Tribute to Mantle

As Swift getting matured and Mantle will not be maintained for Swift, I put this presentation as a tribute for one library that I use quite often when producing MVP.

4. API CoreData Mantle
5. Mantle . . . MTLModelSubclass *transaction = [MTLJSONAdapter modelOfClass:[MTLModelSubclass class] fromJSONDictionary:response[@"data"] error:&error]; . . .
6. Mantle - Pros It simplify JSON parsing and mapping Fully support NSCoding & NSCopying Extensible Archivable (NSKeyedArchiever or NSManagedObject)
7. JSON MAPPING @interface GHIssue : MTLModel <MTLJSONSerializing> // your .m file . . . + (NSDictionary *)JSONKeyPathsByPropertyKey { return @{ @"propertyName": @"key_from_api" }; } . . .
8. JSON MAPPING - CUSTOM // your .m file . . . + (NSValueTransformer *)propertyNameJSONTransformer { return [NSValueTransformer valueTransformerForName:MTLURLValueTransformerName]; } . . .
9. EXTEND YOUR CLASS // your class which extend from class that implement MTLJSONSerializing // your .m file . . . + (NSDictionary *)JSONKeyPathsByPropertyKey { return [super.JSONKeyPathsByPropertyKey mtl_dictionaryByAddingEntriesFromDictionary: @{ @"propertyName": @“key_from_api" } ]; } . . .
10. ARCHIVE - NSManagedObject @interface GHIssue : MTLModel < MTLManagedObjectSerializing > // your .m file . . . + (NSString *)managedObjectEntityName { return @"YourEntityName"; } + (NSDictionary *)managedObjectKeysByPropertyKey { return @{ @"managedObjectProperty" : @"yourProperty" }; } . . .
11. ARCHIVE - NSManagedObject @interface GHIssue : MTLModel < MTLManagedObjectSerializing > // your .m file . . . + (NSSet *)propertyKeysForManagedObjectUniquing { return [NSSet setWithObject:@"uniqueProperty"]; } + (NSDictionary *)relationshipModelClassesByPropertyKey { return @{ @"propertyThatContainOtherObject": Song.class, }; } . . .
12. Mantle - Cons It fetch all - No partial fetch It use lot of memory (if you have large data set and fetch it all at once)
