# decodeInt32(forKey:)

Decodes a 32-bit integer value associated with a given key.

## Declaration

```swift
func decodeInt32(forKey key: String) -> Int32
```

## Parameters

- `key`: A key in the archive within the current decoding scope. key must not be nil.

## Return Value

Return Value The 32-bit integer value associated with the key key. Returns 0 if key does not exist.

## Discussion

Discussion If the archived value was encoded with a different size but is still an integer, the type is coerced. If the archived value is too large to fit into a 32-bit integer, the method raises an NSRangeException.
