Remember those innocent days a few short months ago when we all spotted the new safeAreaLayoutGuide and thought: "Our constraints are now with the top and bottom anchors of the safe area layout guide. This is not a big change..."

Oh, sweet naiveté. Did anybody actually call out in advance that subtle little change was foreshadowing THE NOTCHALYPSE? Yes, yes, every time something changes it brings out the fear and loathing no matter what it is, but the level of OMG NEVER BUY APPLE AGAIN ... we saw this time, that was unprecedented. Personally, we think a phone with a bat-eared screen is kinda neat, but we're weird.There's a certain level of enthusiasm out there for clipping and masking and otherwise working around the new roundedness and notchedness ... but we think Marco has it right here:

This is the new shape of the iPhone. As long as the notch is clearly present and of approximately these proportions, it's unique, simple, and recognizable.

It's probably not going to significantly change for a long time, and Apple needs to make sure that the entire world recognizes it as well as we could recognize previous iPhones.

That's why Apple has made no effort to hide the notch in software, and why app developers are being told to embrace it in our designs...

So, we've got some rewriting to do in the next few weeks to have our apps fit nicely into The Brave New Notched World, and you probably do too we imagine; let's see what resources are out there!

First off, go over the relevant stuff over at the mothership:

• Building Apps for iPhone X

• Designing for iPhone X

• Updating Your App for iOS 11

• Human Interface Guidelines - iPhone X

• Positioning Content Relative to the Safe Area

• The great PaintCode people have updated their  invaluableThe Ultimate Guide To iPhone Resolutions and also have specs for all the Notch attributes at iPhone X Screen Demystified.

"Adaptivity is an app for developers and designers to visualize how iOS's Size Classes and margins for layout and readable content look on real devices and how they change with respect to orientation, iPad Slide Over/Split View and Dynamic Type size changes..."
