# getBaseURI(completionHandler:)

## Declaration

```swift
class func getBaseURI(completionHandler: @escaping @Sendable (URL?) -> Void)
```

```swift
class func baseURI() async -> URL?
```

## Discussion

Discussion important: You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: class func baseURI() async -> URL?
