I am using MacOS 26.1 and Xcode 26.1; my existing project cannot select a simulator, but creating a new project allows me to select a simulator normally.
No simulators on Xcode 26.1
Hello,
Could you check your project current minimum deployment?
Xcode 26 supports targeting devices and simulators for
- iOS 15 or later
- tvOS 15 or later
- watchOS 8 or later
- visionOS 1 or later
May I ask, if the simulator upgraded from an older Xcode version can be used normally, but if using a new device and a new Xcode, do we have to configure the environment according to the minimum requirements?
Check your Xcode -> Settings -> Components.
iOS should be installed
The newly created project can normally choose to use the simulator, while the existing old project cannot.
