How to integrate ButterCMS into your iOS application

Just follow the simple steps below to complete the integration and begin creating pages with Butter. Be sure to check out our full guide to creating pages using the ButterCMS iOS API.

1. First, install our swift package with either the Swift Package Manager or CocoaPods.

For Swift Package Manager:

  • Select XCode > File > Swift Packages > Add Package Dependency.
  • Provide this git repository: https://github.com/ButterCMS/buttercms-swift.git.
  • Then set your version, e.g. 1.0.7

For CocoaPods:

  • Install CocoaPods if not installed already with $ brew install cocoapods
  • Create a Podfile in the root directory of your project with $ pod init and open your generated podfile. For example: $ open -a Xcode Podfile.
  • Update your podfile so it reads like the below snippet, then run $ pod install

target 'YourAppName' do


pod 'ButterCMSSDK', '1.0.7'


2. Initialize the SDK:

To get started with the Butter API, instantiate the ButterCMSClient with your ButterCMS API token.

// Initialize Butter client 

import ButterCMSSDK 

var butter = ButterCMSClient(apiKey: "YOUR_API_KEY")

3. Fetch posts or pages:

All ButterCMS Single Pages and Page Types have a configurable Page schema. In order to fetch a Page via the Swift SDK, you'll need to model the Butter Page schema as a Codable Struct and pass it to the getPages API, which will allow the SDK to deserialize the page data for you.

This is different from Blog posts, which have a fixed data model. For example, to fetch all blog posts, you can use the SDK's getPosts() function:

import ButterCMSSDK

var butter = ButterCMSClient(apiKey: "YOUR_API_KEY")

butter.getPosts(parameters: [



  .page(value: 1),

  .pageSize(value: 10)

      ]) { result in

  switch result {

  case .success(let posts):

      //Do something on success

      print("Count: \(posts.meta.count)")

      posts.data.compactMap() { print("Post: \($0.title)") }

  case .failure(let error):

      //Do something on failure

      print("getPost failed with Error: \(error)")



4. Integrate into your application.

ButterCMSDK calls to the posts or pages API return JSON responses, like the below sample, which can be easily integrated into the framework of your choice.


  "data": {

    "slug": "homepage",

    "name": "HomePage",



    "page_type": null,

    "fields": {

      "seo_title": "Anvils and Dynamite | Acme Co",

      "headline": "Acme Co provides supplies to your favorite cartoon heroes.",

      "hero_image": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV",

      "call_to_action": "Buy Now",

      "customer_logos": [


          "logo_image": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV"



          "logo_image": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV"
