Hello @kdubb,

Thanks for this pull request of high quality! It looks like it should be merged in shortly.

One Travis check has failed, though. When I run make test_framework_GRDBtvOS_minTarget with Xcode 10.2.1 on my machine, I get the following output:

xctest (82461) encountered an error (Failed to load the test bundle. (Underlying error: The bundle “GRDBtvOSTests” couldn’t be loaded because it is damaged or missing necessary resources. The bundle is damaged or missing necessary resources.

Are we sure tvOS 9.0 is testable?

@groue Truth be told I didn't run it against tvOS 9.0 locally; I was relying on Travis to test permutations.

I cannot get tvOS 9.0 to run either so I bumped the minimum to 10.0

That's what Travis is for :-)

Thank you very much @kdubb. Hey, this is your second merged pull request here, after #160. Would you like a push access to the repository? Just drop me a line, and I'll invite you.

Shipped in v4.3.0
