1、clone the code
2、open with Xcode 12.2 then I got this error:

Hi peixuan197.

Try creating a file named Podfile in the root directory (the same folder containing GTXiLib.xcodeproj) with these contents:

target 'GTXiLib' do
  pod 'Protobuf-C++'
end

Then run pod install, and open GTXiLib.xcworkspace. Not GTXiLib.xcodeproj. You can install CocoaPods using gem or Homebrew.

GTXiLib now requires Protobuf support. By far the easiest way to support this is CocoaPods. You can build Protobuf from source, but it's much more complicated. You need to build the proto compiler for "cross compilation", because you're running the compiler on MacOS but generating output for iOS.

The newest version has fixed this issue. See below:

Your Podfile should look like

use_modular_headers!
target "NameOfYourProject" do
  pod "GTXiLib"
end

with an optional version specifier for "GTXiLib". Note the use_modular_headers! line and the lack of use_frameworks!. As of CocoaPods 1.5.0, use_frameworks! is no longer required for Swift projects. use_frameworks! makes Protobuf-C++, which is a dependency of GTXiLib, fail to import properly. Thus, you cannot use use_frameworks!, which means you must use use_modular_headers!. You may also specify :modular_headers => true on a per-pod basis. Then, add import GTXiLib to your Swift files, and you can use GTXiLib APIs.

I should note that I wasn't able to make this work using the per-pod basis installation (:modular_headers=>true)

An alternative approach is to use version 3.1.0 which doesn't use Protobuf.

CooperCorona's recommendation to use the 'Protobuf-C++' pod in conjunction with specifying use_modular_headers! as kkorouei suggested did the trick for me.
