I'm looking to give SearchKit a try for a little side project, but I'm having trouble finding out how exactly to import it. I've been hunting around online all day, and haven't found a solid example of anyone incorporating it into a project, let alone specifics of importing it.
I know that it is part of CoreServices, but simply importing that doesn't seem to give me access to SearchKit APIs. I was able to find a SearchKit.framework, but it's a MacOSX framework, not an iOS framework.
I feel like I'm missing something silly.. anyone have any ideas?
While SearchKit is used to provide the Spotlight search service, it is only directly accessible on macOS.
Core Spotlight is available on macOS and iOS.

I am trying to use the finder comment field of a file stored in the folder of my iOS application (I'm talking about local storage, not in the cloud). The function MDItemCreate that would enable me to do so easily is not available in iOS applications apparently, which must be why the build currently fails with the error warning : "Cannot find 'MDItemCreate' in scope". Apple documentation in fact states that this method is only available on MacOS.
I have tinkered with FileManager but it doesn't grant access to comments.
This topic seems related but the solution is quite opaque to me.
My understanding of Swift is rather limited, if you would be so kind as to provide a simple and detailed answer I'd be much grateful.
With thanks,
Julien
I'm not completely certain, but messages like "Cannot find 'X' in scope" are often due to a forgotten import statement. MDItemCreate(_:_:) (docs) seems to be part of the Core Services framework, which has been part of iOS since iOS 12. Have you imported the framework?
You can do this (at the top of your .swift file) as follows:
import CoreServices
I think I just must be stupid.
I'm having a lot trouble understanding very basic things concerning frameworks in Xcode/iOs/Swift. While I've certainly gotten some things to work, I've gotten more and more confused about what I'm actually doing. And the documentation on the web just confuses me more.
When I see discussions about how to import particular frameworks (e.g. https://github.com/danielgindi/Charts is the library I'm playing with, but I've seen this pattern repeated in other libraries) they seem to always tell me include the Xcode project file as a child project of my project, in addition to linking things as an embedded binary. This confuses me. Is it not possible to link an already compiled framework to my project without including all the source code of the project?
That is, can't I just take a library.framework file, and add it to my embedded libraries list and be done with it?
In the frameworks I've played with (again https://github.com/danielgindi/Charts is my primary example, but this is true in many others I've played with) I can't seem to use the framework without Carthage or CocoaPods. For me at this stage, that is just confusing... I accept that they are useful tools to automate a difficult process, but I'd really like to understand what that process actually is before I let a tool automate it for me. As I search the web I just seem to always be led back to these tools as being the correct way to do things.
So here are my questions.
If I find a framework library on the web... do I need its source code or can I somehow just link to a compiled version of the framework?
In my reading, it seems that libraries made with Swift are somehow second-class citizens because Swift is a newer thing. Is that still the case? (The articles I read about this seems to date from 2014-2015).
Is there are good place to understand how Apple expects me to add a framework to a project, without using CocoaPods or Carthage?
No need to add source code. Just add the framework to Target ->
General -> Linked Framework and Libraries -> Tap on + and select
your framework.
In my opinion, many new libraries are being written is Swift. So you won't be left behind for using swift.
Apple has documentation about adding frameworks to XCode. But I would suggest to use Cocoapods , as its easy to manage libraries.
Cheers :)
I'm looking for a library similar to https://github.com/amlcurran/ShowcaseView
I want to be able to implement forced tutorials on new users who open my application for the first time. Does anyone know where I can find a library that helps make this easy?
You ca try https://github.com/rahuliyer95/iShowcase
This is a quite similar iOS implementation of the ShowcaseView for Android (https://github.com/amlcurran/ShowcaseView).
This is an example of something that I have experienced a couple of times when working with MonoTouch:
I find a code example on the internet giving an example on how to use the NSUrl class. I try to add it to my code in Xamarin Studio. It is simple, except I can't find which using statement to use. I try to google, but no examples I find include the elusive using statement I am looking for. I find the the official Mac Developer Library NSUrl description, but it does not tell me much (or perhaps it tells me too much).
In general, how do you go about finding which using statement to use in a case like this? Is there a Xamarin documentation of this somewhere that I just can't find? I'm not looking for the specific namespace from the example, but how to go about finding it myself.
If it's an iOS API, it will always be
MonoTouch.<iOS Framework Name>
So if you found NSUrl, you should also be able to see that it is part of Apple's "Foundation" framework.
MonoTouch.Foundation
Of course, I would just recommend just letting the IDE figure it out for you.
Right-click (on NSUrl) -> Resolve -> "using MonoTouch.Foundation"
Is there any centralized repository of useful Objective-C / Cocoa libraries as there is for Perl, Ruby, Python, etc.?
In building my first iPhone app, I'm finding myself implementing some very basic functions that would be just a quick "gem install" away in Ruby.
There's a project for that! It's called CocoaPods!
Homepage: http://cocoapods.org/
Source: https://github.com/CocoaPods/CocoaPods
Unfortunately not :(
There are some very useful sites however. I find one of the best is cocoadev.com as it contains lots of useful information about many of the more obscure classes usually including snippets of code to do some really cool things :)
Maybe we (the cocoa community) should look into building something like this!
Oh and I just remembered this site cocoadevcentral.com which is also very good for starting out with cocoa.
Daniel mentioned http://cocoadev.com.
More specifically, check out http://www.cocoadev.com/index.pl?ObjectLibrary.
"This page is for tracking re-usable Cocoa classes that can be mixed, matched, and dropped fairly easily into existing Cocoa projects to add useful functionality."
I'd be interested in what kind of "basic functions" you're having to implement. There's actually quite a lot already there in the provided libraries, and I wonder if you're just not finding functionality that's already there...
There's a new index of reusable code for Mac OS and iOS: Cocoa Objects
I might be confused or missing something here... But doesn't apple provide all the Foundation / Cocoa / AppKit / CoreAudio / Qtkit / etc libraries that should provide all of the very basic functions you are looking for?
Other than what xcode comes with or is on the apple dev site, there are no centralized repo's for Cocoa.
Google Code also has some objective C things up. It depends on what you are looking for...
Also see GitHub, many useful Objective-C projects, especially re iPhone. See activerecord & cocoaoniguruma, for instance.

Google has Google toolbox for mac which got me started unit testing my iPhone application which was the main thing I found missing.
