So, I have an universal project
The \"deployment info\" section looks like this: <
I found the attribute which affect the display behavior of Xcode deployment info:
In the PBXProject section of project.pbxproj file, there are lines looks like:
TargetAttributes = {
22CFA0081BE46E9A00A89E90 = {
CreatedOnToolsVersion = 7.2;
};
};
If this attribute exists in the project, the Xcode will not display "iPhone" and "iPad" buttons . Just remove these lines, then the buttons will show.
This should be a bug of Xcode7.2
