Cash App Case Study Getting the benefits of KMM without leaving their rut
Alec intense from Cash App shares their tale of adopting KMM and benefiting from provided code across their platforms that are mobile.
Cash App may be the way that is easiest to deliver money, spend some money, spend less, and purchase cryptocurrency. We believe in supplying everyone else with access to essential financial services so they may be able completely take part in the economy. The app established in 2013 as a simple peer-to-peer payment application with 4 mobile designers, plus it now has 50 mobile designers (split across iOS and Android os) and 30 million monthly active users.
The choice to test out Kotlin Multiplatform started in available source. a collection we maintain called SQLDelight ended up being gearing up to create Kotlin-only APIs, additionally the decision ended up being designed to also use KMM to create those generated APIs platform-agnostic. The fit seemed natural. Since SQLite is considered the most commonly used cross-platform technology around, this would serve as an opportunity to test the technology, and it would open the d rs for Cash App to utilize it later on, considering that the Android os form of the application relied heavily on the collection at its core.

Within the year that is last weвЂ™ve made major modifications to exactly how we utilize Kotlin Multiplatform to aid teams to l k at it. We had initially introduced the Gradle t lchain to the iOS build by maintaining the provided rule into the same repository, however the additional cost of operating Gradle and rebuilding the project did not seem sensible in light of how often the dependency had been changed. Alternatively, we created a shared repository for Android/iOS become the home for our provided business logic. Since that time, our network, investing, and growth groups have all built features with elements of their business logic in KMM. Exactly What has made me most proud is the fact that contributions attended not merely from Android and iOS downline, but through the server group aswell! Since we use Kotlin for our server-side development, their group has become datingmentor.org/seniorblackpeoplemeet-review/ able to work in the repository, and because the platform-agnostic Kotlin so closely resembles Swift that the change is manageable for the iOS team t .
As well as using SQLDelight, we utilize CrashKiOS from TouchLab to have better stack traces in the open, so we have been in the entire process of adopting Wire to work well with protocol buffers into the shared codebase. In terms of which areas of our business logic weвЂ™ve encouraged KMM being a solution for, weвЂ™ve had the absolute most success so far with perseverance and pure functions within the provided code, and next weвЂ™re hoping to operate more closely with this community APIs using Wire.

We love Kotlin Multiplatform we love about our work because we didnвЂ™t have to give up any of the things. WeвЂ™re at destination now in which the developer workflow is unchanged but there is a choice to generally share rule and obtain all of those benefits without stepping out of our rut. Our teams are increasingly realizing the potential of KMM, providing it an attempt, and seeing just how effective it’s.
