How to Resolve Camera Cannot Open in PWA Using Dynamsoft Barcode Reader on iOS

❓ Issue

When using Dynamsoft Barcode Reader in a Progressive Web App (PWA) on iOS, the camera fails to open. This prevents barcode scanning functionality from working as expected.

💡 Cause

This issue is due to limited PWA support on iOS. Specifically:

• iOS has known restrictions when accessing camera features from PWAs.
• Cached data or system-level inconsistencies can cause the camera initialization to fail.

✅ Solution

To resolve the issue:

1. Clear Safari cache(iOS 18+):
   • Go to Settings > Apps > Safari > Clear History and Website Data.
2. Reboot the device:
   • Power off your iPhone or iPad completely, then restart it.

After following these steps, try launching the PWA again and accessing the camera.

📌 Note

This issue is specific to iOS PWAs. On Android or desktop browsers, Dynamsoft Barcode Reader in a PWA generally works without issue.
