My app has to integrate uploading image to set it as profile picture. The thing is all the images has to be stored in web services.
As web service has not been yet created. what is the best way to store images for temporary purpose so that i can integrate it easily when i have been provided with the backend.Sample tutorials can be helpful
My best idea is to use FTWCache (https://github.com/FTW/FTWCache) and cache it localy. Later, using webservice, you can still use your already written cache mechanism to implement NSURLConnection with caching. Profit! ;-)

I need to implement a chat into my app and im not sure on what to use and how. I don't know what is required for creating a chat, do I need to use some special stuff or is it enough with posting the messages to a database and then the other user retrieve that message?
You can use Firebase MBaaS with NativeScript, to make a chat app.
Or you can also take another approach and use QuickBlox, Parley, Applozic, Connectycube, etc.

If I wanted to make an app that allows users to add their own photos to a UICollectionview what method would I use? Also, how could that be added to Firebase's real-time database?
You need to give your users access to the camera and photo library.
You wouldn’t use the Firebase real-time database, you could use the Firebase Storage module, but I would use a product like Cloudinary, which allows you to do nice things like centring, resizing, facial detection etc.

I know this is probably a long shot but I wanted to know if there is any relatively easy way to run swift code which is stored on a server or hosted somewhere other than the application bundle. I would like to be able to change single lines of code without having to publish an update to the app.
If anyone could help or has a work around then that would be great.
Thanks
No it's both not possible (there is no compiler on an iOS device) and not allowed (downloading code is expressly forbidden by Apple's app store guidelines.)
So you both cannot and may not do this.

I'm creating a social media app.
I want to know a way to cache a users profile picture once downloaded from the Parse network and then each time the app is loaded check if an updated picture has been found and load that one, then cache that one.
I have no idea how to approach this, does anyone have any ideas?
There are plenty of third-party libraries for caching you can find on Github, or you can simply use NSUserDefaults or CoreData to save the pictures(or really anything) to disk. To check if a picture was modified, you can give the picture an identifier, compare it with the response from the server, and re-save the picture, or do whatever is needed.

I am fresh to the iPad app development. Now I am developing a calculator. And I want copy my result of the calculation to textEdit or to my mail which is outside the application. How can I do it?
if the text is selectable users should be able to copy and paste the information using the iOS clipboard themselves, this is probably the easiest option if you don't have a specific other application for them to copy to.
You can use Apple's APIs to send an email and put the result into the body/subject as necessary, this would provide a much nicer user experience.
See this answer for more details.
