they believe apps are key to this.

9+DeepLink

feature

Other takeaways▪ Apple will continue pushing people to apps

Some GotCha’s


Support Multitasking in your apps!

▪ ‘participating in iOS 9 multitasking is straightforward

when you’ve adopted Apple’s best-practice

recommendations for iOS 8’

▪ Stop thinking in Orientation focus on screen size

▪Use autolayout & Size classes


Your Xamarin.iOS project might crash on iOS9!

▪Need to build with the Stable version of Xamarin.iOS

and resubmit to the App Store


Beware (unsecured) connections

▪ Apple NSSession now has ATS security and it’s enabled

by default

▪ It will fail on insecure connections

▪ This affects ModernHttpClient
