Answer 1

Click on your project name in the left top, then on your target, and then click on the "build settings" tab

In all the option there is a "iOS deployment target" i think this is what you want ^^

Answer 2

I had the same issue. Turns out you have to download/install the newest version of Xcode from the App Store.
