In my last update my application size was 36 MB when i uploaded on app store. Then i added some pods files like Firebase Database ,storage and JSQMessagesViewController in my project after that when i uploaded my application its size increased and it become 101 MB. I'm shocked that how it is increased so and why? How can i reduced this size like about 40 MB? I have also used Bridge Header File in my project because firebase chat code is in swift and my project is in objective C.

You can export an archive to an ipa from the organizer. Then rename the ipa file to .zip and extract it.
From there, you'll be able to see what component is taking how much space.
This is the file structure for my app that has been extracted

I recently wanted to use an open source library that dropped Cocoapods support so I decided to migrate my entire project over to using Swift Package Manager. That means no more using the .xcworkspace file and now opening the .xcodeproj file instead. Is there a difference among settings that occurs when using the .xcodeproj instead? I noticed my project is always indexing first thing when I open it and when I build my project Xcode jumps to 110% CPU utilization and stays there even after the build and is idle. This makes the experience inside Xcode a bit laggy. Anybody else experiencing this? Is this expected? What’s the best way to go about trying to figure out what’s going on?

I'm starting a project in which i can view all image's/Documments/files all the phone storage data of the iphone device.
Like File Explorer app in which we can see all folder and data in the storage in the Iphone devices and i can do all operations like cut, copy image's, file's etc to another folders in phone.
example :- like we have Es file explorer application in android. I need to create it for iphone.
Can copy image's to OTG device's. create , update , delete file's, etc
any links of tutorials or suggesting site for this project.
For Example for IOS : - IUSB Drive app.
You can use FileProvider.
Using this your app can access the documents and directories stored and managed by your other apps.
There are some Limitation that you can't do all features like ES File explorer does.

I am developing an application. It takes 20 seconds to build into my iPhone, but couple of minutes to archive into an IPA, what is the reason of this ?
I use Xcode 6, and Swift.
EDIT :
i once read about dsym option that could be turned off, and save a lot of time, are there any other options that i can turn off to save time?
That's obvious because the archiving does a lot of optimisation and compression on the code and resources (images etc), which takes additional time than just installing a debug build.
As far as I understand it archiving an app is building it ánd compressing it's not weird that it takes longer than only building. You may have a look at this: https://en.wikipedia.org/wiki/.ipa_(file_extension)

Apple states that an iOS App binary file can be as large as 2 GB, but the executable file (app_name.app/app_name) cannot exceed 60 MB? Does that mean that on the App Store, when I download my app that it can be as large as 2 GB? Or is it required that my app be less than 60 MB including all my images and video?
If my app including images and video must be less than 60 MB, how can I retrieve the rest of my assets?
The .app file portion is limited to 60 MB and consist largely of your compiled code. When combined with the assets (images, sounds, videos, data, etc.) in an .ipa file, the maximum size is 2 GB.
Note that these limits change over time. See: Max size of an iOS application

I have an iOS app that has over 100 images pre-stored in it. I want to have a system where all the images are saved online and picked by the app. Other then maintaining an own server, what other online options are available to save and retrieve such amount of data. And what are options available to save high scores of the iOS application online?
Parse could be made to work to save and access the images.
Game Center is great for high scores and Crystal, Geosophic, and Plus+ are all alternatives as well.
you can integrate apple's iCloud in your app to store any data.
this is the link-https://developer.apple.com/library/mac/documentation/General/Conceptual/iCloudDesignGuide/Chapters/Introduction.html
for store high scores you may use game centre.
