• Open Finder.
• Use Cmd + Shift + G to bring up the "Go to Folder" dialog.
• Enter the following path and press Enter:

~/Library/Developer/Xcode/iOS DeviceSupport/

2. Find the Problematic Folder and Delete it
Inside the iOS DeviceSupport directory, you’ll see subfolders corresponding to different iOS versions from your connected devices. Locate the folder that matches your iPhone’s iOS version.
