Swift 2.0 : NSBundle always returns nil

Question

I'm implementing this git - NSDate-TimeAgo

It has swift extension inside. I have dragged and drop the Bundle that the git supply into my app - NSDateTimeAgo.bundle

In the extension file im trying to get this file path , but it always return nil SWIFT 2.0

func NSDateTimeAgoLocalizedStrings(key: String) -> String {

let resourcePath = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
let path = resourcePath.URLByAppendingPathComponent("NSDateTimeAgo.bundle")
let bundle = NSBundle(URL: path)
print(bundle) -> **nil**

return NSLocalizedString(key, tableName: "NSDateTimeAgo", bundle: bundle!, comment: "")
}

Any suggestions?

Does the bundle exist in the app's document folder? – trojanfoe Sep 23 '15 at 19:12 — trojanfoe, Sep 23 '15 at 19:12

The bundle has to be copied into your resources folder, not into the top level of your app bundle.

This line is just wrong:

let resourcePath = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]

The bundle is not in your documents directory. It's in your app. Look at what the actual code does (in NSDate+Extension.swift):

func NSDateTimeAgoLocalizedStrings(key: String) -> String {

    // LOOK!!!!
    let resourcePath = NSBundle.mainBundle().resourcePath
    let path = resourcePath?.stringByAppendingPathComponent("NSDateTimeAgo.bundle")
    let bundle = NSBundle(path: path!)

    return NSLocalizedString(key, tableName: "NSDateTimeAgo", bundle: bundle!, comment: "")
}

Basically you should just let it do this. Don't mess with the bundle yourself. Just install NSDate+Extension.swift and the bundle, and stop. Don't change the code - all you're doing is breaking it.

Matt , im using swift 2.0 - stringByAppendingPathComponent - is available . Any chance you can modify the code above? — Roi Mulia, Sep 26 '15 at 16:21

In case the accepted haven't worked - found solution -

  guard let resourcePath = NSBundle.mainBundle().resourcePath else {
        return ""
    }

    let path = NSURL(fileURLWithPath:resourcePath).URLByAppendingPathComponent("NSDateTimeAgo.bundle")
    guard let bundle = NSBundle(URL: path) else {
        return ""
    }

    return NSLocalizedString(key, tableName: "NSDateTimeAgo", bundle: bundle, comment: "")
