I created my own iOS library with core data inside,
as suggested here.
I added library to my project and build is success, but when I am trying to load the database:
bundleWithIdentifier method for my bundle returns nil.
NSBundle * testBundle = [NSBundle bundleWithIdentifier:#"result.BIModel"];
// testBundle = nil;
My library's bundle identifier is set(see image below), I added the framework to "Link Binary With Libraries" and "Embed Frameworks".
What am I missing ?
EDIT :
I notice that when framework is created one file is missing.
I build test framework (that works and bundleWithIdentifier return bundle) and get (see last file),
but when I build my framework i get
. See that last file is missing.

basically I have some Objective-c class already existing and I want to use them in my NativeScript projet. Currently I have added those files to the Xcode project target and I want to be able to call my objective-c code from nativeScript js. I've read the doc but I don't understand it. It seems so complicated. basically currently all I want to do is be able to present my custom view controller by calling probably something along
const vc = MyCustomViewController.alloc.initWithNibName("xib file")
page.frame.ios.controller.present(vc,true, nil)
Am I obligated to create a plugin for that? Am I obligated to use my objective-c class to build a framework in Xcode and then import the framework?
So I found out.
Actually what you need to do is first to compile your native iOS code into a framework. As per the documentation all your classes must inherit NSObject and all your function must be marked with #objc to be exposed to the objective-c Nativescript side if you write in swift. You will notice as well that in a framework your bundle is not the main bundle. In this example you can see how you can retrieve the bundle from the framework and load a xib from it.
Then you need to add your framework file to a Nativescript plugin. For that, you want to add the framework to the plugin's iOS folder yourPlugin/platform/iOS/yourFramework.framework.
then, you need to add your plugin to your app. You can add your local plugin by using the next command line. Notice the path end with the /src folder.
tns plugin add /path/to/yourplugin/src
Now, you can then call your native functions and classes without even importing them. Of course this works only on iOS. If you run your app on android, calling those methods will crash.
To show this viewController on your Nativescript side you will need to call the following code. By the way You can find documentation elsewhere to get a reference to the current page or frame object.
const controller = page.frame.ios.controller
const vc = IOMediaViewController.create()
vc.modalPresentationStyle = UIModalPresentationFullScreen
controller.presentViewControllerAnimatedCompletion(vc,true,null)
I am trying to understand the best ways in which to bring native library code into a NativeScript plugin for iOS. I've had success in past bringing in a CocoaPod and accessing the symbols from that. So I want to create my own.
I follow the process for pod lib create TestPod to generate my library project. (https://guides.cocoapods.org/making/using-pod-lib-create.html)
The 'library' is a trivial test: it simply creates a class with a function that returns
a recognizable greeting string.
The associated "Example app" demo produces a text label that displays this string.
This all works as expected, all running in pure iOS world (written in Swift).
At the Nativescript side, I'm using the Nativescript Plugin Seed and I'm declaring my Podfile in the src/platforms/iOS folder as directed. My "plugin" (trivial as it is as a test), has the iOS-specific parts in the pluginName.ios.js file. I have a separate test method in here that verifies I can reach and use native iOS platform symbols (e.g. NSMutableString) and that works as expected. I want to do the same thing with native code imported from my library.
But when I bring the Podfile into Nativescript, it builds okay, but I'm not able to see any of the symbols as I would expect to see.
I generate typings and I don't find them either, but I do find a "TestPod.d.ts" typings file that declares some version info and a mysterious class named "UITest" that I did not define and bears no resemblance to my "SimpleTest" class, which I can't find anywhere.
I'm sure I'm missing something here that is probably obvious to the knowledgeable. But I'm unable to guess what it is. Any ideas?
import Foundation
#objc public class SimpleTest : NSObject {
public func announce() -> String {
return "Greetings from Swift code in a library"
}
}
I'm calling it in the plugin using the following:
public testNativeLib() : string {
let str:string;
try {
const testClass = new SimpleTest()
str = testClass.announce()
} catch(e) {
str = e.message;
}
return str;
}
and what I get returned for str is the catch case error message: "Can't find variable: SimpleTest"
Without seeing the source to the pod file; the only guess would be that you didn't use the #objc on anything that you wanted exposed. Without you exposing anything with #objc (or descending from a native objc class, so it is tagged by swift automagically) NativeScript cannot see it.
Please note their are some types in Swift that currently cannot be consumed by NativeScript (Or ObjC) and you have to write some wrapper code in swift around it using types that are compatible with ObjC so that NativeScript can use it.
Please see: https://docs.nativescript.org/guides/ios-source-code for more info on requirements...
The code needs to be:
import Foundation
public class SimpleTest : NSObject {
#objc public func announce() -> String {
return "Greetings from Swift code in a library"
}
}
Move the #objc to the actual property/function you want exposed. The NSObject will already cause the class to be exposed if it has exposed members.
The metadata generated:
A complete demo using a swift source file in a plugin is now located at
https://github.com/NathanaelA/demo-swift-plugin
If I have full control over the source, then I won't normally add another moving piece (i.e. cocoapod) to the mix; just let xcode compile the swift code and expose it, no need to add any additional places something can break.
However, if you want to see how to do an actual swift CocoaPod plugin; checkout any of these plugin repos that use swift code and cocoapod:
https://github.com/tomvardasca/nativescript-crypto
https://github.com/arpit2438735/nativescript-tglib
https://github.com/Daltron/NotificationBanner
In the case of an actual cocoapod; you need to have a valid Podfile, and a valid podspec file! Once you have those; when you build the application, you can open up xcode and verify that the cocoapod is linked in. If it isn't linked in then your podfile/podspec is messed up and has to do with a issue with Cocoapod and it is not a NativeScript issue. So in that case; you need to follow some Cocoapod tutorials to get it to work.
