如何将[AnyObject]数组快速转换为字符串

Question

For example: Array like ["A12", 1, 2, "Test"]. My expected result should be able to bind in the textfield or else to get as string with component seperator (,)

Answer 1

First map the values to String values, and then just join them using separator that you like:

let description: String = ["A12", 1, 2, "Test"].map{ String(describing: $0) }.joined(separator: ", ")
print(description)

Answer 2

You can get it done with this,

    let array: [Any] = ["A12", 1, 2, "Test"]
    let tmpArray = array.map({ return String(describing: $0)})
    let string = tmpArray.joined(separator: ",")
    print(string)
