核心数据映射模型版本哈希值不匹配源模型版本哈希值

在启用Core Data Migration Debug的情况下，执行迁移时，会看到具有已更改哈希值的三个实体（2，3，4）。

With Core Data Migration Debug enabled, when performing a migration I see three entities (2, 3, 4) with changed hashes, as expected. Entity 1 doesn't change and is for illustration.

存储元数据（源模型）：

Store metadata (source model):

Entity1 = <67852e01 ...>; 
Entity2 = <2b68bba5 ...>; 
Entity3 = <58babd8d ...>; 
Entity4 = <1c694c80 ...>;

当前模型（目标模型）：

Current model (destination model):

Entity1 = <67852e01 ...>; 
Entity2 = <260e4d68 ...>;
Entity3 = <13360b6f ...>; 
Entity4 = <16513e1b ...>;

接下来，我创建映射模型，但映射模型中的散列与实际模型：

Next, I create the mapping model, but the hashes in the mapping model are different than those in the actual models:

映射模型源Hashes：

Mapping Model Source Hashes:

Entity1 = <67852e01 ...>; 
Entity2 = <2b68bba5 ...>; 
Entity3 = <d66bed18 ...>; // !!!
Entity4 = <2c56997a ...>; // !!!

映射模型目标散列：

Entity1 = <67852e01 ...>; 
Entity2 = <260e4d68 ...>; 
Entity3 = <cb08343c ...>; // !!!
Entity4 = <1bc2cf8c ...>; // !!!

使用不同哈希值创建映射模型的原因是什么？我查看了此问题，并尝试更新

What are the reasons the mapping model could be created with different hashes than the actual store's hashes? I looked at this question and tried updating the Mapping Model's models, but it didn't work.
