What is ibtoold on Mac?

By Junaid, maker of Taskglass · Last reviewed

Interface Builder's helper in Xcode, for storyboards and XIB interface files.

ibtoold is an Xcode tool that works with Interface Builder documents (storyboards and XIB files): it renders them in Xcode's canvas and compiles them during builds. It's busy when you open or build projects with many or large interface files.
