Xcode Version 13.2.1 - install ios 18 and ios 17.5

I created an application in xcode 13, and I need to install it on my iPhone 12 iOS 18. I already went to the Apple Developers website and downloaded the files iOS_17.5_Simulator_Runtime.dmg and also the file iOS_18_beta_Simulator_Runtime.dmg

I copied them to the folder on my Mac /Library/Developer/CoreSimulator/Profiles/Runtimes/

And even so, when I opened xcode and went to deployment info, the most recent iOS version is still 15.2 and the last one I downloaded doesn't appear.

what should I do ?

I preferably want to install iOS 18 beta on my iPhone 12
