I'm amazed more people aren't pissed off about this. I cannot believe how poorly this came out in iOS 8.
I consistently have to quit the messages app just to be able to type using SwiftKey. It even affect the Mail app pretty regularly now. And of course, half the the time, I can't start a Spotlight search.
It's pretty bad really, and I'm hoping that iOS 8.3 is the update that takes care of this. iOS8 has been the buggiest iOS I've ever experienced.
Third Party keyboards?
How about Apple's OWN standalone keyboard. For major data input, I currently use an Apple keyboard with my iPad Air 2.
Getting an IOS device to recognize my Apple keyboard can be an exercise in total frustration.
On top of that is the need to use the touch interface for input, and the related difficulty of getting the on-screen keyboard to pop up when I want to use an emoji or something similar.
I'd like to see Apple address this seemingly simple issue with their own keyboards before I have any faith in their ability to deal with third party keyboards...
