Effortlessly Generate App Store Screenshots Fast!

Updated: Dec 5, 2023

In a previous blog post, 'Dream, Create, Impact: Navigating the Journey from App Creation to App Store', I highlighted the laborious nature of the steps required to craft screenshots that align with the exacting specifications of the Apple App Store. These screenshots serve as the gateway to getting your app into the hands of users. Without them, your app cannot be submitted to the App Store, and your creation remains out of reach. However, in this blog post, I'm thrilled to introduce an elegant solution that can transform what used to be a potentially hours-long ordeal, or demand the need for a design team, into a matter of mere seconds for any developer.

The Challenge

In the dynamic world of app development, the significance of crafting flawless screenshots cannot be overstated. These visuals play a pivotal role in getting your app released on the App Store, enticing users to download your app and form their first impression. Yet, the path to achieving this perfection is anything but straightforward, especially when adhering to Apple's stringent specifications for a plethora of devices, ranging from iPhones to iPads.

For developers, this can feel like a daunting challenge, involving a complex journey filled with intricacies. The quest for or creation of suitable device frame graphics, the intricate dance with diverse design tools to piece together the final composite image, and the meticulous management of pixel-perfect image sizes and file formats all contribute to the complex choreography.

As someone with a background in graphic design, I could create these images myself, but even for me, the process wasn't swift. Realizing the need for a solution that caters to developers without a design background, I scoured the internet in search of tools to streamline this laborious task. My quest led me to, which, while helpful, still demanded more effort than I'd hoped for. But there was a shining beacon on the horizon, an online resource that seemed to be a step closer to my dream solution –

Yet, even with these discoveries, I was far from satisfied. The time-consuming aspects persisted. The struggle to pinpoint the exact device frame I required continued, and the often mediocre design tool interfaces didn't make things any easier. I still had to grapple with the creation of specific image sizes and navigate through multiple download steps. Furthermore, some resources imposed a price, be it through subscription fees or attribution requirements. As a creator, I wholeheartedly support such initiatives, but they undeniably added an extra layer of complexity to the process.

The Solution

The answer to this challenge comes in the form of a streamlined and efficient process that any developer, with the use of Xcode and the command line, can use. Behind the scenes, I have created the necessary graphic files and command line script to allow this efficient process to come to life. By following the steps outlined below and having a few essential tools at your disposal, you can save valuable time and effortlessly create App Store screenshots.

  1. Set Up Your Xcode Environment: Start by building the required device simulators in Xcode. In my case, an iPhone 14 Plus simulator was built, to meet the App Store iPhone 6.5" Display req. This step ensures that you have a faithful representation of the target device for your app screenshots.

  2. Save Files On Your Machine And Update Script Paths: Two files I have created are essential: a background file and a device frame file that the script will use to create the final composite App Store image. Edit the script in the necessary locations to reference the paths to these two files on your machine.

  3. Run The Script: The key to this solution lies in running a script, which simplifies the entire process. The script automates the task of taking a screenshot from your simulator, overlaying a device frame, and saving the image to the proper size for upload to the App Store.

  4. Upload To The App Store: Once the script has done its job, you're left with a perfectly crafted screenshot that meets all of Apple's specifications. It's now ready to be uploaded to the App Store, eliminating the need for third-party tools, multiple downloads, or any attribution requirements.

With this solution in place, the process for creating App Store screenshots becomes a breeze. Not only is it more efficient, but it also empowers developers to create the perfect visuals without the hassle of managing multiple tools and steps or relying on a team of designers.

Required Screenshots and Image Specifications

  • iPhone 6.5" Display - 1242 x 2688 pixels

  • iPhone 5.5" Display - 1242 x 2688 pixels

  • iPad Pro (6th Gen) 12.9" Display - 2048 x 2732 pixels

  • iPad Pro (2nd Gen) 12.9" Display - 2048 x 2732 pixels

Future Enhancements

The great thing about this solution is its flexibility. In true agile fashion, I currently focused on manually booting only one simulator from Xcode and creating only one required image for the App Store, but there are plans to enhance the script further. In the future, this script will hopefully be able to boot all necessary simulators and create all four required images with the running of one script. This medium post, 'simctl: Control iOS Simulators from Command Line' has been and will continue to be a big help.


In the fast-paced world of app development, efficiency and agility are crucial. Designing screenshots for the App Store should not be a cumbersome task, and with the Xcode script solution, it no longer has to be. By building the required device simulator, running the script, and uploading the image to the App Store, developers can streamline their graphic design process and get back to what they do best - building apps. So, if you've been struggling with the challenge of App Store screenshots, it's time to embrace this innovative solution and make your life as a developer easier and more enjoyable. If this solution piques your interest, don't hesitate to get in touch with me here. I'll be more than happy to provide you with the essential files that can turn the dream of creating App Store screenshots in seconds into a reality!
