# getObjectValue(_:for:errorDescription:)

NSDateComponentsFormatter currently only implements formatting, not parsing. Until it implements parsing, this will always return NO.

## Declaration

```swift
func getObjectValue(_ obj: AutoreleasingUnsafeMutablePointer<AnyObject?>?, for string: String, errorDescription error: AutoreleasingUnsafeMutablePointer<NSString?>?) -> Bool
```
