I am developing an app for IOS and need MQTT client, I searched and there are similar questions asking which client to use for iOS, paho c client seems to be popular choice, but some people are suggesting that apple doesn't approve c clients for communication stuff. i have 2 questions.
1) which is most reliable/mature/complete MQTT client lib for iOS.
2) is it approved by apple and they will accept app that uses it.
I would prefer native objective-c libraries if they are available.
The 'MQTT Client Framework' is rock stable and is used e.g. in the iOS version of Owntracks. It has a lot of features compared to other libraries. The Owntracks app is available in the iOS App Store, so I guess Apple accepts this framework.
You can find a detailed blog post about the usage of the library written by the author here: http://www.hivemq.com/mqtt-client-library-encyclopedia-mqtt-client-framework/

I'm thinking of developing an app where you can look at each other's profiles (basically a Job-Finding Application) and I would like to know if you needed any knowledge of PHP, MYSQL for the databases and would you need any knowledge of Javascript to develop the application.
I'm currently looking at Google Firebase and also didn't know if that required any PHP knowledge?
All of the Firebase SDKs that you would use in your client app do not require any programming language knowledge other than what's required for your client platform. If you want to write entirely in swift, that's fine.
The only exception is Cloud Functions, which requires that you learn JavaScript to run on the backend.
iOS apps are built in Swift or C#, typically not javascript and never php.
You can build a PWA (progressive web app) that acts like an ios app using javascript Libraries such as react.
However, MySQL is a database that can be used with any number of applications and programming languages, so you should probably learn that.
My guess is that if you are asking this question, you probably should consult the Apple developer documentation before asking on this form.

I thought this would be the appropriate community to ask this question.
Back when Apple had their developer's conference over the summer, I was aware that they were going to make Swift open source.
I was under the impression that Xcode would not be ported to Linux, but I was under the understanding that some entity would create a development program to imitate Xcode.
Therefore, I am wondering about new developments in this situation.
Does anyone have any more current knowledge about this topic or any experiences with this?
There's a misunderstanding here.
Swift the programming language is open source.
It doesn't mean that iOS or OS X frameworks, like Cocoa, UIKit, etc, are available in Linux - Apple didn't announce that.
When you make an app for iOS using Swift, you have to import UIKit and other libraries - those are the iOS parts.
Swift is just the language - you can already make an iOS app with Ruby, Objective-C, JavaScript, etc, using these same libraries.

I wanted to check if its possible to build iOS app with both 32-bit and 64-bit support without using the new Unified Apis in Xamarin. Unified API support will require code changes in existing Xamarin iOS apps which are using MonoTouch Foundation and we want to avoid that.
Any pointers will be welcome
Thanks in advance!
No it is not possible to support 64 bit apps with the classic API. This is explained in the Xamarin blog post: http://blog.xamarin.com/unified-api-with-64-bit-support-for-ios-and-mac/
It is actually quite easy to update to unified, so i don't see a reason why you want to avoid that, also because it will be a requirement of Apple soon, and you can't publish new updates anymore after there deadline. For more information on how to update see the Xamarin documentation on that: http://developer.xamarin.com/guides/cross-platform/macios/updating_ios_apps/

If you were building a service like Instagram, when you need
-a web app
-android app
-ios app
How do you make the architecture for this to give enough flexibility to add another mobile system and keep the code as DRY possible? Do you have books to recommend about it?
In order to allow the server to support a wide range of client plattforms, I would make all client apps communicate with the server with the same protocol, so that the plattform the client runs on doesn't matter for the server. In an ideal case this would allow to add a new plattform without changing anything on the server-side
XmlHttpRequest is a good common denominator.

I'm developing a project for the iPad. My project is for a medical representatives. I need to populate their appointments, samples sold, to be delivered samples, etc.
I have to work with Cloud interface. For this I have got 2 words which I have to work with.
SalesForce
ZKSForce
I can see documentation about how to use this. But I want to know what is this? What is the purpose of using this.
Why to use SalesForce? Is ZKSForce a free library? Is there any other library apart from ZKSForce?
I need information about these two.
zkSforce is an open source cocoa library that accesses the salesforce.com SOAP api, You could use that or you could use the iOS Mobile SDK which uses the salesforce.com REST api.
