Xcode 7.2 the minimum target is 9.2 iOS , how to lower it?

Hey i try to build the engine with the examples in Xcode 7.2 into the device
my IPhone is using iOS 8.2 , when i try to lower the deployment target it doesn’t give any option
is it Xcode problem or Urho3d settings ?
also i executed the cmake script like this :

meirs-Mac-mini:Urho3D meiryanovich$ ./cmake_ios.sh /Users/meiryanovich/Documents/3d/Urho3D/git/build_ios -DURHO3D_SAMPLES=1 -DIPHONEOS_DEPLOYMENT_TARGET=7.0

Have you checked the “Deployment Target” setting in the generated Xcode project?

i did try this :

but it still don’t let me to change deployment target in all the projects.

This is kind of strange and confusing .
in the documentation is written that you should build from “Build_All” target but it haven’t gave me the option to select Deployment target below the latest 9.2
BUT …
if i select individual projects for example 23_Water example i can change the Deployment target to 7.0 or 8.0 and it compiles fine but there is Deployment target bug when i try to deploy to my iPhone
i will open new thread on the subject.
