We have a problem that our app update regularly shows up way bigger than the app actually is with app thinning. This is because the App Store show you the complete size of the app, with all its resources and screenshots and icons. However when you download the app, this is the actual size of the app itself, without all the extra unnecessary resources screenshots and description. Also, if you use App Thining, the app itself won't download all the resources for the specific device, what means that this again decreases the actual app size.

Let's take the example app called SOEX. The actual app run on the iPhone will have 50mb size including storyboard, code, and all resources. However, there are also 5mb of screenshots for the App Store and your 2x and 3x assets. This iPhone is using the 1x assets. All those extra assets are 15mb. This brings the total uploaded file to apple to 70mb. This is also the amount that will be displayed on the iPhone's App Store, whereas the storage displayed in the settings will be 50mb only.

Now, when you will switch to an iPad this will likely be even larger, as the storyboard is different for the iPad assuming you have two storyboards rather than size classes and constraints. So the iPad size will be 55mb , whereas the iPad App Store display will show you 75mb.

Now to the third value, that is when you will check the size on your computer. Here it will likely be the biggest as it'll contain all the assets, both storyboards and all you code. Because of all the resources for the different resolutions and sizes, the App Store displays a larger number than what you will actually download. SDKs contributed roughly 3. SDK vendors can be unprepared for new iOS releases, which can block key releases and announcements.

Or, SDKs can occasionally introduce bugs, and even a single crash can mean a would-be user will never use your app again.

Therefore, it makes sense to limit the number of SDKs you bundle into your app in order to optimize for performance. Segment built an easy, lightweight solution called the Native Mobile Spec. The Native Mobile Spec automatically collects events that allow you measure top mobile metrics without any tracking code.
