Swift 4の異種アレイからどのようにキャストしますか？

Question

let data = ["1", "2", 3, 4, 5]; 

var m: Int = data[3] as! Int; 

error: MyPlayground.playground:238:12: error: heterogeneous collection literal could only be inferred to '[Any]'; add explicit type annotation if this is intentional
let data = ["1", "2", 3, 4, 5];
^~~~~~~~~~~~~~~~~~~ as [Any]

Answer 1

エラーが示唆していることを試してみませんか？

let data: [Any] = ["1", "2", 3, 4, 5]; // Added explicit type annotation 
var m: Int = data[3] as! Int;
