Swift:从全名字符串中拆分名字和姓氏

func splitFullName(_ fullName: String) -> (firstName: String, lastName: String)? {
    // 假设全名中名字和姓氏之间只有一个空格分隔
    let parts = fullName.split(separator: " ", maxSplits: 1)
    
    // 检查分割后的数组是否包含至少两个部分
    guard parts.count == 2 else {
        print("全名格式不正确")
        return nil
    }
    
    // 将分割后的字符串数组转换为元组并返回
    return (String(parts[0]), String(parts[1]))
}

// 使用示例
if let (firstName, lastName) = splitFullName("张三丰") {
    print("名字: \(firstName), 姓氏: \(lastName)")
} else {
    print("无法拆分全名")
}

func splitFullName(_ fullName: String) -> (firstName: String, lastName: String)? {
    let trimmedName = fullName.trimmingCharacters(in: .whitespaces)
    let parts = trimmedName.split(separator: " ", maxSplits: 1)
    
    guard parts.count == 2 else {
        print("全名格式不正确")
        return nil
    }
    
    return (String(parts[0]), String(parts[1]))
}
