I recently started seeing the following error when submitting an previously fine app within Itunes Connect:
ERROR ITMS-90475: “Invalid Bundle. iPad Multitasking support requires launch story board in bundle ‘com.companyname.appname.'”
After some digging into this, it turned out rather obviously to do with the new multi-tasking within Xcode 7 and IOS 9 and so you need to specify how you want your app to handle that.
To solve this error in the short term. It was as simple as disabling the handling of it, by going to the “General” tab of your target and selecting that you require full screen.
