1）clang: error: linker command failed with exit code 1 (use -v to see invocation)
You need to right-click Reveal in Log to view the specific error reason
2） dyld: Library not loaded:
dyld[15027]: Library not loaded: @rpath/HappyDNS.framework/HappyDNSSolution: TARGETS > General > Frameworks, Libraries, and Embedded Content, select HappyDNS, and set Do not Embed on the right to Embed & Sign
3）unexpected duplicate task:
Solution: File > workspace settings > Legacy Build System
4）Building for iOS, but the linked and embedded framework 'HappyDNS.framework' was built for iOS + iOS Simulator.
Solution 1: Regenerate the framework that supports iOS + iOS Simulator (not provided by a third party)
Solution 2: File > workspace settings > Legacy Build System
5) The class declaration of OC in PCH must be placed in #ifdef __OBJC__ , otherwise it will be defaulted to the class declaration of C language and an error will be reported.
6）#import "<MKKit/MKKit.h>" file not found
Solution: Add the corresponding class library and check the search paths
Abnormality in uploading ipa
1）contains unsupported architectures [x86_64,i386]
Solution: TARGETS > Build Phases > Click '+' > New Run Script Phase > Then copy and paste the following code
APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
# This script loops through the frameworks embedded in the application and
# removes unused architectures.
