Equality comparison result unused in iOS 9

Question

I just moved to iOS 9 and noticed some new warnings on my old code:

description.becomeFirstResponder == YES;

Display warning 'Equality comparison result unused'

How can I handle this Warning.

Thank You!

Fix your code. The warning is telling you precisely what is wrong. — Avi, Jun 29 '16 at 11:18

If you want to assign value then you should use `=` instead of `==`. `==` is used to compare. for example if you want to use in `if statement` then use `==`. — Ketan Parmar, Jun 29 '16 at 11:31

You probably meant to assign, as in:

description.becomeFirstResponder = YES;
                                 ^

(== is the equality comparison operator).

The compiler is complaining as the result of the comparison wasn't being used, as it would be in:

if (description.becomeFirstResponder == YES) { /* do something */ }
