FlowDeck CLI 1.21.0 is a focused update for FlowDeck Studio users and automation-heavy projects.

Smoother workflows in FlowDeck Studio

Builds, tests, runs, simulator actions, and CLI tasks started by supported agents now work seamlessly with FlowDeck Studio access. In-app workflows no longer require a separate standalone CLI license.

More reliable UI automation sessions

UI automation now tracks active sessions per simulator, reducing stale-session and wrong-simulator errors when several devices are in use. New session listing makes it easier to see what is active across simulator and Mac automation, while longer readiness waits improve reliability for apps that take more time to settle.

Better simulator and Mac Catalyst support

Simulator hardware-keyboard control is now available from the CLI, and simulator interactions are more dependable during boot and orientation changes. Mac Catalyst apps now launch through the same system path used by Xcode and Finder, fixing cases where an app built successfully but did not start correctly.

Also in this release

• Project and test discovery preserve valid platform information when a project contains an unfamiliar SDK root.

• Swift Testing summaries no longer misclassify a passing test when its display name contains a word such as “failed.”

• UI automation reports session mismatches more consistently instead of continuing with stale state.
