You need to copy and paste the DevImg file 16.0 and rename it to 16.1.
THe DevImg (Developer disk for IOS) needs to match the verison on your IOS device.
By default you can find the Developer disks in the installation folder (contents) of xcode:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport```
The logic is the following:
In case your IOS version is not existing as a folder you need to copy and paste the “previous versions folder”
In your case: you want 16.1 but only have 16.0. e.g. for 16.6 you need to copy and paste 16.4 and rename it to 16.6
copy and paste 16.0 and rename it to 16.1 (as you can see below)
Make sure the developer Disk is present in the folder you defined in the EPF Connection.
The developer disk list is based on the xcode version you have installed.
Hope this is helpful . Let me know in case you have further questions.
Cheers.,