Please note; nuking your platform folder frequently while you are testing with cocoapods is highly recommended. Occasionally Nativescript does not detect the changes to Native code properly and so it then doesn't rebuild the xcode project/workspace files. So nuking your platforms folder will of course force it to rebuild them. If you don't you WILL waste a lot of time while messing around with cocoapods.
When running the sample project you will see this:
In addition, in the demo, the metadata generated from the code I saved in the demo/metadata folder so you can look at it.
I'm trying to use Hyperloop in order to use a third-party open source library. The library I want to use is Sweet Alert iOS.
The library has a swift file. I have put this file inside an src directory inside my project's main folder (does it have to be inside src folder? can I use other folder in my project? what about sub-directories?).
According to the Titanium documentation:
Any *.swift files found in your src directories will automatically be compiled
In my app when I do something like this:
var UIView = require('UIKit/UIView');
Ti.API.info('UIView => ' + UIView);
It works. But if I try to require any of the classes in the swift file I get an error that it can't find architecture x86_64 module.
var sweetAlert = require('SweetAlert');
var cancelAnimatedView = require('CancelAnimatedView');
When looking at the SweetAlert source code, I also notice that SweetAlert class is open while other classes are just regular classes:
open class SweetAlert
I'm not a swift developer so I don't really know what it means.
What am I missing here?
EDIT
Some progress... So I found that I need to have an appc.js file that's defining the src frame work and a name for MyFramework. And that the require I do should match the filename of the swift file. Now when I compile I see some more interesting output about the swift compilation, but getting an error:
[INFO] Generating metabase for swift MyFramework /Users/ophir/Documents/Appcelerator_Studio_Workspace/HyperloopTest1/src/SweetAlert.swift
2017-06-29T14:43:44.061Z | ERROR | An uncaught exception was thrown!
Cannot read property '1' of null
2017-06-29T14:43:44.064Z | ERROR | Cannot read property '1' of null
EDIT 2
I've cleared all the script in the swift file, and narrowed it down to the following failing script:
import Foundation
import UIKit
import QuartzCore
public enum AlertStyle {
case success,error,warning,none
case customImag(imageFile:String)
}
class SweetAlert: UIViewController {
}
class AnimatableView: UIView {
func animate(){
}
}
If I remove the func animate() { } it will not fail. Even if this function is inside that one SweetAlert class then it will fail. And from what I've read this is a pretty standard swift code.
So this makes me wonder - is Hyperloop 2.0.0(!) ready for production apps?
I receive a similar error when creating a simple Swift class and including it in a Titanium/Appcelerator project with the appc.js file set up just how they show in the sparse documentation. The project will compile with no issues and run in the Xcode Simulator, as long as I don't reference the class from the Swift file. If I reference that class in the project, the error arises. Based on the compile log, Swift files do compile into the project, but the classes don't seem to properly link in the end for "require"-ing into the JavaScript code.
When I search online for solutions, this same issue shows up all over, and the Titanium/Appcelerator team never presents a solution. I've tried Titanium SDK 6.0.1, 6.1.2, and 6.2.0, with all the same results; I've tried adding Swift code to existing projects and to new ones; I've also uninstalled and reinstalled Titanium/Appcelerator. (I've even tried running their sample app with no luck!)
Hyperloop does work when I use native frameworks, like UIKit, but it doesn't seem ready for production apps for 3rd party frameworks and classes.
I hope my discoveries help you and others to debug projects, but, unfortunately, I don't think I will be able to offer much help outside that.
I've been following this tutorial. This line of code returns nil...
let url = NSBundle.mainBundle().URLForResource(filename as String, withExtension: "caf")
Here's my resources...
Here's my build phase...
NSBundle(forClass: self.dynamicType) doesn't improve the situation.
The code worked when I dragged the sound file into the project instead of into the project's asset catalogue. I'm guessing that the latter's items are referenced by id instead of file name and type.
I also needed to add the sound file to the "Copy Bundle Resources" section in "Build Phases".
I have a need to create a packaging of UI classes that can be included in an XCode4 integration project by a developer and then get instantiated through the use of a config file in conjunction with NSClassFromString - a static plugin. I have had success with creating libraries that contain UIViews that layout based on code. Now I am trying to allow the developer to create UIs based on xib files and other resources. I am implementing the most basic version of this...a UIViewController loading a xib file created directly through the "new file" wizard in XCode4. The only modification I am making is adding a label to the UI in the xib.
I am having problems getting the xib loaded. If I include the xib in the integration project all is well. When I create the UIViewController from the library it finds the xib in the root of the app bundle and loads it. However, this is very cumbersome during the build of the integration project, I would like to be able to just link to the library and not have to add each xib to the integration project individually. Additionally the use of the root of the application bundle is bad because there is no directory structure that could facilitate multiple static plugins. I have tried creating a folder that the integration project can include during its build and the xibs for the static plugin can just be dumped into folder prior to build. If I do this the xib gets into the app bundle but when the UIViewController class loads up it cannot find the xibs. I have been unable to code a solution to get the UIViewController to initWithNibName:bundle: properly when the xibs are in the sub-folder.
My last attempt has been to create a static framework using this article: http://simplyitinc.blogspot.com/2011/04/creating-static-framework-in-xcode-4.html . That seems to get me a framework I can link against and the xib is in that framework directory but ... the xib does not get placed into the app bundle when I link against the framework. My classes are available but fail to load the xib, obviously because it is not in the app bundle.
Any suggestion on how this requirement might be accomplished?
