-[UIApplicationDelegate applicationWillEnterForeground:] docs are wrong about UIApplicationWillEnterForeground notification

Number:rdar://49817144 Date Originated:4/11/2019
Status:Open Resolved:
Product:UIKit Product Version:iOS 12
Classification: Reproducible:Always

Docs say "The app also posts a UIApplicationWillEnterForegroundNotification notification shortly before calling this method to give interested objects a chance to respond to the transition."

Steps to Reproduce:
1) Register observer on UIApplicationWillEnterForegroundNotification with NSLog
2) Add NSLog in -[UIApplicationDelegate applicationWillEnterForeground:]
3) See which log is sent to stdout first

Expected Results:
log call from UIApplicationWillEnterForegroundNotification observer happens before the one in applicationWillEnterForeground:

Actual Results:
applicationWillEnterForeground: log happens first

iOS 12
