I want to create iOS app which helps me to clean photo library.
Idea is simple - show all photos and videos from my iOS photo library with its sizes (regardless of where is media located - in iCloud or locally) with ability to preview them and to make selection for next deletion.
I have started to configure environment and figure out how to write apps with nativescript and can't google even how to get full list of photos/videos from iOS native Photos app.
Are there any limitations which will not let me to create an app described above in nativescript? Maybe it is not even possible to create in Xcode?
Is it possible to do in NativeScript? Yes.
It's very much possible. But you may not get the code you could just copy paste, you will have to understand the way plugins work & code marshalling (Objective C to JS).
The advantage of using {N} here would be cross platform UI, JavaScript as programming language for both iOS and Android, but you will have to use the native APIs to do the job.

I am beginner to building Apps with React Native + Redux.
I am trying to create an App family budget. It's almost done.
BUT I have two questions for them who already created these kind of apps.
What is the best way to save data? I want to save it (data: expenses/dates/category etc) on devices iOS (not database) if it's possible. I think it does not take a lot of memory. I've read about AsyncStorage, but not sure about it. Is it still present after reloading App/Phone?
How to share data between two users? I want to make a function, like sharing the budget between family members.
I will be very grateful for the recommendations and suggestions, maybe even for some good articles with explanation.
Thanks!
If you are using redux, you can use redux-persist to store your state on devices.
To share data between devices, you probably need to implement a remote server (cloud), which receives budget changes and propagates them to other family members.

I am very interested about what apps I can not create using flutter?
It seems like almost everything (except what?) can be done, and the only price of cross-platform is app speed.
The primary downside of using Flutter is library support. Only a very small number of libraries have been ported over. For instance, Realm is a popular database solution. It has not been ported to Dart or Flutter. So if you have either an existing app or an idea for an app that you want to develop in Flutter, then you should first think about what libraries you need (databases, maps, etc.) and then ensure that there exist the appropriate libraries.
Everything CAN be done in Flutter, but unless all of the main libraries you need have been ported over, it will be a lot of work. So in that case, you should choose a different framework.

I need to develop a prototype of an augmented reality app for research purpose.
This is my first time with augmented application and I only have basic knowledge on android.
The application is an android application that uses video overlay to display over the scene after detecting a target. The only problem is that the videos are obtained from another user (through another application that will allow user to record a video). The tutorials and examples I found allow you to attach the video to the target by developer not the the user and that's not my case.
Since either way I have to invest sometime to learn how to develop it. Whats you recommended environment? Android studio with **Vuforia. Vuforia with unity ? or other SDK? and I would appreciate if you have a slimier tutorial and samples.
It just a prototype therefore I'm not looking for high quality. Easy and less time consuming is my interest.
Unity 3D with Vuforia is easier for a beginner to understand. For more advanced functions you might want to use the Android Studio. I am not sure about how the user can attach a video to the target since normally, the developer has to include the video file in the Assets folder to attach it to target. This is how it is done in Unity. I hope someone can give you a better insight into this. But, I have worked with Unity/Vuforia and it is a pretty comfortable and easy environment for a beginner. All the best for your prototype :)

I'm considering a way to make an easy extensible iOS app. Let me explain, a client want's an app which is easy extensible with modules, so we can make separate modules and add them as wished to a base app. It have to be a possibility to make de modules in a new Xcode Project (it may be that inheritance of an interface is necessary). So in the end, de modules have to be added tot the Xcode Project of the base app and the new added module (UIView) is automatically added to the tab bar menu (or any other menu structure).
I'm not asking for code snippets but just your opinion of how to solve this problem or what the best way is to do it.
It sounds like you need to develop a framework. Find the pieces of the app that you want to be shared among other apps. Make that into its own, standalone entity.
On my projects, I have similar apps with different UI's. So the core of how data is retrieved and manipulated is all the same code. What differs is the UI.
That's the approach I would take.

With the new app-extension kit, I'd like to know if it's possible to build an app that tracks various usage statistics of other apps. For e.g., the no of times someone uses their calculator or the no of minutes spent on Quora.
This is a really nice idea to enhance the ability of iOS system. However, even in iOS8 this is unlike to achieve. Apple has offered so limited APIs for APPs to access other APPs. In those APIs, I cannot find any one to record other APPs' launching or closing. (Except you call that from your own APP so that you can record the time, but this is meaningless.)
In the official document for App Extension Programming, manager for APP is not a type that is mentioned in the guide. I'm afraid that you have read it and it cannot give you more help.
I tried to do research on the most detail list of iOS APIs to find whether this is possible. But since iOS5.0, Apple no longer provided the API diffs. Here is the search result.
