How to determine the current iPhone/device model?

📱 How to Determine the Current iPhone/Device Model? 🤔

Are you wondering how to find out the model of your iPhone or device while developing your app in Swift? 🤷‍♂️ Fear not, we've got you covered! In this post, we'll explore how to determine the current iPhone or device model using Swift. 🚀

The Issue 🔄

Let's start with the context: the built-in UIDevice.currentDevice().model property in Swift only returns the device type (iPod touch, iPhone, iPad, iPhone Simulator, etc). 😕 So how can we get the specific model name, such as iPhone 4S, iPhone 5, iPhone 5S, and so on? 🤔

The Objective-C Solution ✅

Before we dive into the Swift equivalent, let's quickly look at how this can be easily achieved in Objective-C. 🕺

By importing the <sys/utsname.h> framework and using the uname(&systemInfo) function, we can store the device model name in the systemInfo structure. Finally, by converting the systemInfo.machine to an NSString, we get the desired device model. Voila! 🎉

#import <sys/utsname.h>

struct utsname systemInfo;
uname(&systemInfo);

NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
                          encoding:NSUTF8StringEncoding];

The Objective-C solution is straightforward, but what about Swift? 🤔

The Swift Solution 🌟

In Swift, we can use the sysctlbyname function from the <unistd.h> framework to retrieve the device model name. Let's break it down step by step! 💡

1. First, import the <sys/utsname.h> framework:

import sys/utsname

1. Declare the uname function:

func uname(_ arg: UnsafeMutablePointer<utsname>) -> Int32

1. Create a structure to hold the system information:

var systemInfo = utsname()

1. Call the uname function and provide a pointer to the systemInfo structure:

uname(&systemInfo)

1. Retrieve the device model name stored in systemInfo.machine and convert it to a String:

let deviceModel = withUnsafePointer(to: &systemInfo.machine) { ptr in
    ptr.withMemoryRebound(to: CChar.self, capacity: 1) { ptr2 in
        String(cString: ptr2)
    }
}

And that's it! Now you have the device model name stored in the deviceModel variable. 🎉

Example Usage 💪

To see the solution in action, let's modify the original UIDevice.currentDevice().model to our new Swift solution:

import UIKit
import sys/utsname

var systemInfo = utsname()
uname(&systemInfo)

let deviceModel = withUnsafePointer(to: &systemInfo.machine) { ptr in
    ptr.withMemoryRebound(to: CChar.self, capacity: 1) { ptr2 in
        String(cString: ptr2)
    }
}

print(deviceModel)

When you run this code, you'll see the device model name printed in the console. 🖥️

Your Turn! ✏️

Now it's your chance to put this solution into practice! Use the code we just provided to retrieve the device model name in your own app. 📱

Wrapping Up 🎁

Determining the current iPhone or device model using Swift is no longer a mystery! By following the steps outlined in this post, you can now easily retrieve the specific device model name. 🙌

Remember, understanding your device's model can help you optimize your app for different devices and provide a better user experience. 🚀
