I am currently using Xcode 16 (16A242d) and testing on an iPhone 7 running iOS 12.1.3. However, when I try to launch the app on the device, it crashes immediately. Below are the crash logs from the iPhone 7: 错误 11:54:55.731858+0800 kernel Sandbox: assertiond(62) System Policy: deny(1) file-read-metadata /private/var/mobile/Library/DuetExpertCenter/caches/ATXCacheFile-_ATXAppPredictor-TotalScore 错误 11:54:55.731897+0800 kernel Sandbox: assertiond(62) System Policy: deny(1) file-read-metadata /private/var/mobile/Library/DuetExpertCenter/caches 错误 11:54:55.754498+0800 kernel Sandbox: duetexpertd(132) deny(1) mach-lookup com.apple.proactive.ActionPrediction.predictions 错误 11:54:55.756102+0800 duetexpertd Unable to remove recent engagement cache file.

Even after archiving and installing the app, it still crashes. According to the official documentation, Xcode 16 is supposed to support iOS 12, but this issue persists. I would like to know the possible reasons for this behavior.

I ran into a problem. When using Storekit1 to purchase an SKU, the user payment was successful, but StoreKit1 did return paymentCancelled to my App. I would like to know under what circumstances this problem may occur? How do I fix it? Thank you

Dear all, For an important client, we are currently experiencing issues related to performance IOS build using Xcode Cloud. More in detail, their build process is taking approximately 30 minutes to complete at the moment, whereas the same build executed locally on a Mac machine takes around 7 minutes. This significant difference in build times is causing concerns and slowing down the development work. We would appreciate your support in identifying possible causes and exploring different ways to improve the actual situation (ex if it is possible to increase the Cloud machine calculation power). Could you please advise us on how we might proceed to analyze and potentially optimize the build times on Xcode Cloud? What kind of processors are used? Any guidance, best practices, or diagnostic steps you can suggest would be greatly appreciated. Looking forward to your support.

My version is iOS 18.6.2 (22G100), watchOS 10.6.1 (21U580), macOS 15.3.1 (24D70), Xcode Version 16.4 (16F6). My iPhone can connect to Xcode and complete app installation testing. I have connected the iPhone to Xcode via USB, and both the iPhone and Apple Watch have been set to trust this device. The iPhone has Developer Mode enabled, but I cannot find Developer Mode in the Privacy & Security settings on the Apple Watch. As shown in the image, the Devices section in Xcode's Developer Documentation displays my iPhone but not the Apple Watch. However, the Open Console for the displayed iPhone shows my Apple Watch—actually two of them, though I only have one Apple Watch (the other might be from a previous backup). The iPhone app installs and tests normally, but the Apple Watch app cannot select a target device and fails to start installation. How can I resolve this issue?
