How to access Build Settings in Xcode 6?
ios, swift, xcode
Solution
Here's how to set it up:
- Add a User-Defined setting to your target's `Build Settings` (which you did with `WEB_SERVICE_BASE_URL`)
- Add a new row to your target's `Info.plist` file with key: `WEB_SERVICE_BASE_URL`, type: `String`, value: `${WEB_SERVICE_BASE_URL}`
Here's how get the value:
let api_key = Bundle.main.object(forInfoDictionaryKey: "WEB_SERVICE_BASE_URL") as? String
Note: These keys/values can be extracted from the package, so be sure to avoid storing sensitive data in there.
Problem
There seems to be a lot of variations of how to access the Build Settings variables (i.e. to define the base URL of a web service for different `Debug` vs. `Release` environments). I created a User-Defined variable in Project -> Building Settings, one for each environment. Let's call it `WEB_SERVICE_BASE_URL`. How do I access it in the code? I'm using XCode 6 and Swift. I've tried this but it doesn't work ``` let api_key = ${WEB_SERVICE_BASE_URL} ``` I've also tried this and it also doesn't work ``` let api_key = NSUserDefaults.standardUserDefaults().stringForKey("WEB_SERVICE_BASE_URL") ``` Any suggestions? This seems to be a often needed solution, it's so easy in Rails, but not so in iOS development.
