You can also check Erick Camacho\u0027s [talk at AltConf 2019](https://www.youtube.com/watch?v=QVwOzfJIDCc) about it.\n\nThe tool supports creating reports of different kinds to analyze the content of the logs. XCLogParser can give a lot of insights in regards to **build times** for every module and file in your project, **warnings**, **errors** and **unit tests** results.\n\nThis is an example of a report created from the Build Log of the [Kickstarter iOS open source app](https://github.com/kickstarter/ios-oss).\n\n![kickstarter build report](images/kickstarter-ios.png)\n\n## How and Why\n\n`XCLogParser` is written as a [SPM](https://github.com/apple/swift-package-manager/) executable and it supports three commands:\n\n1. [Dump](#dump-command) the contents of an `xcactivitylog` into a `JSON` document.\n2. [Parse](#parse-command) the contents of an `xcactivitylog` into different kind of reports (`json`, `flatJson`, `summaryJson`, `chromeTracer`, `issues` and `html`).\n3. Dump the [Manifest](#manifest-command) contents of a `LogStoreManifest.plist` file into a `JSON` document.\n\nDepending on your needs, there are various use-cases where `XCLogParser` can help you:\n- Understanding and detailed tracking of build times.\n- Automatically retrieve unit test results, warnings and errors.\n- Build other developer tools for usage outside Xcode.\n- Automatically and continuously data delivery for historic analysis.\n\n## Installation\n\nYou can compile the executable with the",
