# ivar_getOffset(_:)

Returns the offset of an instance variable.

## Declaration

```swift
func ivar_getOffset(_ v: Ivar) -> Int
```

## Discussion

Discussion For instance variables of type id or other object types, call object_getIvar(_:_:) and object_setIvar(_:_:_:) instead of using this offset to access the instance variable data directly.
