感谢 vacawama 和 Edmar，他们都帮我找到了解决方案，如下所示:

if let unicode = definition["unicode"] as? String {
    if let int = Int(unicode.replacingOccurrences(of: "U+", with: ""), radix: 16) {
        if let scalar = UnicodeScalar(int) {
            let string = String(scalar)
            emoji.text = string
        }
    }
}
