1. Set the Release mode
1. First of all, choose here
2. Choose Run-> to change Debug to Release, select Close, and close
2. Run the project
1. In the real machine environment, compile the project
2. Compile the project in the simulator environment
3、选framework，Show in Finder
4. Find, the framework generated by the real machine and the simulator
3. Synthesis
1, lipo -info command, can detect the framework
lmydeMacBook-Pro:~ lmy$ lipo -info /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF
Architectures in the fat file: /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF are: armv7 arm64
lmydeMacBook-Pro:~ lmy$
Description: Armv7 arm64 is included in the True Set framework
lmydeMacBook-Pro:~ lmy$ lipo -info /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF
Architectures in the fat file: /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF are: i386 x86_64
lmydeMacBook-Pro:~ lmy$
Description: i386 x86_64 included in the True Set framework
2. Synthesis
lipo -create "/Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF" "/Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF" -output "/Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/OPDiscoveryDF"
The above command is too long, you can cd directly into the Products directory and execute the following short command:
lipo -create "Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF" "Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF" -output "OPDiscoveryDF"
Finally, under the Products/ directory, a full library containing armv7 arm64, i386 x86_64 was generated.
3. Replace, use
Replace the generated OPDiscoveryDF file with any OPDiscoveryDF.framework, and this OPDiscoveryDF.framework can be synthesized and used, supporting real machines and simulators.
