At the heart of Uber’s mobile app development are four primary apps: Android rider, Android driver, iOS rider, and iOS driver. Android developers build in Java, iOS in Objective C and Swift. Engineers across both platforms land code into a monolithic code base that ships each week.
They use some third-party libraries, but often build their own, since “Many open source libraries available are general-purpose, which can create binary bloat. For mobile engineering, every kilobyte matters.”
On Android, the build system is Gradle. For the UI, Butter Knife binds views and callbacks to fields and methods via annotation processing, and Picasso provides image loading.
As for iOS, all of the code lives in a monorepo built with Buck. For crash detection, KSCrash reports crashes to the internal reporting framework.
SwiftThe performance of Swift is almost the same as that of C++, which is considered the fastest in algorithm calculation arithmetics. Apple had this idea in mind and worked to improve the speed of Swift. For example, Swift 2.0 has beaten C++ in several computation algorithms, such as Mandelbrot algorithm. Objective-C is slower because it contains C API legacy.
Swift is faster than Objective-C, because it removed the limitations of C language and has been improved with the help of advanced technologies that were unavailable when C was developed. As mentioned by Apple, Swift was originally designed to operate faster.
Despite the fact that languages are different, they both integrate, and work with Cocoa and Cocoa Touch APIs, for all Apple platforms. Therefore, a regular app-user would not recognize the difference in operating speed between Objective-C vs Swift. Speed also depends on a programmer’s level and capabilities, since a slow app can be written in Swift as well.

C#C# is the most productive production language - it exposes a lot of functional conveniences along with the robustness of strong typing. And they're finally embracing the open source community - a huge plus.
#Language Features
We use the basic syntax (for, foreach, if,while) and object oriented constructs (classes, very simple inheritance).
We also use lambdas and block methods extensively, an intermediate level programming construct, but in a very formulaic and predictable way.
SwiftiPhone app, a new born language, it may good but the IDE, xcode is bad compare with Visual Studio. It just like a baby. playground can only use without connect to other library...you can not do a simply refactor of renaming a variable. You can go to definition and find reference, but you can not go to implementation....I should write them on xcode not here basically it is not the fault of swift, but it tightly to it, unless you want to use a notepad to write it.
C#PrometheanTV has used .NET and C# for several back-end applications and services including the Morphic Video Task System utilized to stream video assets to a variety of video delivery platforms including, Akamai, Brightcove, and others.
C++C++ is used in Shiro (https://github.com/Marc3842h/shiro).
C++ is a high performance, low level programming language. Game servers need to run with fast performance to be able to reliably serve players across the globe.
C#Unity3d builds the app and scripts are written in C#. It receives first class support from the Unity3d developer and most plugins exist in C# in comparison to Javascript (the other supported scripting language)
SwiftMost of our newer apps are written completely in swift, with our older ones and some special cases using a mix of Swift and Objective-C, but with Swift 2, the language is pretty much a must-use. "guard" is <3.
C#Used to create personal projects that call for a more organized approach to software architecture. Great stable 3rd party libraries in NuGet for tasks like creating web apps (ASP.NET Core) and IoC containers.
C++The most latency sensitive parts are written in C++. Due to our interconnected services architecture, we use either Python or C++ for each service, with the performance critical parts being C++14.
C#The main Carbonmade backend / API is written in C# and is ready to run on the CLR. We currently host on Windows but are preparing to migrate to Linux when the CoreCLR stabilizes.
SwiftFlutter is coded with Swift v.2.3 and can be run with Xcode v.8.2.1. To launch in Xcode 9.3, the code needs to be migrated to Swift 4.1
C++Used to write PHP extensions - AZTEC Decoder - License Driver scan - Axis2/C to PHP wrapper and Job-scheduler - Barbershop
C++Performance, zero-overhead abstractions and memory safety of the modern C++ language make this the perfect language for the project.
C++The main programming language of ApertusVR. C++11 & CMake provides multi-platform targeting. The architecture is modular.
SwiftMost of the app code was gradually rewritten in Swift for better performance and code maintenance.
SwiftOur native iOS app is built on Swift, and most of the basic function is still written in Swift
