基于JSON的Swift数组排序

let jsonString = """
[
    {"name": "Alice", "age": 25},
    {"name": "Bob", "age": 30},
    {"name": "Charlie", "age": 20}
]
"""

if let jsonData = jsonString.data(using: .utf8) {
    do {
        let jsonArray = try JSONSerialization.jsonObject(with: jsonData, options: []) as? [[String: Any]]
        // 对jsonArray进行排序操作
    } catch {
        print("JSON解析失败：\(error)")
    }
}

if let jsonArray = jsonArray {
    let sortedArray = jsonArray.sorted { (dict1, dict2) -> Bool in
        if let age1 = dict1["age"] as? Int, let age2 = dict2["age"] as? Int {
            return age1 < age2
        }
        return false
    }
    // sortedArray为排序后的数组
}
