undefined symbols:___ isplatformversionatleast

Question

I have used pod "SinchRTC" and I am able to build and run the project in debug mode. But now when I am achieving the project, I am getting the error :--

Undefined symbols for architecture arm64:
"___isPlatformVersionAtLeast", referenced from:
  -[RTCMTLRenderer setupTexturesForFrame:] in Sinch(libSinch-dist.a-arm64-master.o)
  -[RTCMTLVideoView frameRotation] in Sinch(libSinch-dist.a-arm64-master.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is this a framework issue because I am not getting any solutions?

I want to upload this build. Can you please provide me a solution for this.

Thanks in advance.

Which Xcode you are using to achieving? – sDev Feb 11 '20 at 05:44 — sDev, Feb 11 '20 at 05:44
Check it with Xcode 11 beta or later version. – sDev Feb 11 '20 at 07:25 — sDev, Feb 11 '20 at 07:25
Because isPlatformVersionAtLeast are in iOS SDK 13 – sDev Feb 11 '20 at 07:33 — sDev, Feb 11 '20 at 07:33

Make sure you have arm64 architecture turned on in your project's build settings. Also, if you are trying to use the same binary for both iPhone 5 and 6 (and others), make sure that and that 'Build for Active Architecture Only' is turned off.

Or

Try this

isPlatformVersionAtLeast are in iOS SDK 13, so would require Xcode 11 beta. I think you are getting the error because you are using an earlier Xcode version Xcode 10.3 .
