Xcode 6 (beta 3): Unsupported pixel format in CSI or Unable to create unsliced image from csi bitmap data

Question

When loading UIImages with png images in Xcode 6 beta 3 in Swift as follows:

    PipsImg = (UIImage(named: "Die-1"))

or

    PipsImg = [(UIImage(named: "Die-1")),(UIImage(named: "Die-2"))]

from associated images stored in the Images.xcassets folder, I receive the following fatal runtime errors:

 SimpleAnimation[680:60b] Unsupported pixel format in CSI
 SimpleAnimation[680:60b] Unable to create unsliced image from csi bitmap data.

this appears to be resolved in beta 4, however will leave in place for a bit as sometimes these regress

Those aren't fatal errors, the program keeps running, although those images don't get displayed. — progrmr, Jul 09 '14 at 03:16
@MatthiasBauch - questions about beta software are still worth answering, who knows if or when it will be fixed or become obsolete ([see discussion on meta](http://meta.stackoverflow.com/a/258515/1693173)) — progrmr, Jul 09 '14 at 03:20

This is caused by a bug in Xcode 6 (beta 3 at this time). It appears to occur only if your build target is iOS 7.x

To work around this issue:

1) delete the files from the Images.xcassets container.

2) place the images directly into the "Supporting Files" folder.

Note: It is not required to add the ".png" extension within your code, making this a clean workaround.

Please create a RADAR (bug report) to Apple.

If you continue to get the same errors as the original post then you need to go to your Organizer (under the Window menu) and delete the derived data. – dnevins Jul 15 '14 at 05:04

This is ridiculous, messes up the projects. I'll just wait for the next Beta. – Legoless Jul 16 '14 at 08:25

This *bug* seems to be fixed in beta 4 – pyrou Jul 21 '14 at 21:06
I'm currently running beta 5 and just ran into this issue again. It would also appear that the workaround does not work for me either. Anyone have a Radar id I can reference when I file my own? – jpittman Aug 19 '14 at 23:53

Actully I am using Xcode 6.1.1 with iPhone 5C running iOS 7.0.5 and its crashing so It may not just be related – Kamar Shad Feb 27 '15 at 09:24
I'm in Xcode 7.1. This works building for iOS 9, but fails building for iOS 8. – Alex Zavatone Apr 01 '16 at 18:02

XCode 6.0.1 still have this problem. If you add .jpg to Images.xcassets and try to install app to the iOS 7 device.

To fix it just convert .jpg to .png

XCode 6.1 also has it but when I converted jpg to png there was no problem. Always using png on xcassets and I accidentally included 2 jpg files and had this issue. It definitely is an issue of xcassets with jpg files. – Pericles Oct 21 '14 at 13:30

Apple engineer's response:

The issue is that iOS 7 apps cannot have JPEG images in the CAR file. actool should have copied the JPEG as a loose image into your app's folder. To work around this issue, you should either convert the image to a PNG or include the JPEG as a resource outside of the asset catalog.

I solved this problem via:

Run iOS Simulator
Reset content and settings via "iOS Simulator > Reset Content and Settings" menu.
It works.

In Xcode we now have a possibility to do a slicing for the image resources. If slicing is added the corresponding json for an image in asset catalog gets resizing info. This may look for example like this

"resizing" : {
    "mode" : "3-part-vertical",
    "center" : {
      "mode" : "fill",
      "height" : 6
    },
    "capInsets" : {
      "top" : 16,
      "bottom" : 6
    }
  }

iOS 7.0 doesn't handle slicing properly. So removing the slicing info from json may help to fix the problem (in my case that was a solution).
