note:

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:

func isPreferredAvailable() async -> Bool

For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.

Call the method as follows:

func obtainPreferredAvailable() async -> (NSString?) {
    let client = THClient()
    var bIsPreferredAvailable:Bool?
    bIsPreferredAvailable = await client.isPreferredAvailable()
    let str = ((bIsPreferredAvailable == true) ? "true" : "false")
    return str as NSString;
}
