module compiled with Swift 4.1 cannot be imported by the Swift 5.3.1

[harshTechEfficio]

I'm getting below error, when I have added webexsdk using pods and run the application. "module compiled with Swift 4.1 cannot be imported by the Swift 5.3.1" I have checked it in Xcode 12.2 and 12.4

Sometimes the error says The following binaries use incompatible versions of Swift /Users/XXXXXX/Frameworks/Sbu.framework/Sbu

I have tried the below things.

• Deleting Derived Data.
• Checked if Command-line tools are correct.
• Deleting pod.lock file
• Updating Pods
• Changing scheme to WebexSDK and building project, changing back to project scheme and building it.
• Enabled "Build libraries for distribution" in build setting.

Kindly help me in solving the issue.

can you try to switch the command line tool?

@harshTechEfficio did you resolve this issue?

[harshTechEfficio]

I only have one XCode version and my Command Line Tools is pointed out to the correct version. I still get the same error. "module compiled with Swift 4.1 cannot be imported by the Swift 5.3.1"

Are you using our example project? @harshTechEfficio

[MrShiY]

or you can try to change swift version of SDK.

In the example project, the SDK is working fine. I'm using pods to add the framework to my project. When I add it to my project it is throwing me an error.

@harshTechEfficio Can you match your project setting with example project setting? I think WebexSDK is fine, may be due to project setting.

Or can you try to create a new project and pod install WebexSDK ?
