PSA: If you're using a URL that begins with "prefs:" or "App-Prefs:" you will be rejected.
It doesn't matter if you're trying to help a customer navigate a byzantine maze of switches and knobs to do the thing they want. You will be rejected.

The launch screen cache on iOS can be a pain when you want to quickly iterate while creating a new launch screen in a storyboard. Today I learned how to fix that 😄

To better understand UIViewController presentation styles, I made a demo app and open sourced it: github.com/an0/ViewControlle….
It also serves as a handy template project for filing VC presentation related bug reports.

Debug iOS 13 devices using Xcode 10:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

I'm 1 month old! That means today is the very last day for the 50% launch discount on standard listings. As of tomorrow, the price will be back to normal! Soooooo... Today would be a great day to go post your job. iosdevjobs.com/post-a-job/

It looks like NSData.description has changed when linking against iOS13/Catalina, so if you rely on that to generate a string version of your push token, you’re gonna have some issues 😬

Hope you all had a fantastic #wwdc and it may sound obvious, but we should have something related to #SwiftUI at @iosconfsg. However, instead of having SwiftUI 101, I would love to have some talks about the experiences you all will have with it from now until the conference.

Be aware of the behavioral changes in iOS 13 in UITableViewCell! The layoutMargins are different! Check out the release notes under UIKit here: developer.apple.com/document…

Working Copy development started as a response to the World Wide Developer Conference 2014. During #WWDC19 the Pro Unlock is 25% off to celebrate.
Please tell your developer friends.

If you want to share a subscription between iOS and Mac/Catalyst, you’ll have to do it all yourself. Apple has no solution for that yet. iCloud Containers are one option, but I’ll probably go with @RevenueCat – at San Jose, CA

If you’ve been thinking about buying my book on Auto Layout now would be a great time. Get 20% off until midnight Sunday 2 June in my pre-WWDC sale 🎉gum.co/albook/WWDC

Good News! If you're using Swift, you will probably be glad to know that
isDate(_ date1:, inSameDayAs date2:) -> Bool
isDateInToday(_ date:) -> Bool
are available on Calendar.
So, we don't need to write these ourselves.
Please stop writing these yourselves.

For example:
• Have the same animation in different layers you want to be in sync w/ each other? Set the layer’s beginTime to the same value
• Want to pause a layer’s animation or drive it based on interaction? Set its speed to 0 and its timeOffset to whatever you want

… I just realized that you can actually click the “hardware” buttons on the chrome of the iOS simulator (lock, vol up, vol down, lock)
I thought they were just … you know … chrome. 😳

This is spot on. Try to stick to URLSession.
A lot of people are cargo-culting best practices from 2011, or grasping for features they don’t use.

TIL: po [NSNotificationCenter defaultCenter] actually lists all observers. Great for finding accidental nil objects (which are represented by the sentinel kCFNotificationAnyObject #cocoa #objective-c
