   The crash seems to happen only if the framework is used via Carthage.
   With CocoaPods works fine

   It's different between 32CPU and 64CPU

   If your json is :

   {
   "a": "1",
   "b": "1"
   }

   but you model is:

   @property (nonatomic, assign) BOOL a;
   @property (nonatomic, assign) NSInteger b;

   Will be crash in 32CPU:

   -[__NSCFString charValue]: unrecognized selector sent to instance 0xxxxx
   -[__NSCFString longValue]: unrecognized selector sent to instance 0xxxxx
   

   How to fix:

   1. Change service json format to:

   {
   "a": 1,
   "b": 1
   }

   2. Add a category for NSString：

   @interface NSString (JSONModel)
   
   #if __LP64__ || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64
   #else
   @property (nonatomic, assign, readonly) NSInteger longValue;
   @property (nonatomic, assign, readonly) BOOL charValue;
   #endif
   
   @end

   @implementation NSString (JSONModel)
   
   #if __LP64__ || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64
   #else
   - (NSInteger)longValue {
       return [self integerValue];
   }
   
   - (BOOL)charValue {
       return [self boolValue];
   }
   #endif
