title: Xcode 7 Creating correct App Icon Images
body: <p>So Ive raised a topic on this before because its something that has created a lot of confusion for me, and I'm sure it has for a lot of other users. Currently I have my Xcode project and my assets manager as comes supplied with every project created. by default an AppIcon already exists in here which looks a little like so...</p>
  
  <p><a href="https://i.stack.imgur.com/UpR33.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UpR33.png" alt="1st app icon image"></a></p>
  
  <p>You can see that this (the default) AppIcon has 3 types of icon that have to be loaded in. Currently I have 3 images:</p>
  
  <p>a 87x87@3x</p>
  
  <p>a 120x120@3x</p>
  
  <p>and a 180x180@3x. </p>
  
  <p>I have no idea what the extension means (the @3x bit) so it would be nice if someone wouldn't mind explaining that to me aswell. But back to the main problem I'm having...</p>
  
  <p>I find that when I go to create a new AppIcon, although its not necessary as I could just replace the images in the old AppIcon that is created by default, it does have a different interface which looks as follows:</p>
  
  <p><a href="https://i.stack.imgur.com/ljnjU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ljnjU.png" alt="new app icon interface"></a></p>
  
  <p>Now you should be able to see that the the "slots" in the new AppIcon are empty because I have absolutely no idea about what dimension images I am supposed to be supplying and to where they are supposed to go to within here. I also have no idea what extensions my images are supposed to be using and how many I am supposed to have. The whole process seems quite overwhelming and ridiculously complicated. I'm utterly confused as to why apple have made this so inefficient and just plain confusing :/</p>
  
  <p>I have been looking at an icon generator which seems rather useful (as recommended in my last thread):

  <p>and I have also had a look at this although it doesn't seem particularly helpful:

  <p>I have mainly been looking at this however it doesn't seem to offer much help if I'm honest:

  <p><strong><em>So to sum things up...</em></strong></p>
  
  <ol>
  <li>What resolution images do I need for app icons?</li>
  <li>Which AppIcon template am I using, the default or a newly created?</li>
  <li>What extensions do my images need? ("@2x", "@3x" etc.)</li>
  <li>What do the extensions mean/do?</li>
  </ol>
  
  <p><strong>Thanks anyways!</strong></p>

  <p><strong><em>UPDATE 1!</em></strong></p>
  
  <p>I have kindly been provided a great link for a app icon generator which works online, it seems very quick and very reliable and anyone having the same issues, I would recommend you give this a try :)
