How to install the simulator on Xcode
1. After downloading xcode, open and create a new project
2. Select app
4. Just enter a project name and click Next in the lower right corner
6. Choose the version of the ios system you need. What I need is the ios 11.1 system version. The memory is relatively large, and the download may take a long time. I downloaded it 3 times, and the first 2 times were due to network interruption. It is best for everyone to download before Ensure the smooth flow of the network.
7. If you don't really want to develop ios, you can use the following method to open the simulator. (I am testing the compatibility and incompatibility of the front-end page on the simulator, and I do not do ios development)
Then the simulator runs
