[Solved] SwiftUI Previews not working after installing iOS 17 Simulator – Swiftui

The Problem:

After installing the iOS 17 simulator, users are unable to use the SwiftUI preview canvas. The canvas perpetually displays a spinner instead of rendering the interface. This issue affects both new and existing projects. The user is using Xcode 15.0 and macOS 13.5.2. Despite attempts to resolve the issue, it persists. Assistance is sought to diagnose and rectify the problem.

The Solutions:

Solution 1: Update iOS Simulator

1. Verify iOS Simulator Version:

• Open the Xcode project where SwiftUI previews are not working.
• Click on the "Simulator" menu in the Xcode toolbar.
• Select "Simulator" from the dropdown menu.
• Check the version of iOS Simulator you are currently using.

2. Update iOS Simulator:

• If you are using an iOS Simulator version prior to 17.0.1, you will need to update it.
• Click on the "Simulator" menu in the Xcode toolbar.
• Select "Update Simulator" from the dropdown menu.
• Follow the on-screen instructions to install the latest version of iOS Simulator.

3. Restart Xcode:

• Once the iOS Simulator update is complete, restart Xcode.
• This will ensure that Xcode is using the updated version of the simulator for SwiftUI previews.

4. Check SwiftUI Previews:

• Open the SwiftUI preview canvas in Xcode.
• If the previews are still not working, try restarting Xcode again.
• The SwiftUI previews should now work correctly with iOS Simulator version 17.0.1 or later.

Additional Tips:

• Make sure that you are using the latest version of Xcode.
• Ensure that your Xcode project is targeting the correct iOS version.
• If you are still experiencing issues with SwiftUI previews, try cleaning the build folder and rebuilding the project.
• Check the Xcode console for any error messages related to SwiftUI previews.

Solution 2: Change the simulator preview

If you are experiencing issues with SwiftUI previews not working after installing the iOS 17 Simulator, changing the simulator preview might resolve the issue. Here are the steps to do that:

1. Open the Xcode project where you are experiencing the problem.
2. Click on the “Simulator” menu item at the top of the Xcode window.
3. Select “Choose Simulator…” from the drop-down menu.
4. In the “Simulator” dialog box that appears, select a different simulator device from the list.
5. Click on the “Launch” button to launch the simulator with the selected device.
6. Once the simulator is launched, try running the SwiftUI preview again. It should now work properly.

By changing the simulator preview, you are essentially resetting the preview environment, which can sometimes resolve issues with SwiftUI previews not working properly.
