Xcode doesn't show menus for build settings options

Question

I'm using OS X 10.9.1 (Mavericks) and Xcode 5.0.2. I create a new project and in the project's Build Settings, there are no menus to choose values for the different options. Here's a screenshot...

You can see that, for example, Base SDK shows an iphoneos value, and Build Active Architectures Only shows the value YES, but it's like hardcoded, there's no menu to choose another value. Instead, when I create a new project in another computer, using also Mavericks (OS X 10.9 in this case) and Xcode 5.0.2, I get the expected menus, as seen in this other screenshot...

Why Xcode doesn't show menus for build settings options in one of the computers?

Answer 1

In Xcode, choose Editor > Show Values. That will switch from the current view style (which is "Show Definitions" that uses plain text fields) to using "Show Values", which will add in popup menus where appropriate.

Answer 2

If you want to see all the available option for Build Setting then select All option and for Target setting option click on the Target option setting
