How to Use Objective C Static Library in App Target?

When developing iOS applications, you often come across a situation where you need to integrate an existing Objective-C static library into your app target. In this article, we will explore the steps involved in using an Objective-C static library in an app target.

Case 5: How to Use Swift Static Library in App Target?

In addition to integrating Objective-C libraries, you may also want to use a Swift static library in your app target. This is possible by following similar steps as above.

Case 4: Create a Objective C Static Library

Before we dive into using an existing library, let's first create a simple Objective-C static library. In this example, we will create a basic math library that provides addition and subtraction functions.

In some cases, you may want to use your Swift code in an Objective-C class. This can be achieved by creating a Swift static library and importing it into your Objective-C project.

Case 2: Swift and Objective C code resides in same App Target

One of the most common scenarios is when both Swift and Objective-C code reside in the same app target. In this case, you will need to use bridging headers to access the translated signatures.

Should You Use Objective- C Or/and Swift?

When deciding whether to use Objective-C or Swift, consider the following factors: performance, compatibility, and maintainability. While Swift is a more modern and efficient language, Objective-C has its own strengths when it comes to legacy code integration.

Swift Objective C Interoperability, Static Libraries, Modulemap etc…

To ensure seamless interoperability between Swift and Objective-C, you will need to use bridging headers to access the translated signatures. Additionally, you can also manually create a bridging header file by creating an Objective-C header file and importing it into your project.

Should You Migrate Objective- C Code To Swift?

In some cases, migrating your existing Objective-C code to Swift may be beneficial for improved performance and maintainability. However, this decision ultimately depends on the specific requirements of your project.

By following these steps and understanding the concepts involved in using an Objective-C static library in an app target, you can successfully integrate your libraries and take advantage of the best features of both languages.

In conclusion, using an Objective-C static library in an app target is a straightforward process that requires minimal effort. By following the above-mentioned steps and understanding the concepts involved, you can seamlessly integrate your libraries and take advantage of the benefits offered by both Swift and Objective-C.
