The warnings configuration we use in the PSPDFKit iOS framework - http://pspdfkit.com
//
// Warnings.xcconfig
//
// The list of warnings we (don’t) use, and the reasons why.
//
// :MARK: Warnings in use:
// :MARK: -everything
// We want the best possible diagnostics, so we simply enable everything that exists, and then opt–out of what doesn’t make sense for us.

// :MARK: - Warnings not to be promoted:

In light of git having a security vulnerability it is time to update git. This gist will do just that if you're running on a mac and prefer to use the default git installation.

If you're implementing child view controllers and want automaticallyAdjustsScrollViewInsets to work...
// This ensures that the automaticallyAdjustsScrollViewInsets magic works
// On our newly added view controller as well.
// This triggers _layoutViewController which then triggers
// _computeAndApplyScrollContentInsetDeltaForViewController:
// which finally updates our content inset of the scroll view (if any)

If you're annoyed about the incorrect arrow presentation on popovers (https://twitter.com/steipete/status/624521051855319040) use this category. Oh, and file a radar! I did.
@implementation UIPopoverPresentationController (PSPDFAdditions)
