# `GSLayer removeOverlapCheckSelection:error:`

*Instance Method*

Removes overlaps between applicable paths.

## Declaration

```swift
func removeOverlapCheckSelection(_ checkSelection: Bool) throws
```

```objc
- (BOOL) removeOverlapCheckSelection:(BOOL) checkSelection error:(NSError **) error;
```

```python
removeOverlapCheckSelection_error_(checkSelection: bool) -> tuple[bool, NSError]
```

## Parameters

- `checkSelection` — Whether to restrict the operation to paths containing selected nodes.
- `error` — On output, a pointer to an error object that describes why the method failed, or `nil` if no error occurred. If you are not interested in the error information, pass `nil` for this parameter.

## Return Value

Whether the operation completed successfully.

## Discussion

When selection checking is enabled but no path is selected, all applicable paths are processed.
