Swift中的遍历操作是编程中非常基础且关键的有些，

数组遍历

1. 老一套的for循环: swift let fruits = for in fruits.enumerated { print: \") }

   

2. for-in循环: swift for fruit in fruits { print }

3. forEach方法: swift fruits.forEach { fruit in print }

字典遍历

范围遍历

1. for-in循环遍历区间: swift for i in 0..<5 { print }

2. 步进遍历: swift for i in stride { print }

字符串遍历

1. for-in循环遍历字符串: swift let str = "Hello, Swift!" for char in str { print }

2. 遍历字符串的字符集合: swift for char in str { print }

元组遍历

1. for-in循环遍历元组: swift let tuple = for in tuple { print: \") }

以上这些个遍历方式是Swift编程中常用的，掌握它们有助于编写高大效且容易于搞懂的代码。
