By combining Tuist's binary caching with a custom selective testing plugin built on git diff and tuist graph, they cut CI build times by 65% (from 30 to 10 minutes) and reduced local UI test setup from 15 minutes to about 30 seconds. They now run a self-hosted Tuist instance for security and fast internal cache transfers, and plan to integrate their approach with Tuist's official selective testing feature. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How did Trendyol reduce their iOS CI build times using Tuist? Trendyol cut CI build times by 65%, from 30 minutes down to 10 minutes, by combining Tuist's binary caching with a custom selective testing plugin. The plugin used git diff and tuist graph to identify only the modules affected by code changes, so unaffected modules were pulled from cache instead of rebuilt, across a codebase serving 170+ iOS and Android developers. _daily.dev surfaces real-world case studies for teams weighing build caching strategies like Tuist._ ### How much can Tuist caching speed up local UI test setup in Xcode? Generating and opening a clean Xcode environment to start running UI tests dropped to around 30 seconds using Tuist's caching, compared to at least 15 minutes previously for a large-scale project. This was achieved by avoiding full rebuilds and reusing cached module outputs during local development. _Developers chasing faster local Xcode feedback loops can find similar experiences on daily.dev._ ### Why would a company self-host their Tuist instance instead of using a cloud version? Self-hosting Tuist within internal infrastructure ensures ultra-fast cache transfers over the internal network and guarantees compliance with internal security standards, avoiding external dependencies or potential security concerns while still getting the performance benefits of caching. _Teams evaluating self-hosted versus cloud tooling trade-offs can track similar decisions on daily.dev._ ## Similar posts on daily.dev - [Toss: Building less to ship faster](https://daily.dev/posts/toss-building-less-to-ship-faster-1arhtus0n) · Tuist · 4 upvotes · 0 comments - [The new Tuist, from build toolchains to bare metal](https://daily.dev/posts/the-new-tuist-from-build-toolchains-to-bare-metal-waw3c6jvd) · Tuist · 0 upvotes · 0 comments --- Tags: [#ios](https://daily.dev/tags/ios), [#cicd](https://daily.dev/tags/cicd), [#xcode](https://daily.dev/tags/xcode) [View this post on daily.dev](https://daily.dev/posts/trendyol-reduced-build-times-by-65--nnsspt5cc) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Trendyol reduced build times by 65%","url":"https://daily.dev/posts/trendyol-reduced-build-times-by-65--nnsspt5cc","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/trendyol-reduced-build-times-by-65--nnsspt5cc"},"datePublished":"2026-08-23T12:20:05.881Z","dateModified":"2026-08-23T12:40:36.897Z","description":"Trendyol, Turkey's e-commerce super-app with 170+ iOS and Android developers, adopted Tuist to tackle build times exceeding 30 minutes across a large...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f1e83a7de8cee703d8aa2783ac42fcdd?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f1e83a7de8cee703d8aa2783ac42fcdd?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"\n Tuist\n ","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"\n Tuist\n ","logo":"https://media.daily.dev/image/upload/s--3AYDH23h--/f_auto,q_auto/v1787487506/logos/tuist-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/tuist-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/trendyol-reduced-build-times-by-65--nnsspt5cc","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ios,cicd,xcode","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"\n Tuist\n ","item":"https://daily.dev/sources/tuist-blog"},{"@type":"ListItem","position":3,"name":"Trendyol reduced build times by 65%"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/trendyol-reduced-build-times-by-65--nnsspt5cc#faq","mainEntity":[{"@type":"Question","name":"How did Trendyol reduce their iOS CI build times using Tuist?","acceptedAnswer":{"@type":"Answer","text":"Trendyol cut CI build times by 65%, from 30 minutes down to 10 minutes, by combining Tuist's binary caching with a custom selective testing plugin.
