在我的应用程序中，我有一些代码来获取中的主机范围URL。看起来像这样：

private func rangeOfHost(text: String) -> NSRange? {
    let url = URL(string: text)
    if let host: String = url?.host {
        if let range = text.range(of: host) {
            return NSRange(
                location: range.lowerBound.encodedOffset,
                length: range.upperBound.encodedOffset - range.lowerBound.encodedOffset
            )
        }
    }
    return nil
}

Xcode一直警告我'encodedOffset' is deprecated: encodedOffset has been deprecated as the most common usage is incorrect. Use utf16Offset(in:) to achieve the same behavior.。但是，我不清楚如何用这些建议替换那些encodingOffsets。有任何想法吗？
