[Dave Kilroy]

tldr - don’t use Xcode 8.3 yet, you can still build for iOS 10.3



Bill the Release Notes are a good place to check such issues. The following is an extract for release notes for LiveCode 8.1.4(rc1)

iOS

iOS deployment is possible when running LiveCode IDE on a Mac, and provided Xcode is installed and has been set in LiveCode Preferences (in the Mobile Support pane).
