I am using xcode 7.2, in xib when i insert any view, label,txtField etc., all are showing this covering blue line. now it is very hard to insert/manage new view or anything in xib due to this line.
Does anybody know how to hide these?

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.

12In case you skipped the second paragraph, it's important! Try twice! Really funny detail to need to include, but happened to me. – Dave G Feb 17 '19 at 05:14

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.

1THIS IS A BUG IN XCODE 10 & 11. You're a life saver. What kind of bug is this? – mkeremkeskin Mar 18 '20 at 05:48

Mostly this comes when you switch lower version to higher version of XCode. And use both versions at the same time. – Bijender Singh Shekhawat Jun 23 '20 at 17:38

In Xcode 14. It could be either: Editor > Canvas > Layout Rectangles or Bounds Rectangles. Uncheck both.
