only so you will need to copy the files to temp or documents folders if you want to make changes.

Update the Swift 3.1 - Thanks @Filip Radelic

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