# detachDrawingThread(_:toTarget:with:)

Creates and executes a new thread based on the specified target and selector.

## Declaration

```swift
class func detachDrawingThread(_ selector: Selector, toTarget target: Any, with argument: Any?)
```

## Parameters

- `selector`: The selector whose code you want to execute in the new thread.
- `target`: The object that defines the specified selector.
- `argument`: An optional argument you want to pass to the selector.

## Discussion

Discussion This method is a convenience wrapper for the detachNewThreadSelector(_:toTarget:with:) method of Thread. This method automatically creates an @autoreleasepool block for the new thread before invoking selector.
