ios - 无法从 Cocoapods 渲染 SwiftUI 预览

Question

我有一个 SwiftUI struct 在我发给自己的公共(public)库中。

public struct NTextField: View {
    public var body: some View {
        Text("Hello, World!")
    }

    public init() {

    }
}

struct NTextField_Previews: PreviewProvider {
    static var previews: some View {
        NTextField()
    }
}

我点击文件，WYSIWYG 预览无法加载



单击“诊断”时，我看到如下内容:

Error Domain=com.apple.dt.UITestingAgent Code=-1 "failed to load library at path "/Users/<my_app_name>/Library/Developer/Xcode/DerivedData/<my_app_name>/Build/Intermediates.noindex/Previews/<my_app_name>/Products/Debug-iphonesimulator/<my_custom_pod>/<my_custom_pod>.framework/<my_custom_pod>": Library not loaded: 

有任何想法吗？我删除了派生数据，清理并构建。

还发现 this on the cocoapods git hub issue tracker .

您可以尝试在您的 Podfile 中添加它(如 JamesHurst 、 cltnschlosser 和 andersio 所建议的)

class Pod::Target::BuildSettings::AggregateTargetSettings
    alias_method :ld_runpath_search_paths_original, :ld_runpath_search_paths

    def ld_runpath_search_paths
        return ld_runpath_search_paths_original unless configuration_name == "Debug"
        return ld_runpath_search_paths_original + framework_search_paths
    end
end

class Pod::Target::BuildSettings::PodTargetSettings
    alias_method :ld_runpath_search_paths_original, :ld_runpath_search_paths

    def ld_runpath_search_paths
        return (ld_runpath_search_paths_original || []) + framework_search_paths
    end
end
