title: In iOS set product name ,app id and code signing identity during build
body: <p>I want to set the iOS app 'product name' &amp; 'appId' &amp; 'code signing identity' during build time . I am building 2 app with same code base but 'product name', 'appId' &amp; 'code signing identity' is different .  I am manually changing the 'product name', 'appId' &amp; 'code signing identity' for each build . I want to set a parameter in code , and according to that corresponding 'product name', 'appId' &amp; 'code signing identity' should be changed during build time. Can anybody help me on this.</p>
