Solved - Fixing Dynamic linker error, dyld: Library not loaded issue in Xcode
If you get the below error while building in Xcode
dyld[596]: Library not loaded: @rpath/SomeFramework.framework/Core

Its generally a Xcode linking time error. Sometimes it may work fine in simulator but may fail in device. In all those cases, try debugging each step at once, and see if it resolves
1. "Build Settings" > "Build Options" > "Always Embed Swift Standard Libraries" to "YES".
2. "Build Settings" > "Swift Compiler - Search Path" > "Import Paths" to $(PROJECT_DIR) (recursive)
3. "Build Settings" > "Linking" > "Runpath Search Paths" to @rpath or @executable_path/Frameworks
4. "Settings" > "General" > "Frameworks, Libraries, and Embedded Content" and add the framework
5. "Settings" > "Build Phases" > "Embed Frameworks" and add the framework (both Embed with/without signing)
6. "Settings" > "Build Phases" > "Link Binary With Libraries" and add the framework.
7. "Settings" > "Build Settings" > "Dynamic Library Install Name Base" to "@rpath"
For every step you should do 1. Product -> Clean Build Folder. 2. Deleting DerivedData.
If above still doesn’t work , you could be facing file referencing issue. In such cases
You could do Xcode -> Product -> Build For Running and then go to your app’s derived data folder -> Build -> Products -> Debug-iPhone OS -> Look if your framework and its dsym file are there.
You could also build an ipa -> show package contents -> frameworks -> Look if your framework and its dsym file are there.
If its missing then you can look into properly adding it to your workspace, preferrably select copy files while adding your framework.
