The static library and framework should be inside MinSizeRel/MinSizeRel-iphoneos/static_framework/.

build_ios/MinSizeRel/MinSizeRel-iphoneos/static_framework/onnxruntime.framework/onnxruntime

Note: The onnxruntime static binary does not have .a extension in this case

yes, i have got build_ios/MinSizeRel/MinSizeRel-iphoneos/static_framework/onnxruntime.framework/onnxruntime,but when i link this library in other project,it occurs errors。such as

ld64.lld: error: undefined symbol: std::__1::basic_streambuf<char, std::__1::char_traits>::~basic_streambuf()

can u tell me how to solve this problem?forward ur replay

You need to link the C++ standard library if it's missing std::basic_streambuf. Do your linker flags have -lc++ after the ORT library?
