Ambiguous Use of Subscript - only happens during archive

this used to work until i upgraded to xcode 7.3 a few days ago. It compiles and runs fine up until I need to archive the project. During the archive I get a "Ambiguous Use of Subscript" error on the second question mark?

if let address = placemark.addressDictionary?["FormattedAddressLines"]?[1]
{
//do something
}

Any idea on how to correct this?

Ambiguous Use of Subscript means that the compiler could not infer which subscript you want to use. It looks like the type of placemark.addressDictionary?["FormattedAddressLines"] returns is unclear to the compiler.

Try breaking it up like: 

let addressLines = placemark.addressDictionary?["FormattedAddressLines"] as? [String]

if let address = addressLines?[1]
{
//do something
}

I haven't tried this so I'm not 100% on the syntax. But this would force the type to be a string array which (I think) is what you're expecting to get back.
