    [BUILD TIME] Several errors similar to Bad receiver 'int *', Unkown type name 'InBrain'...

    First check that the framework target membership is correctly set. If the problem still occurs, and you are trying to create a release build with a simulator as target (and you are using XCode 12), please add arm64 in the Excluded Architecture of your project and 'inbrain-surveys' pods (see this post for detailed information)

    [BUILD TIME] 'InBrainSurveys_SDK_Legacy/InBrainSurveys_SDK_Legacy-Swift.h' file not found

    This problem usually happens if the framework is not set in the Embedded Binaries, or if the framework doesn't have the target set to inbrain-surveys See above for set up. Clean and build the project after changes.

    [RUNTIME] Library not loaded: @rpath/libswiftCore.dylib

    This problem can happen if your project doesn't have the Swift standard libraries included. Set the 'Always Embed Swift Standard Libraries' to yes in your target to fix it. Clean and build the project after changes. This problem also consistently appears when usinx XCode10

    [RUNTIME - Release scheme] dependent dylib '@rpath/InBrainSurveys_SDK_Swift.framework/InBrainSurveys_SDK_Swift' not found

    This problem happen with previous version of Cocoapods and XCode. Try updating to Cocoapods 1.10.x, and if it still doesn't work, also upgrade to XCode12

    [DEVELOPMENT] When running 'pod install' in APP: "Specs satisfying the inbrain-surveys (from ../node_modules/inbrain-surveys) dependency were found, but they required a higher minimum deployment target."

    => Modify the platform version in 'APP/ios/Podfile'

    [DEVELOPMENT] When building in XCode: No matching function for call to 'RCTBridgeModuleNameForClass'

    Update from RN0.62 to RN0.63

    [DEVELOPMENT] When building in XCode: problem with not finding switch libraries
