Breaking changes may happen often during this\ntime.\n\n## Why Not Use Auto Layout?\n\nRCL intends to offer the following advantages over Auto Layout:\n\n * **Explicit and linear layout.** Reactive layout proceeds in a linear fashion,\n   making it easier to understand and debug the steps it takes along the way.\n * **Top-down layout.** A view's layout doesn't interact with its superview's\n   layout unless the former's size or frame is explicitly incorporated in the\n   latter's layout chain, creating a unidirectional relationship that leads to\n   better encapsulation (no global priorities!) and less complexity.\n   Bidirectional relationships are still possible, but must be made explicit.\n * **Conditional layouts at runtime.** RCL is built on the full power\n   of [ReactiveCocoa](https://github.com/ReactiveCocoa/ReactiveCocoa), and signals can\n   be composed to dynamically disable and re-enable entire layout chains (like\n   when you want to hide and show views) without actually modifying them.\n * **Implicit animations.** To animate the setting of a view's frame, simply add\n   an animation method into the signal chain. No need to explicitly animate\n   constants anywhere.\n * **Incremental use.** RCL can be used internally in views without any\n   implementation details leaking out. Callers using Auto Layout or struts and\n   springs can incorporate reactive views without knowing or caring how they\n   perform layout internally. No UI-wide slowdowns or behavior changes just from\n   using RCL!\n * **Extensibility.** RCL is made up of many independent bits of functionality\n   unified into a framework. It's easy to extend it with your own functionality\n   if you want it to behave differently.\n * **Not a black box.** Unlike AppKit and UIKit, RCL is an open source project,\n   so you can crack open any particular bit and see why it behaves the way it\n   does.\n\n## Getting Started\n\nTo start building the framework, clone this repository and then run `script/bootstrap`.\nThis will automatically pull down any dependencies. Then, simply open\n`ReactiveCocoaLayout.xcworkspace` (note: not the `.xcodeproj`) and build.\n\nTo use ReactiveCocoaLayout in your project, you will need to include the `ReactiveCocoaLayout.xcodeproj` (note: not the `.xcworkspace`) file in your project, and link\n[ReactiveCocoa](https://github.com/ReactiveCocoa/ReactiveCocoa) and\n[Archimedes](https://github.com/github/Archimedes) into your application target.\n\n## License\n\nReactiveCocoaLayout is released under the MIT license. See\n[LICENSE.md](https://github.com/ReactiveCocoa/ReactiveCocoaLayout/blob/master/LICENSE.md).\n","funding_links":[],"categories":["Objective-C","**Index**"],"sub_categories":["ReactiveCocoa should transform EVERYTHING when it comes to writing iOS code so here's a bunch of projects that should make your RAC transtion a little bit smoother"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FReactiveCocoa%2FReactiveCocoaLayout","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FReactiveCocoa%2FReactiveCocoaLayout","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FReactiveCocoa%2FReactiveCocoaLayout/lists"}
