# [fit] What do we use CI for?
---
1. Automated testing
2. Static analysis (linting etc)
3. Beta deployment
4. Release build deployment
---
# [fit] What were build times like?
---
- 1st build: 55 minutes
- 2nd and later: 35 minutes
---
# [fit] What did they become?
---
- 14-16 minutes
---
# [fit] How?
---
# [fit] Caching frameworks
---
- Moving to Carthage and using [Rome](https://github.com/blender/Rome)
- Biggest impact: 55 to 33 minutes
---
# [fit] What is Rome?
^ Rome is a tool that uploads and downloads prebuilt binaries from Carthage to a variety of storage services. I use AWS S3 because it's popular and cost effective (less than 3,000 yen per month)
---
# [fit] Upgrading plan
---
---
- Not much to explain here
- 33 to 20 minutes
---
# [fit] Only getting code coverage when tests change
---
- 2 minutes less
---
# [fit] Remove pointless indexing
---
---
- Saves 1 or 2 minutes
```sh
COMPILER_INDEX_STORE_ENABLE=NO
```
---
# [fit] Other techniques I look forward to
---
- Parallelization
- Separate modules
^ Parallelization: run static analysis at the same time as building + testing. Separate modules means better caching for incremental builds. xcode's build system has to be conservative for what really needs to be rebuilt to avoid dangerous mistakes
