Install iOS12 simulator on Xcode 9

Question

Im running Xcode 9.2, updating to Xcode 10 means a huge update to my codebase, not quite ready for that. I need to run a simulator with iOS 12 capabilities. Is this possible?

Answer 1

Sort of:

• Download Xcode 10 from here (You can download it from Appstore but be sure to back up the Xcode 9 first and do not replace it)
• Run Xcode 9
• Build your project (command + B)
• Run Xcode 10 with new project
• Run iOS 12 simulator
• Open your project in any Xcode version you want
• Drag the project target file (myProject.app) into the simulator.
• Click on your app icon

This method prevents your codebase from those huge update.
