Errors in Xcode Apps since High Sierra update

AppleScript In Xcode
#1

Since I’ve updated to High Sierra 10.13.6 and Xcode 9.4.1, each of my AppleScriptObjC apps returns this two errors at start up:

MessageTracer: load_domain_whitelist_search_tree:73: Search tree file’s format version number (0) is not supported
MessageTracer: Falling back to default whitelist

Some of those apps consist in a single window containing a table.
They return the following error at launch, apparently as many times as there are rows in the table:

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

Does anyone have a clue on this?
Google is of no help.

#2

The latter one can just be ignored. I don’t know about the first, but if it doesn’t cause any problems, you can probably ignore it too.

#3

I’m not sure.
When running the app from Xcode (Build & Run), the data is significantly slower to load (x20).
When launched as standalone app, it’s not obvious (± 1s instead of 0.4s).
But there is no freeze or any unexpected quit…

:wink:

#4

As Shane already said, you can ignore it.

These messages were littering AppleScript logs on High Sierra (and possibly also on Sierra, I don’t remember by now). Apple fixed it on Mojave.

#5

Hi leo,

Good to know that it’s fixed in Mojave.
I am considering to update to this version.
I am a bit worried by the fact that there can be problems with Adobe CC and Office 365 apps.

But since Catalina is out, there’s hope…
Thanks.
