Users of my application keep running into issues related to other applications declaring a different UTI for the same file extension as my application. I think I can best describe this with an example:
My application supports importing and exporting OPML files. For this to work I import the org.opm.opml UTI in my info.plist. This mostly works fine, but fails if an other application declares a different UTI for the opml file extension. For example com.redlex.opml or com.xwavesoft.cloudoutliner.opml.
Is there something I can do to work around this problem? Can I somehow tell launch services that my application accepts all files with an .opml extension?
I solved this issue with the following work around:
I removed the entire LSItemContentTypes entry from the list of CFBundleDocumentTypes
In my NSDocument subclass I use NSString's rangeOfString:: method to look for the #"opml" keyword in the typeName parameter.
This work around was confirmed by a user.
Cloud Outliner updated on the MAS today, and looking at the UTI for .opml files now, the com.xwavesoft.cloudoutliner.opml is now gone and com.redlex.opml is now in its place. Which would be uninteresting, except for the fact that OPML files now open in MindNode without a problem.
I can't find any release notes for Cloud Outliner other than "various fixes and improvements." but it would seem that something changed for the better. So: in my case - the simple answer was "update Cloud Outliner" but I'm not sure this solves the larger problem. I also have Mellel on my system (obviously, right?!) but this doesn't seem to be causing the same issue.
For those watching this thread - the issue presented as MindNode showing greyed-out icons for OPML files in its open dialog. Dragging OPML to the MindNode icon in the dock also produced no results.

iOS 10 / Xcode 8 GM build getting the below, never had it before on Xcode 7. Any ideas?
objc[25161]: Class PLBuildVersion is implemented in both
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices
(0x12049a910) and
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices
(0x1202c4210). One of the two will be used. Which one is undefined.
(NOTE: Only seems to happen in simulator, does not appear on real device).
Main Idea
Main idea is simple:
If your app (or dependencies, such as Pods) uses framework, that uses explicit (or implicit) PhotoLibraryServices.framework or AssetsLibraryServices.framework as dependency, Xcode warns you (even if you are using only one of them). It might be Photos/PhotosUI.framework or AssetsLibrary.framework, or another (I don't have full list of dependencies, but it is possible).
What is the problem?
Class with name PLBuildVersion is defined in both PhotoLibraryServices.framework and AssetsLibraryServices.framework. Class name is unique in Objective-C (you can't define 2 classes with same name), so it is undefined which one will be used in runtime.
However, I think that it will not be a problem, because both classes have same methods and fields (checked this with disassembler) and I guess that both were compiled from the same source.
Radar is already sent.
As per answer from Apple employee on Apple's Developer Forum:
You don't control either of the class sources listed, so there isn't anything you can or should do – aside from Reporting a Bug.
I was unable to find a way to get rid of the warning, but if you want to prevent the app from crashing, you need to provide a description for why you are accessing the camera, photo library, etc. This is new in iOS10.
Input the following into your Info.plist file.
Photo
Key: Privacy - Photo Library Usage Description
Value: $(PRODUCT_NAME) photo use
Camera
Key: Privacy - Camera Usage Description
Value: $(PRODUCT_NAME) camera use

I find you can get this error merely by using a UIWebView. My solution was to replace my use of UIWebView with WKWebView.
I had this after adding Answers on Fabric to my project.
Deleting derived data did the trick for me. (shift alt command k in XCode)
Edit a year later:
After deleting derived data, always exit XCode and start it again.
In unrelated cases I have the impression that deleting derived data does not clear XCode’s in memory caches of the derived data.
Resetting the iOS simulator fixed this for me. Simulator -> Reset Content And Settings.
In my case this warning started to appear after opening a second xcode project and running the second app on the simulator. After changing back to the first app, the warning started to appear. I just quit the Simulator and Xcode and reopened my project. The warning disappeared after that. If that doesn't solve it, proceed with the other answers. Xcode can be really picky sometimes.
I have created the document picker extension(Both File provide and document picker , with the default implementations) and when i try to open the extension using the DocumentPickerViewController, its immediately closing the DocumentPickerViewController by showing the below issue
plugin com.apple.UIKit.fileprovider.default invalidated.
I have setup the basic app groups and iCloud entitlement as well, Which are all fine. Even from the documentViewController the default iCloud is working perfectly fine.
Actually i am testing the extension using the same container application.
If somebody can provide some insight about this behavior, it would be a great help !!
Thanks,
Vishnu
I got the issue, actually the value of NSExtensionFileProviderDocumentGroup key was put incorrectly put on the info.plist of the file provider extension by XCode by the time of adding the App group.
Then I compared the files with the NBox sample from Apple and finally figured it out.
So sometimes beware of XCode automatic actions, make a cross check so to save to time.
I have been developing an OSX app with Delphi XE3 and running into various problems. The latest one is with the sanboxed version built for the Apple Appstore.
The user has to select an arbitrary folder and the app needs to get access to it. Since there is a problem with the OpenDialog, I had to turn to drag-drop functionality instead.
The user drags a folder to the app, the sandbox gives the app temporary access to it and all works properly.
To preserve the access to this folder when the app is restarted I have to use the so-called "security-scoped bookmarks"
I am having two issues with them:
1) How to add the "com.apple.security.files.bookmarks.app-scope" entitlement to an XE3 firemonkey app? It is not available in the Project Options->Entitlements. If I add it manually in the ".entitlements" file it gets overwritten when the app is built.
So is there a way to add a custom entitlement that is not in the list in the project options?
2) To create the bookmark I should use the NSURL.bookmarkDataWithOptions method. I think it should be used like this, but I am not sure of the exact syntax:
var
URL: NSURL;
Err: NSError;
Data: NSData;
...
