Initialising empty arrays of dictionaries in Swift

Question

I\'m trying to wrap my head around initialising empty arrays in Swift.

For an array of strings it\'s pretty straight forward :

var myStringArray: String         


        

Answer 1

You can no longer use element concatenation.

class Image {}
Image i1
Image i2

var x = [Image]()

x += i1 // will not work (adding an element is ambiguous)
x += [i1] // this will work (concatenate an array to an array with the same elements)

x += [i1, i2] // also good
