xcode when i run program on iphone 6 screen looks iphone 5 How to fix this?

I have a problem with an app that i created, it's developed based on a 4 inch layout, a week ago i've tested it on Iphone 6 Simulator it looked great, today when i wanted to take screenshots, the screen looks like iphone 5 screen. I've checked and unchecked AutoLayout, and size classes was disabled from the begging.

Anyone had this issue?
