getting the same issue on XCode 16. tried with swiftui and uikit and got the same issue with the textfield lagging when tapped.

so i did some digging and it seems like the lag appears as a result of a bug in the xcode debug process, and as a result, running the app straight from my iphone doesnt produce the lagging bug. try it out yourself. manually close the app and then launch it straight from your device, you shouldn't get the lag again. it's not a complete solution but it should ease some anxiety, i know it did for me.
