"Month 13 is out of bounds" on app launch indicates framework is broken

Number:rdar://35792221 Date Originated:2017-12-01

Product:Xcode / Cocoa framework Product Version:
Classification:Bug Reproducible:Always

Whenever you launch an app since today, Dec. 1st 2017, the message "Month 13 is out of bounds" is printed to the console, indicating something is broken on the inside.

Note that the message is emitted before NSApplicationDelegate.applicationWillFinishLaunching(_:) is called, which I verified by setting a breakpoint.

Steps to Reproduce:

- Create empty macOS Cocoa app template
- Launch

Expected Results:

The app would start, no console output shown.

Actual Results:

The app starts, but the console prints "Month 13 is out of bounds".


Version 9.1 (9B55)


Looking at the system console output, this message is all over the place.
