Swift编译错误: Cannot find an initializer for type ‘[(String)]‘ that accepts an argument list of type ‘(LazyForwardCollection<MapCollectionView<Dictionary<Int, String>, Int>>)‘
错误代码:
var dict = [1: "m", 2: "i", 3: "i",4: "s"]
let dictKeysArray = [String](dict.keys)
根据字典字面量推断,该字典的类型是<Int: String>.即key为Int类型.错误的原因就是你用Int类型的初始化了key,现在又用String类型的取.所以会报该编译错误.
正确写法:
let dictKeysArray = dict.keys
或者将String改成Int.版权声明：本文为博主原创文章，未经博主允许不得转载。
