Previous preparation error: Developer Mode disabled; To use <My-Device-Name> for development, enable Developer Mode in Settings → Privacy & Security.

I am getting this error even after I enabled developer mode in my device. I'm running 15.1 Sequoia Beta and the latest iOS 18 beta.

I've tried reinstalling xcode, clearing derived data, forgetting and re-pairing the device, but nothing works.

Tried with a few other devices as well, but to no luck. Kindly help as this is really interfering with my developement.

UPDATE: Doesn't work with Xcode 16 Beta 4, 16 Beta 5, 16.1 Beta.

I have the sam issue. But I can't find a way to fix it.
