You can use zip to combine your two arrays, and thereafter apply a .flatMap to the tuple elements of the zip sequence:

您可以使用zip来组合两个数组，然后将.flatMap应用于zip序列的元组元素：

let array1 = ["Albert","Bobby"]
let array2 = ["Charles", "David"]

let arrayMerged = zip(array1,array2).flatMap{ [$0.0, $0.1] }

print(arrayMerged) // ["Albert", "Charles", "Bobby", "David"]

Give this a shot

试一试

   var a = ["one", "two"]
   var b = ["three", "four"]

   var c = a + b
   print(c)
