I'm experiencing an issue here on my Xcode 16.4, where i can't download the supported iOS 18.6 runtime because it stays stuck on the 'preparing' state. I have also tried getting it manually from the dev site but they only have 18.2. The only runtime that would download easily via Xcode was 17.5 but I can't build my project with that. I have tried using curl to even get a download url, nothing worked. All my terminal approach didn't work also.
Any help or guidance to sort this out? Thank you.
