How to generate strings file using ibtool? - command-line-tool

Question

I installed the command line tools in xcode 7.3 and in the command line I used the following command to generate the strings file:
ibtool --generate-strings-file testFile.strings MyController.xib
and also I tried to give the directory path for my xib:
ibtool --generate-strings-file testFile.strings UI/Screens/My\ Card/MyController.xib
I also tried the command with sudo infront of it, suggested from this answer
None of them worked.
I got the error:
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

I used the wrong location of the xib. I enetered the location of xib by seeing its heirarchy in the project navigatior in xcode. BUt the correct path can be found at File Inspector tab under Source Control option.
Select the xib file
Go to File Inspector in the Utilities section.
Look at the Location path under source control option.It will be something like:
/Users/VenkataManiteja/Desktop/iOS/MyProject/src/MyController.xib
and I changed the command to
ibtool --generate-strings-file testFile.strings src/MyController.xib
and it worked.
