- 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
