Upgrade to iOS 10

[dotemacs]

Started this issue in order not to hijack the issue #81

To update to iOS 10 it's not a big deal, you just have to select what OS version to target.

However you'll get these two warnings (but despite them, the app will build run in the simulator):

...replete/Replete/AppDelegate.m:243:52: 'UIAlertView' is deprecated: first deprecated in iOS 9.0 - UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead

and

...replete/Replete/AppDelegate.m:264:45: 'applicationFrame' is deprecated: first deprecated in iOS 9.0 - Use -[UIScreen bounds]

Fixing those issues is not that hard, but I just didn't get around to it yet.

That's cool. I wonder if we even need to upgrade—as it stands now Replete works on iOS 8–10.

Of course, as you mention, #81 and Ejecta might force the issue.

This will be taken care of via a change in the pod file as in sherbondy@91e2329#diff-4a25b996826623c4a3a4910f47f10c30R2
