App Icon has Unassigned Image error

Question

I'm getting these errors:

enter image description here

I can't tell exactly which thing it is talking about?

enter image description here

If it is a 42 mm 2x, then I don't have a spot to put that. Can you help? Thanks!

enter image description here

EDIT: Per comment below, I looked on the right pane. Looks like it needs the 44 2x...

enter image description here

...so I have one created, but the Unassigned doesn't highlight when I drag the icon over it, so how do I assign it in my image assets?

enter image description here

EDIT again: Right click show in finder? enter image description here

Please look into this: http://stackoverflow.com/questions/18780476/ios-7-app-icons-launch-images-and-naming-convention-while-keeping-ios-6-icons/22353990#22353990 — msmq, Apr 03 '15 at 14:19
@msmq thanks for the response, please see my edit, because I can't drag the needed icon into the `Unassigned` image part for some reason. And I believe I have the correct image size and everything? — SRMR, Apr 03 '15 at 14:26
Try by right click and select Show in Finder option and just add that icon there; Hopefully, it will be fixed. — msmq, Apr 03 '15 at 14:46
I added an image above, I'm not sure how I'd click Show in Finder because its grayed out? — SRMR, Apr 03 '15 at 14:48
Just try this with some other icon; because, location will be same for all the icons. — msmq, Apr 03 '15 at 14:50
If its asking for a 44 2x icon (which maybe it isn't) I already have it in that folder? — SRMR, Apr 03 '15 at 15:56

I had the same issue! The solution that worked for me was pretty easy:

Just select the unassigned image and delete it via delete button. Clean and Build. Done.

Hope this helps!

How do you delete something via backslash exactly? I've never heard of that before? @Bernard – SRMR Sep 09 '15 at 22:55

@SRMR backslash means delete button on your keyword mate. – Bernard Sep 10 '15 at 03:19
I can't find solution more easier than it :). – Huynh Inc Oct 16 '15 at 08:07
Thanks @esvau for the help! – mediaguru Mar 31 '17 at 04:29

how you are getting image back after deleting, I have 100 images in the assets so do i need to reset all by doing this? – Shrikant K Aug 07 '18 at 05:19

(That's assuming you didn't miss any of the required images)

I had this problem a while ago: I went into the media.xcassets directory and checked the contents.json file, where I found some entry with "unassigned" set to TRUE. I removed it and it removed the compiler warning.

Hope you got stuck in that same scenario so you will also be able to fix it.

I do see that in my `contents.json` file, when you say "I removed it" what do you mean by that, like remove the image in Xcode or edit that json file or something else? Thanks! – SRMR Apr 03 '15 at 14:29
I had something like { "idiom" : "universal", "unassigned" : true } which I removed from the contents.json file. – Darkseal Apr 03 '15 at 14:30
I have: ` { "size" : "44x44", "idiom" : "watch", "scale" : "2x", "unassigned" : true, "role" : "appLauncher", "subtype" : "42mm" }` – SRMR Apr 03 '15 at 14:31
But if I remove that, is it removing something important I need because it has to do with some sort of `appLauncher` icon that will need to be there? – SRMR Apr 03 '15 at 14:31
Nothing "needed", as 44x44@2x are flagged as optional in the official docs: https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/IconMatrix.html But I understand it could be better for you to look for a less of a workaround solution before resolving to this one. In my scenario it had something to do with a Car App/Car UI icon (also optional), so I was glad to remove that since I didn't need to support anything like that. – Darkseal Apr 03 '15 at 14:33
These are in the WatchKit part, does the doc speak to those too? – SRMR Apr 03 '15 at 14:35
I'm assuming deleting the `Unassigned` with the delete button would be the same thing as editing the json file right? – SRMR Apr 03 '15 at 14:35
It couldn't be done from the GUI at that time: I guess now we can. – Darkseal Apr 03 '15 at 14:36
I guess I'm just wondering why I need the 38mm 40 app launcher but wouldn't need the 42mm 44 app launcher, it makes sense that I'd need both right? – SRMR Apr 03 '15 at 14:37
` { "size" : "40x40", "idiom" : "watch", "scale" : "2x", "filename" : "Icon-40@2x.png", "role" : "appLauncher", "subtype" : "38mm" },` – SRMR Apr 03 '15 at 14:37
Did you try to "manually" route the json to an image file with the right characteristics? I would try that and see what happens, maybe it's a GUI bug you've hit. – Darkseal Apr 03 '15 at 14:38
Yeah that makes sense too I'll try that! – SRMR Apr 03 '15 at 14:40

I had to

right click on one of the images in the lower row (with "unassigned" written under the row)
select "Universal" to unselect it
right click and
"Universal" again to select it
- This changed the top row to show 3 empty boxes that were empty
Drag each of the images from the unassigned row to the universal row

Though, I don't know why those menu options are disabled in the original question...

Remove all "unassigned" photos from the asset catalog. It shouldn't appear there (click "Remove Selected Items" on your screenshot).

I had old icon files (no longer needed) in the folder where contents.json is located. I removed those files in Finder and the issue was solved.

My case is: My Macbook is running out of memory, so every time I restart the computer. I don't understand how the icloud driver erased or replaced all the data in the Contents.json file in the folder:

Runner> Assets.xcassets> AppIcon.appiconset (I dev with Flutter).

So the solution for my case is I have to bring the Contents.json file back from the back up and it works normally.

In my case I accidentally removed some assets and then returned them by means of git (just reverted deleted files from Xcode's Source Control tool) – the image files came back, but the asset didn't work and I had the same warning.

I opened the Contents.json file in the asset directory and saw that the images array was empty. I added my images there manually. For example:

{
  "images" : [
      {
        "idiom" : "universal",
        "filename" : "Icon.png",
        "scale" : "1x"
      },
      {
        "idiom" : "universal",
        "filename" : "Icon@2x.png",
        "scale" : "2x"
      },
      {
        "idiom" : "universal",
        "filename" : "Icon@3x.png",
        "scale" : "3x"
      }
  ],
  "info" : {
    "author" : "xcode",
    "version" : 1
  }
}
