How to hide Blue line covering views in xib/Storyboard in Xcode 7.2

I have followed @Paola 's answer. but did not work for me .In addition I enabled and disabled it again than it removed blue lines. (Xcode Version 9.4)

Got to Xcode and refer screenshot

Same thing happened to me. In Xcode: Editor > canvas > show bounds rectangles. This option show/hide the blue lines.

If you found this one not work first time, try twice toggling the show bounds rectangles option. Some time this is not work in first time.

For Xcode 14 and Xcode 13 and Xcode 12, repeat this step 3 times. XCode: Editor > canvas > Bounds rectangles.

For Xcode 11 and Xcode 10, repeat this step 3 times. XCode: Editor > canvas > show Bounds rectangles. This is a bug in Xcode 11 Xcode 10.
