I'm trying to generate NSManagedModels from my datamodel. Generation works but after I got many errors :
error: filename "Station+CoreDataProperties.swift" used twice:
'/Users/Me/MyApp/Models/CoreData/Station+CoreDataProperties.swift' and
'/Users/Me/Library/Developer/Xcode/DerivedData/MyApp-gwacspwrsnabomertjnqfbuhjvwc/Build/Intermediates/MyApp.build/Debug-iphoneos/MyApp.build/DerivedSources/CoreDataGenerated/Model/Station+CoreDataProperties.swift'
:0: note: filenames are used to distinguish private
declarations with the same name
I try clean build folder and derivedData directory hard delete. I'm using Xcode 8 BETA maybe it's a bug ?
I get this in Xcode 8.1
For me following steps solved the issue. Please note that order matters.
1) Create entity in Core Data model.
2) Under class section, make settings as on following image.
Module: Current Product Name
Codegen: Manual/None
3) Generate your NSManagedObject subclass.
This post greatly helped me solve this problem myself. Personally I look at this as an Xcode bug. Bug or not this is a huge chicken and egg situation.
I ran into this by:
Created a new Project using Core Data
Generated my NSManagedObject subclass+extension (while codegen: ClassDefinition)
I accidentally saved the generated classes in the Wrong folder
I deleted the generated files
Re-generated in folder I wanted
đź’Ą- Xcode used twice errors
As others have posted I kept cleaning my build (and clean build folder) but that never fixed the build issue.
I finally figured out if you originally created your NSManagedObject generated classes with codegen: ClassDefinition, as I did without knowing then you are locked in for the chicken and egg issue.
I then deleted the auto generated classes thinking I had to re-generate, so I did. Once re-generated I would get the used twice build error again. I manually went into the ../DerivedSources/CoreDataGenerated/Model/.. and deleted the duplicates. Again, I re-generated thinking I'd only have 1 copy (in my project) but I was wrong. If codegen: ClassDefinition was originally set then Xcode will keep creating the auto-generated classes+extensions and put them in the buried folder ../DerivedSources/CoreDataGenerated/Model/... I repeated this chicken and egg a few times before catching on.
I later realized you do indeed need to mark codegen: Manual/None however to get things back in sync you need to delete the auto-generated files in ../DerivedSources/CoreDataGenerated/Model/.. and in your project if you have any there still.
Be careful setting codegen: Manual/None, for me it was bit tricky because codegen: Manual/None wouldn't stick. I had to click back and forth between entities multiple times to double/triple check each entity was set to codegen: Manual/None. Then auto generate the files. At this point your only copy of the auto generated files should be in your project and not in ../DerivedSources/CoreDataGenerated/Model/...
Last, I think this is a bug because if you specify codegen: Manual/None I don't expect Xcode to auto generate files at all, yet it does and puts them in your project. More confusing if your setting is codegen: ClassDefinition, who the heck knows Xcode will put the files in a buried directory yet it is available for use in your project. My beef with this is the auto generated files aren't source controlled and if I change computer I have to know to auto-generate them on the new station.
Hope this helps someone else!
Cheers!
This is indeed not a bug. As #Morrowless suggests both class definition and properties extension are created. If this is not wanted, select Manual/None under Codegen before generating the code. If the code is already generated, just delete them, and try Editor->Create NSManagedObject Subclass... again from the menu (after setting Manual/None).
Note, in the picture below, the Class Name 'Contact' is specific to my project. You will see your entity name instead.
If you generated CoreData subclasses with codegen: ClassDefinition your basically screwed. The only way to fix it is to:
Delete your CoreData subclasses.
Delete your derived data folder.
Clean your project (CMD+K).
Generate new CoreData subclasses, this time select Codegen: Manual/None and Module: Current Product Module
This is not a bug. Codegen generates these files in the DerivedData folder, so you don't need to create them again in your project, hence the compile error.
From Xcode 8.0 Release notes:
Xcode automatically generates classes or class extensions for the entities and properties in a Core Data data model. Automatic code generation is enabled and disabled on an entity by entity basis, and is enabled for all entities in new models that use the Xcode 8 file format. This feature is available for any data model that has been upgraded to the Xcode 8 format. You specify whether Xcode generates Swift or Objective-C code for a data model using the data model’s file inspector.
When automatic code generation is enabled for an entity, Xcode creates
either a class or class extension for the entity as specified in the
entity's inspector: the specified class name is used and the sources
are placed in the project’s Derived Data. For both Swift and
Objective-C, these classes are directly usable from the project’s
code. For Objective-C, an additional header file is created for all
generated entities in your model. The header file name conforms to the
naming convention “DataModelName+CoreDataModel.h”.
