I have added the icon as shown in the pic below but I am still not seeing the icon in my device or simulator.
问题:
回答1:
This might be an XCode 5 bug that the added icons are not actually included in the app bundle, but you can work around it by going to Build Phases, expand Copy Bundle Resources, then press the "+" sign in the bottom to manually add the icon files to this category.
In addition iOS 5/6 seems to have a bug that the screen doesn't update the app icon even if the icon files are included in the bundle. To work around it (as suggested by josema.vitaminew at App Icon not changing when app version is updated in iOS 5 simulator) you can drag the app icon into a folder, then iOS will update the appearance of it.

If using the Asset Catalog, it might be worth also checking whether Images.xcassets
holds all your targets as shown in the below image.

Expanding on adp's answer, if anyone has switched to asset catalogs but they stopped working, and still can't find a solution for Asset Catalog, Images.xcassets, AppIcon or LaunchImage not working, here is a reproduction of the same problem I encountered, and the solution:
I had upgraded to Xcode 6 and opened a project created by an earlier version (4 or 5, not sure) and no matter what I did, AppIcons and LaunchImages absolutely would show up when I ran the app in either iOS Simulator or the device.
I tried Xcode->Product->Clean, Xcode->Window->Organizer->Projects->Derived Data->Delete..., relaunching Xcode and the iOS Simulator, then rebuilding and relaunching the app (failed).
I tried "Reset Contents and Settings..." in iOS Simulator and even deleting ~/Library/Developer/Xcode/DerivedData//Build/Products/Debug-iphoneos and relaunching the app (failed).
I tried archiving the project, hoping that it was just an issue with the iOS Simulator, but the icon in the Organizer-Archives window was still shown as the default white square with lines, confirming that the icon would also not show on a device (a helpful trick to have when no device is handy). (failed).
I tried choosing "Don't use asset catalogs" in Target Settings and creating a new AppIcon-2 and LaunchImage-2 (failed). -this is what cost me at least 2 more hours, because this should have worked and the fact that it didn't revealed the bug in Xcode but I just couldn't see it-
I tried creating a new project from the single view template and compared all of the Info.plist settings (failed).
I tried comparing the new project's Contents.json with mine in Images.xcassets (failed).
I tried dragging the images from the left sidebar Navigator into the AppIcon image wells, hoping that they were just not being copied in a build phase for some reason (failed).
Finally in exasperation at the thought of having to create a new project just to fix the icons, I tried deleting Images.xcassets in the left sidebar Navigator and choosing "Move to Trash", then quitting Xcode and relaunching in case it cached anything. Then when I went to click the App Icons Source popup menu, it only showed "Don't use asset catalogs". I had to select it in order to bring back the "Use Asset Catalog" button. Then I was able to create new AppIcons and LaunchImages, drag images to the wells, build and launch the app in iOS Simulator and finally see icons appear properly.
So the problem appears to be with how Xcode stores Images.xcassets inside the project, and not with target membership, derived data, or anything in Images.xcassets itself. You must remove your assets file and create a fresh one, then drag images to wells by hand again.
It took me 3 hours of research to solve something that should have "just worked" and the entire process of having to manually create individually sized art assets has been so tedious over the years that it has personally cost me countless hours of busywork.
Hopefully this bug workaround helps someone avoid the frustration I went through. I can't help with the friction of manually sizing art assets, but I highly recommend the Icon Slayer website to automate that (of which I have no affiliation).

I have encountered the same problem when the project is switching from xcode5 to xcode6 . The solution is just click on the icon in the image asset,open the right panel , just tick the iOS version option in the panel,add the icons that are blank run it again ... It worked for me

I want to add my solution, where the problem is only isolated to the iPad, my app icon will not show only for iPads. After trying all the solution above, and I looked in the info.plist and found this flag that was not there before the problem with iPads. A new key/value has been added called "CFBundleIcons~ipad" without my knowledge and had nothing as it's value. Removing the key helped resolve my issue.

According to Apple Docs, the icons must be placed on the root level of the app files.
IOS/Xcode will not go under directories to search your image.
Solution is to move the images onto the root of your application i.e. where your source files are, or you can create references in the same way.

I had the same problem and after a couple of hours finally I could resolved it, copying an old -info.plist from one of my backups project and replace it, this works fine for me. Regards

My issue ended up being I had used jpg images, rather than pngs.
回答9:
For me, it was a much simpler solution than the others listed here. I had simply got the assets the wrong size. I had not paid attention to the multipliers that are necessary (e.g. 2x or 3x) and therefore the build was generating a warning for the incorrect asset sizes (which I had ignored). In my case, I corrected the image sizes and voila they appeared in the simulator.
回答10:
For a macOS/OSX application, you also need to always add a 128 pixel size (and 2x), you can not only use a 512 pixel size and expect it to size down.
回答11:
If your app icon has any transparency then it won't work. Check it!
回答12:
I had all the images in the relevant folders and when I right clicked on the empty icon image in Images.xcassets/AppIcon
and chose show in finder
it would find the image correctly and show it, but for whatever reason it wasn't adding correctly to the project.
After trying a lot of different things above I simply dragged the images from finder into the AppIcon area and it worked.

If you are using cocoapods be sure to check this answer from a related question. After many lost hours, this is what fixed it for me.

In my case, I just needed to clean and rebuild my project.

Xcode 9.3:
- Open your project and add AppIcon images.
Click on general, go to "App Icon and Launch Image"
Click "App Icon resource" and add AppIcon (In my case it added AppIcon-1, so you can use that on rename that and do above step again).
