New update is not compilable

[alexs555]

Hello!
Today I stuck with an issue after swift-2-old branch was dropped. Some Mirror's declaration don't work anymore, Ex:

1. let itemMirror: Mirror? doesnt compile
   https://gyazo.com/b5efc0486eaf7db664f5353661c4772b

if let value = itemMirror[param] where value is String {
return value as? String
} (type Mirror doesn't have subscript members))
https://gyazo.com/9547f3b03852993d1d49b675ad0f3a44

What can be the reason? Thank you.

Hi, thanks for reporting issue. Is it possible to actually see the code so I can try to fix it?

1 issue:

The mirror is generic type. Try Mirror?

2 Issue

Yes the subscript operator was disable for now because of new API in Swift.Mirror reflection API. It should be fixed very soon.
I'm sorry for that troubles

Take a look at screenshots attached.
Is it possible to make an Mirror var as a field in struct?

[kostiakoval]

I think it should be possible, don't see any reason why it shouldn't work

Is it possible also to return back swift-2-old branch where subscripts worked?

[kostiakoval]

I'm sorry but that branch was completely wrong and borken. That's why it was deleted.

Can you please check swift-2.0 branch.
The subscript should work there.
