Two days after releasing iOS 12.3, Apple has today seeded the iOS 12.4 developer beta for iPhone, iPad and iPod touch. The new beta is now available for download on all iOS 12 compatible devices. If you are a developer with beta configuration profile installed on your device, then head over to Software Update section of your iOS device to install the latest beta.