However, if you selected Category/Extension under the codegen pulldown menu in the data model inspector (because you want to add logic to your model): codegen will wrongly generate both the class definition and properties extension.
The solution is to simply delete the properties extension (ClassName+CoreDataProperties.swift). Your project should now compile.
After following the guidance from oyalhi and Vladimir Shutyuk, (deleting the NSManagedObject files, changing the entity codegen to Manual/None), I had to restart Xcode to allow it to index again before I could re-generate the NSManagedObject files and get a successful compile.
For the sake of completeness..:
I just ran into the same error, but none of the proposed solutions worked. What puzzled me was that even switching from automated code generation to manual for the one (as I thought) problematic entity didn't do anything.
Finally, I figured out that I had several entities with the same name, but they all shared the same classname. The reason for this was that I copy&pasted one entity several times to save me some work, because they also have a few attributes in common.
Turns out XCode renames the duplicates by adding 1, 2,... to the entity name, but leaves the class name as before. And since now entity name and class name are "unrelated", renaming the entity won't change the class name either.
Hope it helps someone - I have also filed a bug report for this.
To remove the stale object issue(ie..when we run the test script for multiple input,it fails for the second iteration as the object is not cleared at the end of each run)in my script, I have added always search configuration in the designer file. After this my script runs successfully on multiple inputs, but if there is a need to add some objects newly to the same designer file then my designer file will be regenerated and the Always search configuration changes will be lost.
Is there any way to retain the always search configuration remain in the designer file ever even when the designer file is regenerated?
When you generate a UI map there are actually two files that come with it. Firstly, as you've discovered, there's a generated file with all the ugly code that's generated by the coded UI test builder. Of course, making any changes to this outside of the code will regenerate the file. The second file is a partial class that accompanies the generated designer class. This file does NOT get regenerated but as a partial contains all the same object references and properties as the designer file (it just looks empty). You can reference the control you want to add this property to here and it will not be regenerated.
The other alternative to this, albeit probably not a good idea, is to put
Playback.PlaybackSettings.AlwaysSearchControls = true
inside of your test method/class initialize/test initialize. This will force the test(s) to always search for each and every control. As you might imagine, this can have a significant performance impact though when you're dealing with large UI maps or particularly long test methods.
You might also set the control object's search configuration to always search. Keep in mind that this will do searching for this control and all of it's children so I would not advise putting it on a parent with several children, such as the document.
aControl.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
I'm attempting to make a Resharper plugin to help do some specialized refactoring on a project I've got.
The gist of it is that I have a static function in a class and I want to create a new class and move the static function into it.
I thought it was going to be much more straightforward but I'm having difficulty finding examples or starting points in the SDK documentation.
Specifically, I can't figure out how to create a new file contains a new class. While I can't say for certain, I feel like I've run across a couple of examples of creating a new class (though I ignored them at the time because I was hung up on this new file thing).
Does anyone know the magic words to make the ReSharper SDK create this new file?
Creating a new file can be as simple as CSharpElementFactory.CreateFile but you might also want to consider using a refactoring instead. What you can do is create your new class, put the method in there, add it to the current file and then execute MoveIntoMatchingFilesRefactoring.
I need some information about Static Library creation, Actually i was created static library with .h(header files) files, But i want to hide some .h(header files) from my library which are not visible to others. Could u please provide any solution..
Yes, there is a possibility and I have done this very recently.
Please refer this website which shows how to expose the header files.
Note: You should not import your private headers in your public headers. You'll get some compilation errors while compiling the library in other projects.
Lets assume you have two headers,
XYZ.h (public)
XYZInternal.h (private)
You have to import XYZInternal.h in XYZ.m file to avoid the header not found error and of course to hide the existence of the private header/class.
I have a referenced assembly that has a (devart) Linq Datacontext in it. We use this same assembly in a bunch of other projects and I don't want to add the source code to my current solution.
How can I add some of the classes in it to a ClassDiagram in my current project?
EDIT in Response to Comments/Answers
I don't have access to the original source code of the external project.
What I mean't was when I said "I don't want to add the source code to my current solution." was I don't want to build up a bunch of partials in my current solution either.
Include a reference to the library in your project.
Go to the object browser (View->Object Browser) and search for your class.
Drag and drop it from the object browser onto the design surface.
I tried it with System.Random and it pulls all the properties and methods.
