How to change your tool bar button (run,build for testing, build for profiling,analysing) in xcode

Hi

Most of us are familiar with the run button at the top left toolbar section of XCode.But i some how changed it to test button accidentally.

Its not an issue but the small arrow at the bottom, on which you will click intuitively will disappoint you.

The trick is to do LOOOOOONG press then you will be presented with option as shown below
and you can chose from that.

A pat on the back !!
