Starting April 2021, all iOS and iPadOS Apps submitted to the App Store must be built with Xcode 12 and the iOS 14 SDK. Tuya OEM App has been adapted to Xcode12 in the template v3.24.6 and above (please contact Tuya PM for coordination as soon as possible for custom branches), and it is recommended to use the latest template to build and launch it (Apps that launch before April will not be affected);
Starting from April, templates prior to OEM v3.24.6 will not be able to be released to the App Store. Please make reasonable arrangements in advance. Thank you for your support to Tuya!
