Swifty Compiler is specifically designed for developers who want to practice Swift programming and test code snippets directly from their iOS devices. The app creates a functional Swift environment that runs code on Linux servers, making it possible to write and test standard Swift logic anywhere. This approach allows users to refine algorithms, practice syntax, and work on command-line tools while commuting or during spare moments.
Key features include syntax highlighting, code completion, and the ability to import FoundationNetworking for basic networking tasks. The app also includes OCR functionality that can convert handwritten code or screenshots into executable Swift code, which is particularly useful for capturing ideas quickly. However, users should note that Apple's proprietary frameworks like SwiftUI and UIKit aren't available due to iOS sandboxing restrictions. The requirement for an internet connection to execute code might also limit usage in offline scenarios.
User reviews consistently praise the app's interface and its effectiveness for learning Swift fundamentals. Several users mention using it during commutes or coffee breaks to stay sharp with Swift syntax. The premium version adds additional font options and advanced features that appeal to serious learners. While not suitable for full iOS app development, it serves its intended purpose well for coding practice and logic refinement.

Sometimes I just want to jot some code down on a napkin to write out an idea and this takes it to another level. The OCR and screenshots are the cherry on top for me!
