You&#39;re implementing a method from the protocol, yes, but it&#39;s not an override. Just remove the `override` keyword. An override is when your superclass also implements that method and you&#39;re providing a version that replaces or modifies the behavior of the superclass implementation. That&#39;s not what&#39;s happening here.

Situation:

Open a text file in n++, make some modification, press ALT-F4 or Close program.
The N++ won&#39;t ask &quot;Do you want to save your changes&quot;. Instead it quits and text file on hdd remains unchanged.

But when I open the N++ again, the MODIFIED file is still in there. Red tab is indicating unsaved changes and I can save it by ctrl-s. I can also save it by closing the tab (n++ will ask).

I want to save the file automatically every time I close the n++. All of my other istallations does that but this. I could not find any settings in the n++ options. Any idea?

I need to set the file descriptor limit correctly on the docker container 
I connect to container with ssh (https://github.com/phusion/baseimage-docker)

Already tried:

- edit limits.conf  the container ignore this file 
- upstart procedure found at https://coderwall.com/p/myodcq but this docker image has different kind of init process. (runit)
- I tried to modify configuration of pam library in /etc/pam.d
- try to enabled pam for ssh  in sshd_config

The output it always the same. 

    bash: ulimit: open files: cannot modify limit: Operation not permitted

Since Xcode 6 still has a lots of bugs with Swift, I&#39;m not sure is it one or I&#39;m missing something.
My class adopts protocol NSLayoutManagerDelegate. But it seems impossible to override method I need. I do as documentation describes:

    override func layoutManager(_ aLayoutManager: NSLayoutManager!,
    		didCompleteLayoutForTextContainer aTextContainer: NSTextContainer!,
    		atEnd flag: Bool) {
    			
    	}

But I get error here: method does not override any method from its superclass.
What should I do?

My cocoa app has to change its behaviour when run in the new OS X &quot;dark mode&quot;.

Is there a way to detect if OS X style is set to this mode?

I&#39;m quite new to programming a Swift and I&#39;m trying to iterate through the files in a folder.
I took a look at the answer [here][1] and tried to translate it to Swift syntax, but didn&#39;t succeed.

    let fileManager = NSFileManager.defaultManager()
    let enumerator:NSDirectoryEnumerator = fileManager.enumeratorAtPath(folderPath)
    
    for element in enumerator {
        //do something
    }

the error I get is:

    Type &#39;NSDirectoryEnumerator&#39; does not conform to protocol &#39;SequenceType&#39;

My aim is to look at all the subfolders and files contained into the main folder and find all the files with a certain extension to then do something with them.

I understand that the following command will update a single pod: `pod update &lt;podname&gt;`. However this also updates the dependencies of other pods (pods that were not included in the update command) that you have previously installed. Is there a way to update a single pod and leave all other dependencies alone?

How do I get the application name in Swift?

Googling gave me this:

    [[[NSBundle mainBundle] infoDictionary] objectForKey:@&quot;CFBundleName&quot;];

I converted it to Swift; error - method doesn&#39;t exist:

    NSBundle.mainBundle().infoDictionary.objectForKey(&quot;CFBundleName&quot;)

I&#39;ve been trying to achieve the goal of having a unique (not shared) cookie jar per WebView in macOS (cookies management works different for iOS).

After reading a lot of StackOverflow questions and digging through the docs, I found the closest solution to my problem in these articles:

* ([how to handle HTTP cookies][1])
* ([how to handle JavaScript document.cookie cookies][2])

I have set up an example app using them: https://github.com/jjconti/swift-webview-isolated

The basic idea is to implement the necessary methods from the WebResourceLoadDelegate and WebPolicyDelegate protocols and use BSHTTPCookieStorage to store and retrieve cookies. Additionally, my example app allows saving the cookieStorage object so it can be reloaded in future executions.

Unfortunately, the app doesn&#39;t work correctly in every website (the author of the articles was targeting one particular web site). For example Gmail and NewRelic, you&#39;re immediately logged out after login (or after doing some actions). That makes me suspect a bug in the cookie storage implementation which I haven&#39;t been able to find yet.

Could someone tell me if there&#39;s something I&#39;m missing?

I have &quot;UserDetails&quot; struct objects in array..I want to filter the objects from array. But there is no option for &quot;filteredArrayUsingPredicate&quot; in Swift array.

My array creation

    var arrayOfUsers:UserDetails[] = UserDetails[]()

my userdetails code is 

    struct UserDetails{
        var userName:String
        var userID:String
        var userAge:String
        func userDescription()-&gt;String{
            return &quot;name &quot; + userName + &quot;age &quot; + userID
        }
    }


my code to create objects 

            for a in 1...1000{
                var user:UserDetails = UserDetails(userName: &quot;name&quot;, userID: String(a), userAge: &quot;22&quot;)
                arrayOfUsers.append(user)
            }

Now I want to filter `arrayOfUsers` which one has userID &quot;1&quot;.

I&#39;m trying to play a sound with `AVAudioPlayer` but it won&#39;t work.

**Edit 1:** Still doesn&#39;t work.

**Edit 2**: This code works. My device was in silent mode.
    
    import UIKit
    import AVFoundation

    class ViewController: UIViewController {
    
        var audioPlayer = AVAudioPlayer()
                            
        override func viewDidLoad() {
            super.viewDidLoad()
        
            var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(&quot;button-09&quot;, ofType: &quot;wav&quot;))
            println(alertSound)
        
            var error:NSError?
            audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &amp;error)
            audioPlayer.prepareToPlay()
            audioPlayer.play()
        }
    }

In Swift, I am trying to create an array of 64 SKSpriteNode. I want first to initialize it empty, then I would put Sprites in the first 16 cells, and the last 16 cells (simulating an chess game).

From what I understood in the doc, I would have expect something like:

&lt;code&gt;var sprites = SKSpriteNode()[64];&lt;/code&gt;

or

&lt;code&gt;var sprites4 : SKSpriteNode[64];&lt;/code&gt;

But it doesn&#39;t work. 
In the second case, I get an error saying: &quot;Fixed-length arrays are not yet supported&quot;. Can that be real? To me that sounds like a basic feature.
I need to access the element directly by their index.

I&#39;m trying to declare an argument in Swift that takes an optional closure. The function I have declared looks like this:

    class Promise {
     
     func then(onFulfilled: ()-&gt;(), onReject: ()-&gt;()?){       
        if let callableRjector = onReject {
          // do stuff! 
        }
     }

    }
 
But Swift complains that &quot;Bound value in a conditional must be an Optional type&quot; where the &quot;if let&quot; is declared. 


How does one make an optional closure in swift?

How would I go about changing the color of the `UINavigationBar` in Swift?

Most things online say to do something like:

    [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];


Which I translated to 

    let titleDict: NSDictionary = [&quot;NSForegroundColorAttributeName&quot;: UIColor.whiteColor()]
    self.navigationController.navigationBartitleTextAttributes = titleDict
    //self is referring to a UIViewController

But it doesn&#39;t work.  I already changed the background and button colors, but the text color doesn&#39;t change.  Any ideas?
