问题
We have an app that is working properly with the UserNotification.framework being linked as required framework in Xcode 9. Everything works smooth here.
Now we are switching to Xcode 10. But there linking this framework as required leads to
dyld: Library not loaded: /System/Library/Frameworks/UserNotifications.framework/UserNotifications
Referenced from: /var/containers/Bundle/Application/1D41BD68-9B88-4D5D-B7AB-0D1C31979964/App.app/App
Reason: image not found
If I switch it to optional push notification (via Intercom) won't work anymore.
What is the reason? How can we fix that? Why is it even working in Xcode 9?
Update #1
using
@import UserNotification
does not fix it
Update #2
Its fixed by importing and using it actually (in AppDelegate.m) like this
UNNotificationRequest* unr = [UNNotificationRequest alloc];
unr = nil;
Why?
It is related to the same issue I have experienced already.
CABTMidiCentralViewController used in Storyboard only working if using code reference
Update #3
More generic question
Xcode sometimes removes linked library
回答1:
UserNotification SDK is available on iOS 10+, Try to update the deployment Target to iOS 10 +
回答2:
Can your please try removing the framework and adding that again ? I just created a new project this framework added in Xcode 10 and was able to run in the device without any errors.
