answer: nothing will happen automatically, you start the migration manually. do i have to implement all attribute mappings for all entity mappings? answer: no, i didn’t have to implement any of those. i use magicalrecord, how is it going to affect the process of implementing custom migration. answer: you don’t start using magicalrecord until after the migration is completed core data model versioning and data migration programming guide is talking about core data migrations in general. there is a section about customising the migration but it’s very short and leaves you with a lot of questions unanswered. i had to use information from several different sources on the internet to finally understand custom migrations. overall, the process of figuring out how to implement custom core data migration felt like collecting a jigsaw puzzle without knowing beforehand what the end picture would look like. so, what i intend to do with this post is to give you a bird’s eye view on the work that is needed to be done in order to implement custom core data migration. i’ll use my app as an example, but this post is not so much about the little details and code snippets as it is about the overall strategy of implementing custom migrations. you can find all the code snippets you need on stack overflow. and i don’t talk much about theory either. this is not an in-depth guide to core data migrations. hopefully, you’ve already read some theory, but maybe still need an example of how it’s done from start to finish. you will find such an example here. as for me personally, when i was learning all this stuff, what i found myself lacking, is an overview or some king of a big picture. i hope this post will give you this big picture. this post focuses only on custom core data migrations. so, before reading further, make sure you have general understanding of core data and lightweight migrations. the original project first let’s take a look at my app. we’ll see what its data structure was before and after the migration. the original app had a list of questions which you were supposed to answer on a daily basis. this is what a question list looked like and these are the entries in the diary i told you that i’d made some funny decisions about the data structure of the app. here’s what it looked like. for the list of questions i had a class called questions . there was only one object of that class. it had one attribute called questions of type binary data. an archived array of nsstrings was stored there. for daily records i had a class called records (for some reason the name of the class was plural). it had three attributes: date – i stored dates as strings that looked like this 2017-12-30 . the reason i didn’t use nsdates was that at the time i wasn’t comfortable with timezones. i needed dates to always be the same after the entry was created. what if i used nsdates and a user changed the timezone? some dates could change as a result. i figured it would be easier to store the date as a string and don’t have that problem. in the new version i fixed this, and you’ll see how later. questions – an archived array of strings with question names; answers – an archived array of strings with answers to the questions. i made sure in code that questions and answers arrays always had the same number of items. question of index i had a corresponding answer in answers array, also at index i. if there was a question which had no answer, i stored [nsnull null] in the questions array in place of an answer to that question. i know, very strange decisions, but that was my first experience in app development. data structure after the update the main reason for the update was to have multiple lists of questions. so, instead of one list of questions i now have several lists of question. each list has a name and a bunch of questions. and each day record in the diary can now contain multiple entries, like this: the lists of questions are now called templates. you can see them in a list on the templates screen. when you edit each template you can see that now there are 3 types of questions: text, number and yes/no. these are really the types of answers a question can have. to better understand all this, i suggest you download the app and explore “my diary” and “templates” sections in its menu. the new data model looks like this: there are templates now. each template has a name and a list of templatequestions. each dayrecord has a list of sectionrecords, and each sectionrecord has a list of questions. when to implement the migration in your development process now that you’ve seen ‘before’ and ‘after’ versions of the app let’s do the migration. but first let’s talk a bit about when to do the migration. at first i had this crazy idea of releasing the version of the app that would look and feel just like the old version but would have the new data model. i thought i’d do the migration, see that everything’s ok and then start developing the new ui in the next version of the app (the migration part was kind of mysterious for me at that time, and i just wanted to figure it out first and then continue with the rest of the development process). i started out with this approach but soon realised that it just wasn’t
