Cases when Swift does not work

1. Limited Platform Support: Swift is primarily designed for Apple platforms such as iOS, macOS, watchOS, and tvOS. Therefore, it may not be suitable for projects targeting other platforms like Windows or Android.
2. Legacy Code Integration: Swift is a relatively new programming language, and it may not seamlessly integrate with older codebases written in languages like Objective-C or C++. This can be a significant challenge when working on projects that require the integration of legacy code.
3. Performance-intensive Applications: While Swift is known for its speed and efficiency, there are cases where other programming languages like C++ or Rust might outperform it in highly performance-intensive applications. For scenarios that demand the utmost optimization, Swift may not always be the optimal choice.
4. Limited Third-Party Library Support: Although Swift has a growing ecosystem of libraries and frameworks, it still lacks the vast array of third-party libraries available for more established languages like Java or Python. This can be a drawback when working on projects that heavily rely on existing libraries.
5. Cross-Platform Development: If you are developing an application that needs to run on multiple platforms, Swift may not be the most suitable option. While frameworks like SwiftUI and Kotlin Multiplatform allow code sharing across platforms, they are still relatively new and come with their own set of limitations.
