How can I cast an array initially declared as container for Any object to an array of Strings (or any other object)? Example :
var array: [Any] = []
.
.
.
array = strings // strings is an array of Strings
I receive an error : "Cannot assign value of type Strings to type Any"
How can I do?
You can't change the type of a variable once it has been declared, so you have to create another one, for example by safely mapping Any items to String with flatMap:
var oldArray: [Any] = []
var newArray: [String] = oldArray.flatMap { String($0) }
Updated to Swift 5
var arrayOfAny: [Any] = []
var arrayOfStrings: [String] = arrayOfAny.compactMap { String(describing: $0) }
You can use this synatic sugar grammar. Still one line of code :)
var arr: [Any] = []
var strs = [String]()
arr = strs.map {$0 as! [String]}
[String]. Is it really needed? And I think you mean strs.map instead of arr.map? :)
It can be so annoying to declare that I've resorted to declaring the data in a pList file and then simply reading it in to the variable.
You can use `contentsOfFile.
