iOS .app file larger than total Xcode project folder

Question

Contains the terminal .app unzip infoI built the iOS app. Total Xcode project size is under 100 MB only. After I built the app, I got the .app build size is nearly 300 MB. Why happen like that. It's also taking a long time (nearly 30 minutes) for build. How can I reduce the size of .app file and how can I make fast compile the application.

We need more information. Do you use build scripts? Fat Libs? ...? — shallowThought, Apr 04 '17 at 08:58
Build script means. I used cocoa pods in application which are also have small sized library. — KAREEM MAHAMMED, Apr 04 '17 at 09:07
I already some issues of similar types But they are saying that it is happening only in `x-code 8.3`. So which x-code you are using.? — dahiya_boy, Apr 04 '17 at 09:17
Im using Xcode 8.2.1 @agent_stack, Did you found any solution? — KAREEM MAHAMMED, Apr 04 '17 at 09:19
@shallowThought, I didnt fine Build Script under Target section. — KAREEM MAHAMMED, Apr 04 '17 at 09:22
@KAREEMMAHAMMED Try with different System after cleaning the derived data otherwise you have to report to Apple thats all I can say. — dahiya_boy, Apr 04 '17 at 09:24
Sorry. Its: Target-> Build Phases -> Build Script Phase (exists only if you or pods or someone added it). — shallowThought, Apr 04 '17 at 09:30
@KAREEMMAHAMMED Can you check your ipa structure and check what is taking so much space? Just rename `app.ipa` to `app.zip` and uncompress it and see the content of folder and package. Also if it's in swift then dylibs can take some of the space. — Inder Kumar Rathore, Apr 04 '17 at 09:40
@KAREEMMAHAMMED you can read my post similar to this here : http://stackoverflow.com/q/41907323/468724 — Inder Kumar Rathore, Apr 04 '17 at 09:42
@KAREEMMAHAMMED In your terminal your can run `unzip -lv app.ipa` command to see the content and it's size. Then post the output in your question so that we've more idea about your problem — Inder Kumar Rathore, Apr 04 '17 at 09:43
@InderKumarRathore i had done the unzip in terminal. Its a big list come. — KAREEM MAHAMMED, Apr 04 '17 at 10:27
@KAREEMMAHAMMED please put that in a txt file and give it's dropbox/drive link in your question — Inder Kumar Rathore, Apr 04 '17 at 10:31
@KAREEMMAHAMMED how are you calculating the size of your project? I mean can you show us your directory structure and its size? — Inder Kumar Rathore, Apr 04 '17 at 11:08

Your binary HealthNotes is of 155.11 MB which is obviously your code. I couldn't find any suspicious in the app. May be you can find which files are not required by your project. As far as I can see that your ipa size is 107900607 or 102.9MB see the last lines of your txt file. The 381102989 or 363.44MB is your uncompressed size.

I can see below files file which are large. Do check them if they are required.

Tips for Reducing app size

Use TinyPng to compress your images
Use image.xcasset so that app store can provide device based assets. Which will reduce the download size of the app.
Remove unnecessary images/fonts/html/pdf/sqlite/etc from your project.

The app has lot of files which made the ipa large.

Reduce Images usage
Change jpeg to png
Try decreasing png to small resolution
Remove unused files
Load images from web and cache it where possible
