What can I do about it? I've seen another post that recommends downloading 14.5 from here and renaming the folder 14.7, but that does not work.
Does anyone have an idea on how to go about this?
The "iOS x SDK" means that you need to build your apps using the version of Xcode that includes support for iOS version x. (Apple releases versions of the iOS SDK as part of the Xcode IDE.) If Xcode 12 is the first version of Xcode that supports iOS 14, you need to build with Xcode 12.
Xcode doesn't support iOS 15.
Copy and paste the 14.5 directory into /Applications/Xcode. app/Contents/Developer/Platforms/iPhoneOS. platform/DeviceSupport . Make a duplicate of 14.5 directory by copy and pasting it into the same directory (into DeviceSupport ) then rename the directory to 14.6, 14.7, etc.
These OS versions also refuse debugger connections from older Xcode releases. Xcode 12 continues to support debugging for older OS versions, but without the new encryption. For debugging in iOS 14 devices you need Xcode 12 atleast.
New error message: Could not locate the device support files. Xcode could not determine the product version. If you are using a supported combination of Xcode and hardware, please reboot and unlock all devices (including the host mac), and respond to any outstanding pairing requests.
You can add support for iOS 14.5 (and watchOS 7.4) by copying the relevant DeviceSupport folders from Xcode 12.5 to Xcode 12.4. There are also publicly hosted GitHub repositories with these folders, a quick search will turn them up. It is obviously better to extract it from the official source yourself, but I think the archives are signed anyways.
After updating the iPhone to iOS 14.8 (18H17), the error message changed. New error message: Could not locate the device support files. Xcode could not determine the product version.
Updating to the latest beta of Xcode (Xcode 13 beta 3) worked.
Just not immediately. Left to buy some things, when I came back it worked.
i think you should connected you device, and wait xcode copy some suport file from device(will take several minutes). when successful will work fine.