URL := TNSURL.Create;
Data := URL.bookmarkDataWithOptions(NSURLBookmarkCreationWithSecurityScope, nil, #Err);
...
Maybe there should be a call to Wrap(...) instead of Create.
I have not yet experimented with it, because it is pointless without the answer to issue 1).
It seems no one has written anything about these problems for Delphi, but I hope someone here has experience with that.
Thanks in advance.
Edit:
For problem 1) I tried to add edit manually the ".entitlements" file in the OSX32 folder and set it to read-only to prevent it from being overwritten. It was too easy to be true of course, because the linker complained that the file can not be modified...
OK, I finally found the way to manually add entitlements that are not available in the Project Options > Entitlements.
Instead of selecting the "App Store" build in the Project Manager you have to select a Normal release build and deploy the application as usual.
The application gets deployed in the PAServer scratch-dir as APP package. Inside this package there is an "Entitlements.plist" file, which is in XML format and can be edited with a text editor. It is quite obvious how to add new entitlements once you open the file.
After it is edited, the app has to be code-signed manually and a package has to be prepared. It is slightly more complicated than using the Delphi IDE, but there are instructions about it on the Embarcadero and Apple websites and it actually went without problems.
Still haven't tried the bookmarkDataWithOptions functions.
An alternative could be to deactivate the checkbox for the entitlements-file in the deployment page.
But attention: Evry time you change between Build/Release or App Store/Normal, delphi activates the checkbox. That means you have to deactivate it again in the deplayment-page, to avoid the transfer of this file to the mac PC.
By the way: Do you have tryed meanwhile the StartAccessingSecurityScopedResource function?
In the MacApi.Foundation unit the function is not declared in the NSURL interface.
Do you have found a way to use this function?
I've read all the tickets about this issue, but I still don't get it right. I have a non-document OSX app (for OSX Lion and MountainLion). I want this app to export and import custom data, associated with a custom file extension ".iobs". Internally, these files are just data archived with [NSKeyedArchiver archivedDataWithRootObject:], and saved onto the disk with the "iobs" extension.
So, my check list is this:
1) Export mechanism: checked. My app create correctly .iobs files. If I run "file <filename.iobs>" in the Terminal, I get "iObserve_exportedItems.iobs: Apple binary property list"
2) Declaration of an exported UTI, checked. As shown in the image below. I did NOT declared a custom Document type, since it I never use NSDocument inside my app, and there is no point. Anyway, I already tried and failed. I've tried also different combinations of "Conforms To" entries, but with no success.
3) Is there any 3rd point??? Do I need to start my app once to let the system know? I just ran it in Debug from Xcode so far, and this has no effect. So I guess my Info.plist is wrong, but I filled it from within Xcode4 interface, so???
Thanks for any help, hint, question, suggestion.
Ok, so apparently, I do have to declare a document type even if I don't specify a document class. See the attached screenshot. Note that leaving only the Document UTI doesn't work. I do need the two (exported UTI and document type). Note also that if I say it conforms to com.apple.binary-property-list, I don't have the right icon.
And for those who wonder, there is nothing to do to "register" a type (and its subsequent changes) apart from launching the app once.
Dropbox has the option of adding a button to the Finder toolbar. It even appears in the 'Customize Toolbar...' window.
I can't find any documentation on how this sort of thing is done.... Does anyone know how to do this, or can anyone point me towards some documentation or sample code?
EDIT ONE:
I guess a start would be finding the location of the existing icons, and any related code.
I noticed that Dropbox has files in Library/DropboxHelperTools/Dropbox_u501 called mach_inject_bundle_stub.bundle and FinderLoadBundle which might be doing the magic. Dropbox is also putting the 'tick' badge on Finder icons. This code might be involved: github.com/rentzsch/mach_star
EDIT TWO:
A Dropbox talk by Rian Hunter about the process is here, at around 15:30
http://blip.tv/pycon-us-videos-2009-2010-2011/pycon-2011-how-dropbox-did-it-and-how-python-helped-4896698
Looking in the DropboxBundle file in the Dropbox_u501 shows the icons and some compiled code. The code suggests that Rian Hunter is the author: http://twitter.com/timeserena
Rian has his own version of the Mach Star code on his github - https://github.com/rianhunter/mach_star - tho it seems much older
EDIT THREE
There was a 'Code Injection Workshop' at Stanford a few weeks ago - http://stanfordacm.com/past/ - hosted by Rian. If anyone has notes from this please let me know!
You can use Finder Sync app extension(Starting in OS X v10.10).
A Finder Sync extension can:
Add, remove, and update badges and labels on items in a monitored folder.
Display a contextual menu when the user Control-clicks an item inside a monitored folder.
Add a custom button to the Finder’s toolbar.
Dropbox was using undocumented magic. There's no officially supported way to do this; the closest you can get without reverse engineering is Services.
(Update: As of macOS 10.11, what Dropbox was doing is no longer possible at all. System Integrity Protection now prevents code from being injected into system processes, such as the Finder.)
Rian's talk at PyCon 2011 (on blip.tv) does not explain anything more than "We reverse-engineered Finder." Although the mach_star stuff is valuable, it still doesn't explain how to get a sidebar icon working. And the Stanford 'Code Injection Workshop' has not posted any content about this method.
I've nm'd and class-dump'd both bundles that Dropbox installs for each user under /Library/DropboxHelperTools, and the output provides good insight. If I get back to it, I'll finish my research and post it. Odds are, it won't be for some time, so here's hoping this nudge helps someone else.
An easy intermediate answer that may be adequate for some people is to simply create icons that look like buttons.
e.g. I created 'new text file here' and 'new terminal here icons' for my Finder:
The method can be found here.
The disadvantage is that they must be square and do not have animations/menus or show up in 'customize toolbar' etc.
