However, further setup is required to run tests or programs directly on a device.

First make sure you have a valid developer certificate and have setup your device properly
to run apps signed by your developer certificate. Then install the libimobiledevice and
ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from

Il existe de nombreuses situations où vous devez signaler une erreur à un client qui utilise votre API.

Ce client peut être un navigateur avec un frontend, un code d'un tiers, un appareil IoT, etc.

Vous pourriez avoir besoin d'indiquer au client que :

* Le client n'a pas les privilèges suffisants pour cette opération.
* Le client n'a pas accès à cette ressource.

 * migrate between certificate authorities. Do not use certificate pinning without the blessing of
 * your server's TLS administrator!
 *
 * ### Note about self-signed certificates
 *
 * [CertificatePinner] can not be used to pin self-signed certificate if such certificate is not
 * accepted by [javax.net.ssl.TrustManager].
 *
 * See also [OWASP: Certificate and Public Key Pinning][owasp].
