Apple has released XCode 10 and our development teams are planning on using it for our upcoming releases. However when we review the release notes for TBB 2019 Update 6 we see that support is only offered for:
macOS* 10.12, 10.13
Xcode* 7.0 - 9.1
Are there known issues with OSX 10.14 (or later) or XCode 10? If so could you please post them?
