I am trying to submit my first app to the App Store but when I try I am getting the following error:
ERROR ITMS-9000: "Your binary is not optimized for iPhone 5 - New iPhone apps and app updates submitted must support the 4-inch display on iPhone 5 and must include a launch image referenced in the info.plist under UILaunchImage with a UILaunchImageSize value set to {320, 568}. Launch images must be PNG files and located at the top-level of your bundle, or provided within each .lproj folder if you localize your launch images.
I'm using SDK 8.1. Deployment target is 8.0. Launch images are set by storyboard launch screen file. There is no obsolete launch screen images and I don't plan to add them because target system is iOS 8+.
What is wrong? Xcode version 6.1 (6A1052d).
