You didn't include the libz.tbd where those functions are. Select the project node, select your target, go to the Build Phases tab, expand "Link Binaries With Libraries", add libz.dylib, and try again.
您没有在这些函数所在的位置包含 libz.tbd。选择项目节点，选择您的目标，转到 Build Phases 选项卡，展开“Link Binaries With Libraries”，添加 libz.dylib，然后重试。

Add libz.dylib to your framework, it will work..
将 libz.dylib 添加到您的框架中，它将起作用。

I faced the same issue, and thanks to Jano, it was resolved after I added the Libz.dylib to the project.
我遇到了同样的问题，感谢 Jano，在我将 Libz.dylib 添加到项目后解决了这个问题。
