# insertValue(_:at:inPropertyWithKey:)

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

## Declaration

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

## Discussion

Discussion The method insertIn<Key>:atIndex: is invoked if it exists. If no corresponding scripting-KVC-compliant method (insertIn<Key>:atIndex: ) is found, this method invokes mutableArrayValueForKey: and mutates the result. note: Prior to OS X version 10.4, this method did not invoke -mutableArrayValueForKey:.
