Is it possible to generate JSON file from xcdatamodel?
Here's how I imagine it would work: Given a xcdatamodel file, going through some program with some custom logic (will probably be written by me), will generate JSON file for me to use in third-party library. My question: Is this possible? Has anyone ever done it?
The content of xcdatamodel is a content file with xml data and as bin file (no extension) so now it is easy to parse xml to json.

The help for swashbuckle mentions that the ui for Swagger is driven by the generated json schema.
Where is this json file located?
I cannot find it in the folder for my asp.net project
When I actually run the application and navigate to http://localhost:51659/swagger/v1/swagger.json
then I see the json
Where is it on disk? Or is it only in memory?
There is no file generated, it is only on memory.
You might want to read a bit the code:

If you need a file you could create an IDocumentFilter to generate one. I have an example here generating a Yaml file:

I searched the web for this one and mostly found Obj-C answers or outdated answers so ill simply post the question and hope for the best :)
Im working with a team of Android Developers while im working on IOS. they use XML files for a lot of data. since we want the data between us to stay consistent - we want to be able to have shared XML files to use in our projects.
I know .plist is basically a type of XML, but i want to be able to get the regular shared XML file and turn it into a .plist and then use it in my IOS project.
any known method of doing it at all? if so, is it possible to do it automatically somehow? (script or something of that sort. maybe even do it locally inside the application)
Thanks for the help
A .plist file is a very specific XML file with only a small set of keys allowed. A random XML file will not be convertible to a .plist file.
Try converting your file to JSON first. If you can convert it to JSON you will be able to automatically convert it to a .plist after that using the plutil command with the xml1 or binary1 format.
plutil -convert xml1 -o output.plist input.json
If you can't convert it to JSON, you can keep your XML file as is and parse it in your app using NSXMLParser. XML is harder to parse than .plist or JSON files, but aside from that the difference should be minimal.
I need to read xls files in my IOS app. First of all, I want to convert xls files to csv format files, then my app parse csv files, but I can't find any ios library to convert xls to csv, please help me
If you have a .xls file, you can use the open source DHlibxls library to read the file into your app. This is an ObjectiveC framework that wraps a C-based library. The library is quite mature.
ios or any objecive-framework doesn't provide any thing for accesseing Microsoft's xls :(
To convert-xls to/fro csv is itself a project in it!!!
On top of this, there are different format of xls, now xlsx files. And writing a xls and reading it back in proper way is tooooo-cumbursome task to accomplish. However we have managed to read it but it is not 100% efficient :(
I guess in near future you may want to move to xlsx file then your task will be a lot more difficult. You can check yourself, change the file name extension to .zip and unzip you will see many files, one having row numbers, another columns, third with links, fourth with contents and so on. Mapping and getting in correct form in not impossible but needs a lot of work.
There can be many other ways to do, I can suggest to use java api to do, or even save you xls to csv directory from excel, then your work will be easy.
I am new to IOS programming. I want to write a C style structure into file and retrieve back.
I am able to write string into file after getting Document directory path. But how to write a structure in that file. Can anyone help?
You'd likely be most interested in the NSCoding protocol, as well as the Creating and Extracting Archives and Encoding and Decoding Objects in the Archives and Serialization guide.
Normal C way of I\O operation worked well, however the to write file in particular location we need permission.
I have a upload text file field, and with it I plan to save the file somewhere and then store the location of the file in a database. However, I want to make sure the file they uploaded is a .txt file, and not, say, an image file. I imagine this happens in the validation step. How does one validate such a thing? Also, how do you get the filename of the uploaded file? I could always just check if it said '.txt' but for future reference knowing how to validate without just the filename would be helpful.
Trying to validate the contents of a file based on the filename extension is opening the door for major hackerdom. It's trivial to change the extension and upload the file.
If you are on a Mac/Linux/Unix-based system the OS "file" command is the standard because it looks inside the file for key bytes that flag file types. http://en.wikipedia.org/wiki/File_(Unix) I'm not sure what's available for Windows, but this might help: Determine file type in Ruby
One way of doing it, the simple way really, would be to pass the file through an image loader, preferably one that handles multiple common formats, and see if it throws an error.
The other way is to manually check the file header for common image format headers. For example, .bmp files start with BM. Other formats have their own specific markings you can use.
