Xcode warning “Property access results unused - getters should not be used for side effects”

Question

I\'m getting this warning when I\'m calling a local routine.

My code is this:

-(void)nextLetter {
    // NSLog(@\"%s\", __FUNCTION__);
    currentLetter

In newer Xcode versions, even the [object method]; may trigger the warning. But sometimes we actually do need to call a property and discard the result, for example when dealing with view controllers and we need to make sure the view is actually loaded.

So we were doing:

// Ensure view is loaded and all outlets are connected.
[self view];

This now also triggers the “Property access results unused - getters should not be used for side effects” warning. The solution is to let the compiler know it's done intentionally by casting the result type to void:

(void)[self view];
