Description
This local is assigned and never read afterwards. Remove it, or use the value if the read was the point.
Rationale
This local is assigned and never read afterwards. Remove it, or use the value if the read was the point.
The following code illustrates the pattern detected by this rule:
@implementation Locals
// FLAGGED: Local variable declared but never read
- (void)withUnused {
NSInteger forgotten = 5;
NSLog(@"nothing to do with it");
}
