Building a native plugin for iOS with swift Library

Hi,

I’m having trouble building my iOS swift library since the update to 2019.3. With 2019.2 everything still works.
The problem seems to be that the properties that I set for the Xcode project like so do not get set properly in the Xcode project in 2019.3.

                var targetGuid = proj.TargetGuidByName(PBXProject.GetUnityTargetName());
                //// Configure build settings
                proj.SetBuildProperty(targetGuid, "ENABLE_BITCODE", "NO");
                proj.SetBuildProperty(targetGuid, "SWIFT_OBJC_BRIDGING_HEADER", "Libraries/UnitySwift/UnitySwift-Bridging-Header.h");
                proj.SetBuildProperty(targetGuid, "SWIFT_OBJC_INTERFACE_HEADER_NAME", "unityswift-Swift.h");
                proj.AddBuildProperty(targetGuid, "LD_RUNPATH_SEARCH_PATHS", "@executable_path/Frameworks");
                proj.SetBuildProperty(targetGuid, "SWIFT_VERSION", "5.0");

If I replace

var targetGuid = proj.TargetGuidByName(PBXProject.GetUnityTargetName());

with

var targetGuid = proj.GetUnityMainTargetGuid();

all properties in XCode get set as user defined variables in 2019.3 while in 2019.2 they get set properly as config for the swift compiler.
If I set it as

var targetGuid = proj.GetUnityMainTargetGuid();

the properties do get properly set for the swift compiler but I get an error saying “using bridging in headers with framework targets is unsupported”

Any suggestions how to fix that?

Thx in advance!

I’m struggling with the same issue, did you find a solution for this?
