# LSCopyApplicationForMIMEType(_:_:_:)

Locates the preferred app for opening items with a specified MIME type.

## Declaration

```swift
func LSCopyApplicationForMIMEType(_ inMIMEType: CFString!, _ inRoleMask: LSRolesMask, _ outAppURL: UnsafeMutablePointer<Unmanaged<CFURL>?>!) -> OSStatus
```

## Parameters

- `inMIMEType`: A Core Foundation string object specifying the MIME type to consider; see the CFString Reference in the Core Foundation Reference Documentation for a description of the CFStringRef data type. Comparison of MIME types is case-insensitive.
- `inRolesMask`: A bit mask specifying the application’s desired role or roles with respect to items with the specified MIME type; see doc://com.apple.documentation/documentation/coreservices/lsrolesmask for a description of this mask. If the role is unimportant, pass kLSRolesAll.
- `outAppURL`: A pointer to a Core Foundation URL reference that, on return, will identify the preferred application for items with the specified MIME type; see the CFURL Reference in the Core Foundation Reference Documentation for a description of the CFURLRef data type. You are responsible for releasing the URL reference object.

## Return Value

Return Value A result code; see Result Codes. If no application suitable for opening items with the specified MIME type is found in the Launch Services database, the function will return the result code kLSApplicationNotFoundErr.

## Discussion
