Xcode error 90086

Hi, i keep getting this error in Xcode when i try to upload my app to testflight. Was looking into whole day, cant find a way to fix it. Seems thats new thing from June 1st.

ERROR ITMS- 90086:-Missing 64-bit support - Beginning on February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code.

I did all sugested things on stackoverflow etc.
Thanks for any help.

Go to “File” → “Build Settings…” and choose “Player Settings…”.
In “Settings for iOS” open “Other Settings” and change:

  • “Scripting Backend” from Mono(2.x) to IL2CPP
  • “Architecture” to Universal

I was able to submit my application to TestFlight. This is blog post related to this problem: Apple iOS 64-bit support in Unity | Unity Blog
