Impact Analysis
The following numbers are representative of a skeletal sample app integrated with the Helpshift Unity plugin.
App Launch Time
Since all the Helpshift initialization takes place on a background thread, the Helpshift SDK does not affect app launch times.
v5.6.0
Disk space
Tested with Unity 2019.4.20f1, Xcode 12.0 built demo app on iPhone X running iOS 14.0. Memory Usage will increase with number of FAQs and number of messages in a conversation.
When an Unity iOS app is integrated with Helpshift framework, the increase in the size of IPA file is around 3.8 MB for both bitcode and non-bitcode variants of the framework.
If your app is not already using swift, there will be an additional ~2.6 MB size addition in the final downloaded IPA for OS versions below iOS 12.2.

iOS 6 deprecation
Starting with unity plugin version 2.x, we officially dropped support for iOS 6. But we had kept the code handling the differences in platforms iOS 6 and below. With SDK version 2.3.0 and above, we have now removed all handling in our code so running your application on iOS 6 is likely to cause runtime crashes and bad behaviour.
v2.2.0-support
The combined library size (libSupport.a) is 15.8 MB. The breakup is as follows:
| Architecture | Size (MB) |
|---|---|
| i386 + x86_64 (simulator) | 5.8 |
| armv7 | 3 |
| armv7s | 3 |
| arm64 | 4 |
When compiled with an app for deployment on the app store, armv7, armv7s and arm64 will be taken up and i386+x86_64 or the simulator architectures will be ignored.
Sample compiled payload size using a demo app
Helpshift SDK would add about 1.3 MB to your app's bundle.
SDK memory usage
Memory usage for the SDK support screen launches. Helpshift's install call will add around 1.2 MB of memory usage to your app.
Memory usage tested with a demo app. Usage will increase with number of FAQs and number of messages in a conversation.

| showConversation | 5 MB |
| showFAQs | 7.9 MB |
| showFAQSection | 7 MB |
| showSingleFAQ (depending on the content of the FAQ) | 5 - 10 MB |
