Salesforce retired the Swing Flow UI with the Summer ’19 release, and we recommend you migrate to Lightning Flow Builder. Since your organization currently uses that capability, we wanted to tell you how this impacts you and what your options are.
You’re also probably wondering why we’re retiring the Swing Flow UI. Salesforce wants to focus development on Lightning Flow Builder, which led us to the decision to retire this feature. The Lightning Flow Builder is a full-featured, web-based tool for creating screen-based and headless processes.
What changed?
After the Summer ’19 release, you can no longer run and/or edit/create Swing Flows. You should recreate your Swing Flows in Lightning Builder. Once you recreate your Swing Flows, deactivate and delete existing Swing Flows. You can find the Swing flows listed in the Flows list in Setup.
If no action is taken after the Summer ’19 release, the Swing-based flows will no longer run, and you will receive an error in the application logs.
What did you recommend?
We know that retiring a capability you’ve been using can be disruptive. To help guide you through this transition, we suggest you complete the Lightning Flow Trailhead Module and familiarize yourself with Lightning Flow Builder. Once you are familiar, recreate your Swing Flows with the Lightning Builder.
How can I get more information?
