1. Iphone 4s Simulator For Mac

Developers are doing
great things with Swift.

• Open the iPhone Simulator application. You can find the alias in Contents → Applications, as shown below. For easy access to the iOS simulator in the future, drag and drop the iOS Simulator alias on to your Desktop or the Applications folder. The iOS simulator is now installed and running on your Mac, as shown below.
• Simulator Launcher builds custom executables to automatically launch an embedded iPhone Simulator application using the correct iPhone SDK. To use, drag any iPhone Simulator binary onto the 'Simulator Builder' application. This will create a new Mac OS X application that bundles and launches your iPhone Simulator application from within Mac OS X.

You can't run iPhone apps on a Mac computer without using an emulator, though that will change with a new generation of Macs, set to come out by the end of 2020. The new Macs will run on Apple's.

Swift is a fast and efficient language that provides real-time feedback and can be seamlessly incorporated into existing Objective-C code. So developers are able to write safer, more reliable code, save time, and create even richer app experiences.

Great apps
built using Swift.

More and more developers are incorporating Swift code into their apps. And some are even building all-new apps entirely in Swift.

Better performance
equals better apps.

Swift apps more than live up to the name. For instance, a common search algorithm completes much faster using Swift.

10,000 integers found in a graph
using depth-first search algorithm*

Educators are adding Swift
to their curriculum.

Developers aren’t the only ones who’ve experienced the potential of Swift. Universities and academic institutions around the world teach with Swift and Xcode on Mac, empowering their students with the best tools to build amazing apps. And with Apple’s free Develop in Swift curriculum, the transition from introductory coding to app development with Swift has never been easier.

Colleges and universities that are incorporating Swift into their courses

• Aberystwyth University
• Borough of Manhattan
  Community College
• California Polytechnic State University
• Central Piedmont Community College
• Foothill College
• Full Sail University

• Houston Community College System
• Ingésup
• Lawson State Community College
• Mesa Community College
• Northwest Kansas Technical College
• Plymouth University

• RMIT University
• Southern Methodist University
• Stanford University
• Technical University of Munich
• Tecnológico de Monterrey
• University of California, Santa Cruz

Swift is everywhere.
And now it’s open for everyone.

Swift is free and open source, and it’s available to a wide audience of developers, educators, and students under the Apache 2.0 open source license. We’re providing binaries for macOS and Linux that can compile code for iOS, macOS, watchOS, tvOS, and Linux. And to help Swift grow into an even more powerful language, we created a community where users can contribute directly to the Swift source code.

Web developers know it’s important to test their websites on every web browser and device possible. And with the growing popularity of the iPhone, iPad, and iPod Touch, it’s only natural that they’ll also want to test their websites on all of those devices. But short of stocking up on a bunch of Apple products, how can developers preview their websites in iOS?

Actually, it’s easy. Anybody can do it by installing Apple’s iOS simulator on their Mac for free. This functional demo, complete with the mobile Safari web browser, allows you to preview your website or web application in iOS. It looks exactly the same as it does on an iPhone, iPad, or iPod Touch.

There are limitations to the simulator. You can’t install apps from the App Store in the simulator, so forget about playing Need for Speed: Most Wanted. And many of the apps that come preinstalled on iOS devices are not available in the simulator. Here’s the bottom line: This stripped-down simulator is great for testing websites, but not much else.

Installing the iOS Simulator on Your Mac

Ready to get started? The first step is downloading Xcode and installing the iOS simulator on your Mac. Here’s how to install the iOS simulator on your Mac:

1. Download and install Xcode from the Mac App Store. It’s free!

2. Right click on the Xcode icon in the Applications folder and select Show Package Contents, as shown below.

3. Open the iPhone Simulator application. You can find the alias in Contents → Applications, as shown below.

4. For easy access to the iOS simulator in the future, drag and drop the iOS Simulator alias on to your Desktop or the Applications folder.

5. The iOS simulator is now installed and running on your Mac, as shown below.

As mentioned earlier, you’ll notice that the simulator is missing a lot of the applications and settings that come with every iOS device.

Rotating the Simulator

Every iOS device has a gyroscope that keeps track of the screen’s orientation. For example, if you turn the device horizontally, iOS will automatically rotate the screen if you’re using an app that supports the feature. The simulator can rotate, too! It can be a useful tool when you’re developing a responsive website or web app.

Here’s how to rotate the simulator:

1. Open the iOS simulator, if it’s not already open.

2. Open the Safari app in the simulator.

3. From the Hardware menu, select Rotate Left or Rotate Right. The simulator will rotate, as shown below.

To rotate the simulator back again, select a rotation option from the Hardware menu.

Simulating Different iOS Devices

What good would an iOS simulator be without the ability to switch between the different dimensions of the iPhone 4, iPhone 5, and the different versions of the iPad? The simulator lets you use them all on your Mac. Here’s how to simulate a different iOS device with the iOS simulator:

1. Open the iOS simulator, if it’s not already open.
2. From the Hardware menu, select Device, and then select the type of device you want to simulate.
3. The simulator window will change to match the dimensions of the device you selected.

To restore the original window with the iPhone case as a border, select iPhone.
