The "File is universal but does not contain an ARMv7s slice" Error: How to Bypass and Add Support to External Static Libraries on iOS

So, you've just upgraded 🆙 to the latest version of 🔧Xcode🔧 and you're excited to dive into your project. But wait, what's this? You encounter an error message that goes something like:

ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /file/location for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation)

Uh-oh! 😱 What does this error mean? And more importantly, how can you bypass it and add support to the library if the library's developer hasn't updated it yet? 🤔

Don't worry, we've got you covered! In this guide, we'll walk you through the common issues surrounding this error and provide you with easy solutions to bypass this obstacle on iOS. 🚀

Understanding the Error

To be able to effectively overcome this error, it's important to understand its cause. When you see the "file is universal but does not contain an ARMv7s slice" error, it means that the static library you're trying to use doesn't support the ARMv7s architecture – one of the architectures targeted by iOS devices.

Solution: Use Build Options

Now, you may be wondering, is there any way to work around this error and still use the library? The answer is yes! 💪 Here's what you can do:

1. Open your project in 🔧Xcode🔧.

2. Go to your project's Build Settings.

3. Scroll down to find the Architectures section.

4. Click on the Architectures option to expand its settings.

5. Look for the Valid Architectures field.

6. Double-click on the Valid Architectures field to edit its value.

7. Remove armv7s from the list of architectures.

8. Save your changes.

By removing the armv7s architecture from the list of valid architectures, you're essentially allowing your project to be built without targeting that specific architecture. This bypasses the error and still allows you to utilize the library in question. 🎉

Getting the Library Updated

While the above solution provides a workaround, it's important to note that it's only a temporary measure. To ensure the best compatibility and performance, it's preferable to have the library updated by its developer to include support for the ARMv7s architecture.

To help expedite the process, consider reaching out to the library's developer and kindly request an update that includes support for the ARMv7s architecture. If possible, provide them with detailed information about the error you encountered and the benefits of supporting the ARMv7s architecture.

Engage with the Community!

Now that you have a solution and understand the importance of getting the library updated, it's time to engage with the iOS developer community! Share your experience, tips, and questions on forums, social media platforms, and developer communities. 🌐
