Can existing Objective C apps be migrated to Swift?
Yes, it is possible to migrate existing Objective C apps to Swift. Swift is designed to be interoperable with Objective C, allowing you to gradually introduce Swift code into your existing Objective C project. Migrating to Swift brings several advantages, including improved performance, safety, and readability. However, the process of migrating can be complex and time-consuming, requiring careful planning and testing. It is recommended to start by identifying the key components that need to be migrated and creating a clear migration plan. Then, you can begin by converting classes, functions, and frameworks one by one and gradually replace Objective C code with Swift code. Testing is crucial throughout the process to ensure that the functionality remains intact and there are no regressions or compatibility issues.
