What is the value of adding a key/value pair to the project's ist? The value of the key/value pair is updated at build time. Set the key to BASE_URL and the value to $(BASE_URL).
Xcode project build settings code#
Your code cannot directly access the build settings you define. Īs the name implies, a build setting is available during the build process. Set the value for Production and Release to and the value for Staging to. Click the triangle on the left of the user-defined setting to show the list of build configurations. What is the benefit of defining a user-defined setting? The user-defined setting allows us to set a value for BASE_URL for each build configuration. Defining a base URL is common for applications that interact with a backend. Click the + button at the top and choose Add User-Defined Setting. It's possible to expand this list with build settings that you define. The Build Settings tab shows the build settings for the Configurations target. Select the Configurations target from the Targets section and click the Build Settings tab at the top. Before I lay out the solution I have in mind, I'd like to show you another solution that is often used by developers.Ĭhoose the project in the Project Navigator on the left. In this episode, I show a solution I use in any project that has some complexity to it. User-Defined Build SettingsĪs I mentioned earlier, there are several solutions to manage data that is specific to a particular build configuration. The schemes make it quick and easy to switch between build configurations. We now have a build configuration for staging and production. Select Run on the left and set Build Configuration to Production. With the scheme selected, click the gear icon at the bottom and choose Duplicate. Select the scheme named Configurations and click it one more time. Select the scheme at the top and choose Manage Schemes.
Let's create a scheme for each configuration to make it easy to quickly switch between environments. Click the + button at the bottom of the table, choose Duplicate "Staging" Configuration, and name the configuration Production. Let's add a third configuration for the production environment. Double-click the Debug configuration and rename it to Staging. The staging environment is used during development. Many applications communicate with a backend and it's a common practice to have a staging and a production environment. You commonly use the Debug configuration during development whereas the Release configuration is used for creating App Store or TestFlight builds. A brand new Xcode project defines two build configurations, Debug and Release.
Select the project in the Project section to show the project details. Open the Project Navigator on the left and click the project at the top. Tell Xcode where you'd like to store the project and click Create. Name the project Configurations, set Language to Swift, and make sure the checkboxes at the bottom are unchecked. Adding a Configurationįire up Xcode and create a new project by choosing the Single View App template from the iOS > Application section. There are several strategies to manage build configurations, but there are important differences you need to consider, especially in the context of security.
Xcode project build settings how to#
In this episode, I show you how to safely manage data that is specific for a build configuration, such as API keys, credentials, and other sensitive data. This isn't new and it's a good practice to use build configurations to tailor a build to the specific needs of the environment it's going to be deployed to. Most projects define one or more additional build configurations for various reasons.
