Inserting child controllers in the Auto-Layout world.
// ## inserting. this can be done in viewDidLoad
// this can be any view, here I'm adding to main view
UIView *containerView = self.view;
// load child controller
UIViewController *svc = [[UIViewController alloc] initWithNibName:nil bundle:nil];
// kill the randomness
svc.view.translatesAutoresizingMaskIntoConstraints = NO;
// add child VC to hierarchy
[self addChildViewController:svc];
// set initial rect

If you want to use Xcode's FileMerge as your git mergetool, this is how you set it up.
# Tell system when Xcode utilities live:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
# Set "opendiff" as the default mergetool globally:
git config --global merge.tool opendiff
