• Array 是 value type，使用 structs 实现
• 数据类型没有隐式转换
• 对于 String，count() 的复杂度是 O(n)，每一个 Character 都是 unicode scalars 的序列
• raw values 和 associated values 的区别
• 如果必要，对于实现了 _ObjectiveCBridgeable 的 value types 会被自动桥接成 reference types
• 讲一下 unowned 和 weak 的区别
• 改 struct 的属性的方法名前要加 mutating，但如果这个 struct 用 let 声明的，改不了。修正：网友指出用 nonmutating set 也可以改属性。
• nil 和 .None 的区别
• capture list in closure
• 举一个 guard ... where 的例子
