iOS 4.18.0 introduces new JWCaptionStyle features, improves player setup performance, and addresses numerous bug fixes, enhancing playback stability and UI consistency.

New Features

• Developers can explicitly set backgroundOpacity, textOpacity, and fontSize through the JWCaptionStyle.
• Developers can use a new .overrideStrategy(_:) method on JWCaptionStyleBuilder to override the user’s device settings to meet specific business needs or use cases.
• Player setup performance has been improved to decrease the likelihood that the HLS algorithm selects the lowest-quality stream.

Bug Fixes

• The didReceiveAccessLogMetadata access log entry delegate method fires as expected.
• Navigating away during the player setup no longer causes a crash.
• Fast-forward and rewind controls are now available in Picture-in-Picture mode for DAI VOD assets.
