Well, The Scheme chooser had only one option to install Xcode 26 support. I downloaded the 8GB installer for it. Afterwards I have gotten back all my old choices of supported Devices/IOSVersions . So this is fixed.

Well , you are close. It was the Devices tab. So you got me to throw more darts. Within Devices tab Clicking on the device and going into detail screen it shows a Disable button. I Disabled the devices then the device still appears in the list. I then re-enabled the device. Now restarted Xcode and the problem went away. I'll show screen shot of the problem and the device screen to disable/re-enable. Thanks you very much !

I have this same problem. It all started last night when a replacement phone arrived from Verizon. Verizon had me re-use the sim Card. Now Xcode won't build for this device. Anyone have a good way to fix this??? I have repaired the device. Reset the devices . On portal, I reset the devices under Certificates, Identifiers and profiles. It also says myProj.xcodeproj Provisioning profile "iOS Team Provisioning Profile: tafam.com.Y" doesn't include the currently selected device "iPhoneXSMax" (identifier 00008020-0019289C2E02003A).

I guess not many people are clamoring for this answer. Alas, I too have the same problem. My Health exercise iOS app on apple desktop silicon goes dark with the screen saver. It is hard to do any health exercises when the screen saver kicks in. It works just fine on the iOS devices.

I have this same problem. Accessing the section crashes.     override func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {         if indexPath.count != 2 {             print( indexPath.debugDescription )             print( indexPath.description )             print("hi")         } // Outputs // [] // [] // Then crashes         let row = indexPath.section == 0 ? indexPath.row : indexPath.row + 2

Geesh , Where are the Apple Developers ? Don't they ever read these and step up ?
