# insertValue(_:inPropertyWithKey:)

Inserts an object in the collection specified by the passed key.

## Declaration

```swift
func insertValue(_ value: Any, inPropertyWithKey key: String)
```

## Discussion

Discussion The method insertIn<Key>: is used if it exists. Otherwise, raises an NSUndefinedKeyException. This is part of Cocoa’s scripting support for inserting newly-created objects into containers without explicitly specifying a location.
