SwiftGen is a tool that automatically generates Swift code for all of the resources in your project allowing you to access them in a type-safe manner.īy examining our project's resources, SwiftGen can generate an enum that wraps those values and exposes them to the developer without the need for any force-unwrapping. Create and Upload an Asset Catalog File Give Einstein the images that can be selected as content assets in your messages. An easily overlooked line like this is a crash waiting to happen.įortunately, we can use SwiftGen to add a measure of type-safety to our approach. Over the course of developing a new feature, assets, fonts, colors, and images will be frequently entering and exiting your codebase. Now, imagine you’re on a team of developers that primarily focuses on product development work.
#Asset catalog creator crash how to#
From Studio Read the Creator Marketplace documentation to learn how to access and use these freely available assets in your experiences. In practice, however, this means that if the image doesn't exist - for whatever reason - this seemingly innocuous line will cause our app to crash. Access the Creator Marketplace Via a Browser Go to the Create page located in the top menu bar. These are the crash lines ive been getting: ACkeyboardcarcontrol. Var image = UImage(named: "image_name")! If you look at Swift projects on GitHub or code snippets on StackOverflow, you'll see examples of this behavior everywhere. Ive been getting multiple crashes everytime i try to load. From here, most implementations will simply force unwrap the response in order to get access to the UIImage directly: We know that when we try and access an image like UIImage(named:"image_name") that it returns an UIImage?. If you’ve ever written code like this in your iOS project, I'd like to introduce you to a developer tool that's going to make your life a lot easier and your code a whole lot safer.
