手动安装watchOS 9.1 Simulator Runtim

Download the Simulator runtime you want to install from the developer website. Then follow these steps with the command line to install it:

1. Select the version of Xcode for installation.

2. Run the first launch experience to install the required system components, including simctl.

3. Install the Simulator runtime with simctl.

For example:

sudo xcode-select -s ~/Applications/Xcode.app 

xcodebuild -runFirstLaunch    

xcrun simctl runtime add "~/Downloads/watchOS_9.1_Simulator_Runtime"

simctl verifies the signature of the downloaded Simulator runtime, and then installs it in a secure location on your computer.
