While working with the cross-platform frameworks like React Native, we do not need to build our app every time to test our code on a simulator or real device. It is obvious to open the simulator before we can test the app on the simulator. The common approach to open a simulator can be to start a new build from the Android Studio or the Xcode. It works very well. But it may become frustrating sometimes when you want the things to happen very quickly but the build is taking a long time to open the simulator and test the app. Today, we will be creating some bash scripts to automate the process and start our simulators by just double clicking on the bash script files without creating a new build every time we start working on a code.

2-Step process to Launch iOS Simulator for Mac Device without XCode Step 1: Head to the Spotlight Search (cmd + space) and type “Simulator” to launch the default simulator. As an alternative to this, you can also go to the Applications tab present in the finder Window and then select Simulator from the list of available applications.

• Well, that’s not entirely true, you can actually still directly launch iOS Simulator without opening Xcode first by creating an alias. Note that modern versions of Xcode and OS X call the iOS Simulator simply “Simulator”, where you go will depend on which version of OS X the Mac is running.
• From Xcode, launch the iOS simulator: 3. Verify that the desired device is selected, in this case I am using the iPhone 7 device as shown below. If the App that you plan to install is already installed, you should delete it. Then proceed with installing the updated release.

The below scripts are tested only for MacOS.

iOS

1. List the installed simulators

First, we will check the device id for the simulator which we want to start. Hit below command to list all of the installed iOS simulators:

The output will be like:

Choose the ID for the simulator of your choice from the above list. For example, B8GFGPCF-CA22-4932-85H2-CA2980351D31 for iPhone 11.

2. Create the bash script

Create a bash file with a name of your choice, e.g. start_iphone11.sh:

and add the following content in this file(by replacing with the simulator id):

In our example, for iPhone 11, the content will be like:

It will boot the simulator app and open the simulator with the selected device.

Android

1. List the installed emulators

Hit below command to list all of the installed android emulators(assuming that you have already installed some emulators in Android Studio’s AVD Manager):

It will list the name of all of the installed emulators like:

2. Create the bash script

Create a new bash file with a name of your choice, e.g. start_pixel_2.sh:

and add the following content in this file(by replacing with the emulator name):

In our example, for Pixel 2, the content of the file will be like:

Making the scripts executable

Now, our next step will be to make these bash scripts to be executable by double tapping on them. In order to do so, hit the following commands in the terminal inside the same file directory as that of the bash files:

That's it.

Running the simulators

When you execute these scripts(for example, by double tapping on them), your simulators will be up and running within 2 minutes.
