This is a sample project put together to submit a Rdar for a string interpolation memory leak we've identified in the Alamofire 3.4.0 release.
Run the sample app with the Leaks instrument to produce the memory leak. Here are the following details:
- iOS 9.3.1
- Xcode 7.3.1 (7D1014)
- Alamofire 3.4.0
The issue is caused by using string interpolation in the Timeline implementation of CustomStringConvertible and CustomDebugStringConvertible in Alamofire. Temporarily, we've moved over to string concatenation as a workaround to stop the leak in PR #1262.
Once the leak is fixed in Swift, we can move back to using string interpolation as that is certainly preferred.
This issue has been filed as rdar://26761490 on 2016/06/12 and can be found on Open Radar here.
This issue was resolved on Sept 1st, 2017 in Xcode 9 beta 6.
