XCode 6.3 Warning : Comparison of address of 'myObject' not equal to null pointer is always true

Question

After updating to XCode 6.3, compiler started giving this warning.

Comparison of address of \'myObject\' not equal to null pointer is always true.

Answer 1

Correct way of checking the pointer is

if (anotherInView != nil) {
}

You are comparing address of a variable with the NULL. Every variable has an address you can't have a variable whose address is NULL, you can have a variable whose value is NULL

Also anotherRect != NULL is again not valid. anotherRect will always have a value as it's a struct
