XCode 8.2 warning: SpellChecker asset (iOS Apprentice 2: Checklists v5.0)

I’m getting weird warning spam about a failure to load a SpellChecker asset in the XCode debugger window when I run the “Checklists” app I’ve created during the iOS Apprentice 2 exercises. I suspect this is a build setting or something to do with XCode, but I can’t find a solution online. Any suggestions?

If it’s any consolation, I got that too. I googled MobileAssetError:29, and saw some posts indicating it happens when you use the Simulator, which I think doesn’t have access to WiFi. I think it is triggered by the pop-up keyboard for text entries in the Simulator. It also happens in the MyLocations tutorial, by the way. I don’t think it would happen on an iPhone.

Thanks. I’ll look to see if there’s a way to grant the simulator network access.

Hmm… the News app works on the simulator, so apparently the simulated device has network access. I’ve no idea why the call to fetch the SpellChecker is throwing a warning.

There is a lot of crap that Xcode or the Simulator prints out. Most of it you can simply ignore.

You can make it be quiet by adding an environment variable to the debug scheme: OS_ACTIVITY_MODE and its value should be disable. Be careful doing this, however, as it will also hide some errors that you may want to see.
