“Your binary is not optimized for iPhone 5” after I upload an app with xcode 6.0.1

We faced the same issue and couldn’t solve it after trying many solutions, we believe it’s a kind of bug in App submission.
But we found a workaround which can keep launch images localized and pass the submission verification.


Xcode 6.1 (6A1052c) with iOS 8.1 SDK


Have following properties in your “*-info.plist” file.

  1. Go to your target’s settings and in our standard scenario (localize
    launch images, which uses “UILaunchImages” in “*-info.plist” but not
    image assets), it should look like the image
    enter image description here

  2. Change the setting to use image assets (Note: after this step, Xcode will automatically REMOVE the “UILaunchImages” properties in your *-info.plist file. So please BACKUP the properties first.)

  3. Go to the “LaunchImage” assets (can click the arrow button on the right) and fill with images from one of your *.lproj folder.
    enter image description here

  4. Now, go to the “LaunchImage” folder which contains images and “Contents.json” file.
    enter image description here

  5. Remove ALL the launch IMAGES just added, but keep the “Contents.json” (and it’s content) file.

  6. Check the “Contents.json”, it should contains properties like image below
    enter image description here

Double check following items:

  • Localized launch images in resource folders (en.lproj, ja.lproj, etc.)

  • *-info.plist contains “UILaunchImages” properties

  • Project setting uses image asset for launch images

  • “Contents.json” in “LaunchImage” asset folder, and the folder DOES NOT really have launch images

Now you can have a try for localized launch images and submit the binary to iTunes Connect. In our App, the workaround did work for “localized launch images” and “submission successful“.

It should be a trick for avoiding the bug in submission checking.

Since the workaround above doesn’t change any resource, except making the checking thinks we use image assets, we are more convinced that there are some bugs in Apple’s checking.
