Our code uses several (custom) compilation conditions (search for SWIFT_ACTIVE_COMPILATION_CONDITIONS).
| Compilation Condition | Description |
|---|---|
DEBUG |
Development/Debug builds should be considered the opposite of RELEASE. Code wrapped in DEBUG is assumed to work only on non-production environments such as unit- or ui-testing. |
RELEASE |
true if the app was built in release-mode. We mainly use this flag to disable certain features (developer menu, logging, …) for production. If you want to disable a certain feature for production you should use #if !RELEASE as opposed to #if DEBUG. |
COMMUNITY |
true is the Community build configuration/schema has been selected. The Community configuration enables other developers to run the app in Simulator. |
USE_DEV_PK_FOR_SIG_VERIFICATION |
true if the app should use the dev-public keys for the signature verification. This is only set for testing and during development. In case this is set mistakenly to true the app simply stops working. |
DISABLE_CERTIFICATE_PINNING |
true if certificate pinning should be disabled. This is NEVER EVER set for builds that will end up in the App Store. We only use this for debugging purposes. |
The previously existing UITESTING flag has been removed in favor of an environment variable XCUI with value YES. A convenience property isUITesting has been set up.
To prevent possible 'leaks' of test code into production releases it is recommended to wrap all usage into DEBUG flags. Example:
#if DEBUG
if isUITesting {
// UI test code
}
#endif
