# UTCreateStringForOSType(_:)

Encodes an OSType into a string suitable for use as a tag argument.

## Declaration

```swift
func UTCreateStringForOSType(_ inOSType: OSType) -> Unmanaged<CFString>
```

## Parameters

- `inOSType`: The OSType to convert.

## Return Value

Return Value A string that encodes the OSType.

## Discussion

Discussion The UTI functions assume that all alternate identifier tags can be represented as Core Foundation strings. OSTypes are integer-based rather than string-based, so to pass an OSType into a UTI function, you must call this function to convert it to a string.
