'[(UIView)]' is not identical to 'UInt8' when using += in Xcode 6 beta 5. Use append method instead?

Question

I was using += to an a UIView to an array and that no longer seems to work. The line

dropsFound += hitView

Gives an error \'[(UIView)]\' is

Answer 1

That changed in the last release. From the beta 5 release notes:

The += operator on arrays only concatenates arrays, it does not append an element. This resolves ambiguity working with Any, AnyObject and related types.

So if the left side of += is an array, the right now must be as well.

so:

dropsFound.append(hitView)

Or if you really wanted to use += you could probably do:

dropsFound += [hitView]

But that would be a little silly. Use append like the error message suggests.
