I did an informal survey yesterday of some widely-used iOS apps, which happen to appear on my phone, that have been updated for iOS 9. I wanted to see which had opted out of the new App Transport Security checks in iOS 9.
The results aren’t very promising.
I'm guilty of this as well. In fact "NSAllowsArbitraryLoads" is the only Info.plist key that I've committed to memory. Time to step up my game.
