Changing the Thumbnail of an App in Swift Playgrounds
By the end of this tutorial, you will be able to change the thumbnail of an App project in Swift Playgrounds for iPad.
Since the latest update to the Swift Playgrounds app for iPad it is possible to create App projects using it, enabling you to develop and publish iOS applications even without Xcode.
The thumbnail of the project on your playgrounds gallery is based on your app icon and the accent color of your application, and it is automatically generated by Swift Playgrounds.
And even if you upload a custom icon to your application, the thumbnail will still be automatically generated, but using your custom image instead of one of the predefined placeholder icons you can choose from.
Recently Apple has released a series of sample apps on their tutorials portal and all those apps became available to be downloaded at the new App Gallery section of the Swift Playgrounds app on the iPad.
You might have noticed that the thumbnails of the sample apps provided by Apple are not the thumbnail that is automatically generated by Swift Playgrounds, but a custom image, even though there is no way to change the thumbnail of the project using the interface of Swift Playgrounds or even opening the project on Xcode.
So, how can we change the thumbnail of our app project on Swift Playgrounds?
