AppleEvents: received mach msg which wasn't complex type as expected in getMemoryReference

Question

I am on Xcode 9.2, OSX, Objective-C.

Since OSX High Sierra Update, i get a lot of error messages logged like this:

AppleEvents: received mach msg whi         


        

Answer 1

Major approach on that issue (after there happened nothing for a long time): Apple responded in the forum above - it will be hopefully removed within a future update - I'll follow up on this.

A developer was worried about this message and so they opened a DTS tech support incident to verify whether it’s harmful or not.  I discovered the underlying cause of this message and I’m satisfied that it’s just log spam, that is, it’s annoying because it fills up the log with junk but it has no other deleterious effects.

There’s a bug on file (r. 33758979) requesting that we remove this log spam.

[UPDATE]: No changes in first release of XCode 10.
