4GB's is the maximum size your iOS app can be.
As of January 26, 2017
App Size for iOS (& tvOS) only
Your app’s total uncompressed size must be less than 4GB. 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 500 MB for the total of all __TEXT sections in the binary.
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.
This information can be found at iTunes Connect Developer Guide: Submitting the App to App Review.
