UIApplication.sharedApplication not available

Question

I\'m trying to get a reference to my app delegate from a UIViewController but I keep getting an this error message:

\'sharedApplication()\' is unavail

Answer 1

I ran into the same error when I created and added a new target to my project (a Remote Service Notification target) and added the target definition incorrectly in my podfile.

I was following directions from a third party notification platform and they were unclear as to where to place the target definition. Initially, I added the target definition within my main target, much like the Tests target definition. This mistake led me to this error.

I ended up moving the remote service notification target definition outside of my main target to the bottom of my podfile and that resolved my problem.

Answer 2

In case anyone came through this error after 3 years from the question time. Make sure that the swift file target Membership doesn't include a Today Extension.

Answer 3

Problem solved. I've been to the Build Settings of my app again and stumbled over

Require Only AppExtension-Safe API

all set to YES. The default though is NO. When I set this to NO the error disappeared.

I sure don't remember ever touching or even knowing about this but luckily now it works.
