Facing issue integrating the ACSUICalling library to my project

Question

i am trying to integrate ACS to my app and facing this issue

Failed to build module 'AzureCommunicationCalling'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.6 (swiftlang-5.6.0.323.62 clang-1316.0.20.8)', while this compiler is 'Apple Swift version 5.7.1 (swiftlang-5.7.1.135.3 clang-1400.0.29.51)'). Please select a toolchain which matches the SDK.

it is working fine with another project

i tried adding 'AzureCommunicationUICalling', '1.1.0' to my xcode project with minimum deployment target 14.0 and expected to use it

Answer 1

Please try to install both compilers (5.6 and 5.7) on the build machine and then check.

Users with a similar issue were able to fix the issue by following the steps outlined in this SO thread . Quoting here for your convenience.

“You need to set the Build Settings > Build Options > Build Libraries for Distribution option to Yes in your framework's build settings, otherwise the swift compiler doesn't generate the necessary .swiftinterface files which are the key to future compilers being able to load your old library.

This ends up in your project.pbxproj file as: BUILD_LIBRARY_FOR_DISTRIBUTION = YES;

Please try the above steps and let us know how it goes.
