I am having trouble figuring out how to switch to Safari from a native app in iOS 7+. I've used `UIApplication.sharedApplication.openURL()`, but that opens a new tab. I would like to return the user to the current page he/she was viewing before without opening a new tab. I found [this](https://stackoverflow.com/questions/6821227/can-an-ios-app-switch-to-safari-without-opening-a-page) SO post, but it is a few years old, so I was hoping things have changed since then.

Here is the workflow I am envisioning:

1. User taps on a link on an HTML page on Safari to open/install my app
2. User performs an action on my app
3. After the user is done performing the action, my app opens Safari automatically, and the user is back on the page where he/she left off

Google has somehow done this with their Google Maps app. If you search for an address on google.com on Safari, you can tap on the map that appears in the search results, and it will open the Maps app. At the top of the Maps app will be a "Return to Safari" bar that you can tap. Once you tap it, you are returned to Safari without loading another tab. I can't seem to find anything regarding how Google did this. If I can replicate that behavior in my app, that would work just fine.

Any help would be greatly appreciated!
