Environment Variables

Override configuration at runtime — useful for switching between demo configs and CI/CD.

Xcode Setup

Edit Scheme → Run → Environment Variables

Variable	Values	Description
`VIO_CONFIG_TYPE`	`viaplay`, `tv2`, `automatic`	Loads `vio-config-<type>.json`
`VIO_ENVIRONMENT`	`production`, `development`, `sandbox`	Override environment
`VIO_USER_COUNTRY`	`NO`, `SE`, `DK`, `GB`…	Override market country check

Multi-Config Setup

Useful for demoing multiple clients (Viaplay, TV2) from the same codebase:


App Bundle
├── vio-config-viaplay.json     → VIO_CONFIG_TYPE=viaplay
├── vio-config-tv2.json         → VIO_CONFIG_TYPE=tv2
└── vio-config.json             → default (no variable needed)

Config Priority

VIO_CONFIG_TYPE environment variable → loads vio-config-<type>.json
vio-config.json (no variable)
vio-config-automatic.json
vio-config-example.json
SDK defaults

Load from Environment Programmatically


// Reads VIO_API_KEY, VIO_ENVIRONMENT, VIO_CONFIG_TYPE from ProcessInfo
ConfigurationLoader.loadFromEnvironment()

Country Override


// Load config, then check market availability for Norway
ConfigurationLoader.loadConfiguration(userCountryCode: "NO")

Combined with VIO_USER_COUNTRY in the scheme, useful for testing market availability without changing code.
