How to do conditional compile based on target names?

Question

I'm using testflightapp.com SDK in my project to track crashes during beta test which is conducted on testflightapp.com. I have 2 targets in my Xcode project, which are "ad-hoc" and "app store".

To initiate testflight SDK, I need to put down a line of code in the AppDelegate.m like:

[TestFlight takeOff:@"67bebb8d8e5396a...A4LjQwNjQ4NA"];

Now, I want the compiler to exclude this line of code when I compile for the target "app store", because it doesn't make sense to trigger testflight SDK when it goes to public.

I'm expecting something like #ifdef, but I couldn't get a clue by searching the forum.

Answer 1

You can use a user-defined build setting that you set in the build settings for each target, and then use an #if or #ifdef directive to test that setting. For example, select your 'ad-hoc' target, click on 'Build Settings', and scroll down to the 'User-Defined' section. Then just click the 'Add Build Setting' button and choose 'Add User-Defined Setting'. You can set different values for your setting for each build configuration (debug, release, etc.).

Answer 2

It is a old post but would like to share another way to achieve this.

The solution is like create few (depends on how much targets you have) files with same class/function/variable but added to different targets.

Like for me, I have main target and UITest target so I have following two files

BuildConfiguration_main.swift added to main target.

struct BuildConfiguration {
    static let isMainTarget = true
    static let isUITestTarget = false
}

BuildConfiguration_UITest.swift added to UITest target.

struct BuildConfiguration {
    static let isMainTarget = false
    static let isUITestTarget = true
}

Then in you code, you can use BuildConfiguration.isMainTarget or BuildConfiguration.isUITestTarget to tell where is target the code is running if you share some codes between two targets.
