[ios] Max size of an iOS application

What is the maximum size of an iOS application? any constraints?

50 Meg is the max for Cell data download.

But you might be able to keep it under that in the app store and then have the app download other content after the user install and runs the app, so the app can be bigger. But not sure what the apple rules are for this.

I know that all in-app purchases need to be approved, but not sure if this kind of content needs to be approved.

Now Accepting Larger Binaries February 12, 2015

The size limit of an app package submitted through iTunes Connect has increased from 2 GB to 4 GB, so you can include more media in your submission and provide a more complete, rich user experience upon installation. Please keep in mind that this change does not affect the cellular network delivery size limit of 100 MB.

With the release of iOS 7 (September 18th, 2013) apple increased the over-the-air cellular download limit to 100MBs.

Maximum app size remains 2GBs.

150MB is the constraint for over-the-air downloads via the cellular network. Anything above that and users will be suggested Wi-Fi or iTunes sync to actually get your app.

This will not prevent a purchase though, at point of sale.

Please be aware that the warning on iTunes Connect does not say anything about the limit being only for over-the-air delivery. It would be preferable if the warning mentioned this.

As of June 2019, if your user's are on iOS 13 the cellular download limit has been lifted. User's just get a warning now. Read here

Short Answer:

1. If your game is released for iOS 9.0 or newer, you can have maximum app size of 400 MB for the size of the Mach-O binary file (for example, app_name.app/app_name).

2. Your app’s total uncompressed size must be less than 4 Gb.

Long Answer:

Your app’s total uncompressed size must be less than 4 billion bytes. Each Mach-O executable file (for example, app_name.app/app_name) must not exceed these limits:

For apps whose MinimumOSVersion is less than 7.0: maximum of 80 MB for the total of all __TEXT sections in the binary.

For apps whose MinimumOSVersion is 7.x through 8.x: maximum of 60 MB per slice for the __TEXT section of each architecture slice in the binary.

For apps whose MinimumOSVersion is 9.0 or greater: maximum of 400 MB for the size of the Mach-O binary file.

However, consider download times when determining your app’s size. Minimize the file’s size as much as possible, keeping in mind that there is a 100 MB limit for over-the-air downloads. Abnormally large build files are usually the result of storing data, such as images, inside the compiled binary itself instead of as a resource inside your app bundle. If you are compiling an image or large dataset into your binary, it would be best to split this data out into a resource that is loaded dynamically by your app.
