I am trying to set up a react-native development environment. I would like to set up an iOS emulator (preferably an iPhone 10) to run my app on. I am using a Macbook Pro 2016 running on MacOS 10.14.3. I have installed my react-native app through the command create-react-native-app (running version 2.0.2). I also have installed XCode running version 10.2(10E125). When I scan the QR code that Expo generates and run it on my iPad or my Android device it works just fine, but when I try to load the iOS emulator by pressing i after expo start it returns the error
Trying to open the project in iOS simulator...
Simulator is installed but is identified as 'com.apple.CoreSimulator.SimulatorTrampoline'; don't know what that is.
Simulator not installed. Please visit https://developer.apple.com/xcode/download/ to download Xcode and the iOS simulator. If you already have the latest version of Xcode installed, you may have to run the command `sudo xcode-select -s /Applications/Xcode.app`
I have already tried running the command sudo xcode-select -s /Applications/Xcode.app
I have also tried running the command xcode-select -r
I have also confirmed that in my XCode->Preferences->Locations Command Line Tools is selected as "Xcode 10.2(10E125)"
None of these have worked.
I am expecting that after pressing i after expo start an iOS emulator loads up. Thank you.
-----EDIT-------
After some more research, I found out that running open -a Simulator and then running expo start loads the app on an emulator and works for my purposes. But still if I just run expo start without running open -a Simulator it still gives the same error. I want to ask if this is the best I am going to get?
