Please use the latest version of Xcode.

The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.

You will also need to install the Xcode Command Line Tools. Open Xcode, then choose Settings... (or Preferences...) from the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.

To install a simulator, open Xcode > Settings... (or Preferences...) and select the Platforms (or Components) tab. Select a simulator with the corresponding version of iOS you wish to use.

If you are using Xcode version 14.0 or greater than to install a simulator, open Xcode > Settings > Platforms tab, then click "+" icon and select iOS… option.

You will need to install CocoaPods with this comand:

brew install cocoapods

cd ios
bundle install
bundle exec pod install

Before launching the first comand, be shure to be at the root of the project (where package.json is installed).

npm start

npm run ios
